The phone call from Carl Bertil Johansson in early summer 2009 came out of the blue. The founder of the Swedish company CBJ Tech had read an article I’d written about military Personal Defence Weapons (PDWs) for soldiers who do not normally carry a rifle. I had concluded that the optimum weapon configuration would be a compact machine pistol like the 9mm Brügger & Thomet MP9. I had also observed that the gun’s ballistics could be transformed by adapting it to fire the 6.5×25 CBJ cartridge. He thought this idea sounded promising so had contacted Brügger & Thomet, who were interested enough to supply him with an MP9 featuring a prototype barrel in 6.5×25 calibre. Initial testing had made him so enthusiastic that he was calling to invite me to Sweden to try the gun and ammunition combination for myself. How could I refuse?

The MP9

The MP9 has been developed from the Steyr Tactical Machine Pistol or TMP, to which Brügger & Thomet acquired the rights in the early 2000s. This innovative Swiss company has made a number of modifications, the most obvious being a side-folding shoulder stock, which transforms the steadiness of aim and the effective range. They have also added a NATO accessory rail on top for optical sights, ghost ring rear sights with an adjustable foresight, a trigger safety (similar to the Glock system), a suppressor attachment on the barrel sleeve (B&T also make the suppressors), and translucent magazines for 15, 20, 25 or 30 rounds. Options include a Picatinny rail under the barrel in lieu of the fixed handgrip, and a fixed skeleton rather than folding stock. The standard colour of the body is black but green and coyote tan are also available, as is a blue version adapted to fire Simunition FX training ammunition (which can also work with the new Force on Force cartridge recently introduced by ATK) and a red “manipulation” gun which cannot fire live ammunition and is used for safe handling training.

The result is an exceptionally compact and lightweight submachine gun or machine pistol, largely made from polymer and weighing just 1.4 kg (3.1 lbs) empty. Loaded 9mm magazines weigh 240 grams (8.5 oz) for 15 rounds to 440 grams (just under 1 lb) for 30 rounds. The MP9 is 303 mm (11.9 inches) long with the stock folded and 523 mm (20.6 inches) with the stock unfolded. Barrel length is 130 mm (5.1 inches). Unlike most SMGs (with the notable exception of the Heckler & Koch MP5 series) the gun fires from a closed and locked bolt, utilising a rotating barrel locking system; it will still fire when the muzzle is pressed against the target. The cyclic rate of fire is 750-800 rpm. The single shot/automatic selector and manual safety switch is a push-button by the thumb.

According to B&T, about 5-6,000 MP9s are sold every year. The gun is widely exported and is now in service with many special forces and close protection teams. The use of the ubiquitous 9mm cartridge is a significant selling point, along with the compact dimensions, the open holster (the gun clips into it) and the availability of the training versions. The modest penetration of 9mm ammunition isn’t felt to be an issue as hardly any of the expected opposition use body armour (this may not, of course, remain the case indefinitely), and around 50m is regarded as an adequate range for its particular role.

The nearest competitor to the MP9 is the Heckler & Koch MP7. The most obvious difference between them is that the MP7 is available only in HK’s unique 4.6×30 calibre, whereas the MP9 fires the 9×19 NATO, aka Parabellum or Luger, which is readily available from many manufacturers in a very wide range of loadings. At least, that was the case until recently, when the first example of the B&T MP9 in the 6.5×25 CBJ version appeared.

The 6.5×25 CBJ

Carl Bertil Johansson is an experienced gun designer who has worked with Aimpoint and SAAB Bofors among others, but set up CBJ Tech to develop his idea for a high-performance cartridge. The company, a family-run business, is based in southern Sweden and owns a Cold War bunker that provides very secure accommodation for workshops and range testing.

CBJ started development of the 6.5×25 cartridge in the late 1990s at the time of the NATO competition to select a new PDW round. This was intended to replace the 9×19 with longer-ranged ammunition able to penetrate NATO’s CRISAT target (equivalent to contemporary Russian body armour) at 150 metres. The only cartridges officially tested were the 5.7×28 FN developed for the P90, and HK’s 4.6×30 for the MP7. It proved impossible to reach political agreement on which to choose, so no decision was made.

FN and HK both started with “clean sheet” ammunition and gun designs, but Carl Bertil decided on a different approach, reasoning that a cartridge that was interchangeable with the universal 9×19 round by means of a simple barrel swap would have a much wider appeal. It would mean that existing guns could be adapted to fire the new cartridge, and also that guns in the new calibre could be easily changed to 9×19 if required; even the magazines remain the same.

This design principle meant that the new CBJ cartridge would have the same overall dimensions as the 9×19 (including the rim diameter) and would need to develop a comparable recoil impulse to ensure reliable gun functioning. The cartridge that emerged from this study was the 6.5×25, with an extended, necked-down case and a short bullet protrusion. Several different loadings in three ballistic groups have been developed.

To compete with the 5.7mm and 4.6mm rounds in meeting the NATO PDW long-range penetration requirement, a sub-calibre loading is used. The standard military “ball” loading is actually a 4mm calibre tungsten bullet in a plastic sabot. The bullet weighs 2 g (31 grains), 2.5 g with its sabot. There is a “spoon-tip” version designed to encourage more rapid bullet upset on impact, and a training variant using cheaper core material. All of these are fired at a muzzle velocity ranging from 730 m/s (2,395 fps) from a 127 mm (5 inch) barrel (the recommended minimum barrel length) to 900 m/s (2,950 fps) from a 305 mm (12 inch) barrel. The tungsten-cored loadings fired from a 12 inch barrel match the trajectory of the 5.56×45 NATO from an M4 Carbine and have much superior penetration to its standard SS109/M855 ammunition, being able to punch through 9mm armour plate. From a 12 inch barrel, velocity at 300 metres is 578 m/s (1,900 fps) at which range it will still penetrate the CRISAT target.

The 6.5mm version of the MP9 has the barrel extended to 150mm (5.9 inches), giving a muzzle velocity of just over 800 m/s (2,620 fps). By comparison, the 5.7×28 P90 and 4.6×30 MP7 both fire as standard 2 gram (31 grain) bullets at about 720 m/s (2,360 fps). A brass-jacketed 6.5mm ball round weighs 7.5 grams (115 grains) compared with 6.2-6.4 grams (96-99 grains) for the 5.7 and 4.6 rounds and around 12-13 grams (185-200 grains) for 9mm. Loaded 15 and 30-round 6.5mm MP9 magazines therefore weigh about 165 and 290 grams (5.8 and 10.2 oz) respectively. Steel and light-alloy cases are being considered by CBJ, but the initial emphasis is on brass.

The other ballistic groups fire full-calibre 6.5mm bullets. One group, primarily intended for police use, fires lightweight 2.5 gram (38.6 grain) bullets at the same velocities as the sub-calibre loadings. These consist of the HET (high energy transfer) brass bullet and a frangible (polymer/metal powder blend) version for use in training or when barrier penetration needs to be minimised. The HET will also penetrate the CRISAT armour target at short range, but these rounds are most effective within 50 metres as the lightweight bullets rapidly lose velocity. The third ballistic group has just one round – subsonic armour piercing – intended for use with a suppressor. It is much heavier than the other bullets at 8 grams (123 grains) and can also penetrate the CRISAT target.

The 6.5×25 cartridge cases were previously made by reforming 9×29 Winchester Magnum brass, but CBJ Tech now has cases specially made for them. These use slightly thicker brass, requiring some adjustment to the propellant loads. The colour of the sabots has not yet been firmed up; originally these were black but this was changed to white to aid recovery from the indoor range’s backstop which has an outer layer of shredded black rubber. For production purposes, different colours may be used to indicate the loading.

SAAB Bofors was initially involved in helping to market the 6.5x25mm while the NATO competition was running, but is no longer involved with the project. CBJ Tech is continuing to develop the ammunition and demonstrate its capability in a wide variety of converted submachine guns and pistols. Those tested to date range from the Steyr AUG SMG to SIG Sauer and Glock pistols. Where necessary, pistols are fitted with barrels extended to 5 inches. A substantial purpose-designed SMG, the CBJ MS, was initially developed to use the new round and features a folding bipod and an optional large-capacity drum magazine in order to act as a light support weapon out to 400m. However, CBJ Tech is now mainly focused on adapting existing 9mm weapons, particularly the MP9 as this is seen as the ideal combination for the PDW role in which there is growing military interest. The remarkable performance of the 6.5mm cartridge, especially in armour penetration, is such that CBJ is intending to offer their conversions only to military and police customers.

How it Works Together: the MP9 in 6.5×25 CBJ

Once in Sweden I had the opportunity to test-fire the MP9 in both 9mm and 6.5mm calibres alongside other weapons for comparison purposes, in two locations; an outdoor range in semiautomatic fire and in CBJ’s indoor range on automatic. Before this, I had only been able to handle the MP9 so I was keen to see how it performed.

In either calibre the MP9 is a pleasure to shoot. I found the spacing between the butt, the pistol grip and the forward handgrip suited me well. The fat, forward-sloping front handgrip greatly aids control and I would certainly not wish to do without it. For semiautomatic fire the little 1.5x Trijicon sight proved ideal and the effective range of the 6.5mm version firing the saboted tungsten ammunition would probably be around 200 metres. In 9mm calibre or for close-range work a 1x holographic red-dot sight (also tried) might be preferred.

Given the MP9’s small size and weight I was surprised by its controllability in automatic fire. As a UK civilian my opportunities for firing automatic weapons are nearly zero but I found no trouble in keeping the rounds on target when firing short bursts; the little gun was much easier to control than an M16 I tried afterwards.

There was very little difference between firing the 9×19 and 6.5×25 versions of the MP9. Subjectively, the 6.5mm version felt as if it had slightly less recoil. My arrival coincided with CBJ’s working up of loads using their new cartridge cases. They hadn’t finalised this process and the 6.5mm version suffered some failures to feed with the new cases (although it performed very well with the older ones) but that was expected to be a temporary glitch.

A key question in my mind was this: OK, the little 4mm tungsten bullet goes through armour like the proverbial hot knife through butter, but how does it perform against unarmoured personnel? This question could only finally be decided in combat, of course, but ballistic gel provides a repeatable substitute for testing purposes. CBJ Tech has the facilities for this, and performed some tests for my benefit. I witnessed three different cartridges being compared at about 5 metres range; the standard 6.5mm saboted ball (this one first had to penetrate a CRISAT target), the full-calibre 6.5mm HET and the 9×19 NATO FMJ. The results are shown in the photograph. The least impressive was the 9mm, while the 6.5mm HET showed far more disruption with rapid bullet upset. The saboted ball also performed significantly better than the 9mm, and according to previous tests I was shown, the spoon-tip version demonstrates even faster upset as one would expect. Interestingly, on one of the test shots of the saboted rounds the sabot was found stuck into the surface of the gel block, which showed that it had followed the bullet down-range quite closely.

To sum up, the Brügger & Thomet MP9 is arguably the best of the new breed of PDWs – or machine pistols or compact SMGs if you prefer. For only about double the size and weight of a pistol (but half the size and weight of an M4 Carbine) it offers perhaps ten times the effective range plus controllable automatic fire. The use of universally-available 9×19 ammunition is proving to be an important benefit, but if more range or penetration is required the gun can easily and reversibly be converted to the impressive and versatile 6.5×25 CBJ. For any military or law enforcement organisations contemplating a weapon in this class, this could be a winning combination.

Every so often there are ideas or products that are introduced in the firearms industry that every observer agrees are quite good but for one reason or another just don’t make it to market or are unsuccessful. It could have been bad timing, bad marketing, a lack of resources or just bad management. The story of the MP9 is an interesting story about how a potentially good product that for all practical purposes was dead and was about to be buried, has now has been reborn for a second chance to serve law enforcement and military the world over.

Those who read the last article can guess the MP9 started life many years ago as the SPP/TMP submachine gun. From a commercial point of view it never really made it in the world market because it was never fully developed and poorly marketed. Another handicap with Steyr was the lack of a decent international network in which to plug in new professional products. The limited number of countries that are using the AUG rifle serves as a testimony to this fact.

In 2001, non-industry investors bought out Steyr. Like any new owner of any acquired company, they reviewed the profit and loss of each product and decided to drop the TMP. They did this because the volume of units sold did not justify keeping it in the product line. The fact that there were ways to revive and re-launch the product was of no interest to businessmen who wanted return on their investment as soon as possible. That is business.

Brügger & Thomet (B&T) had an ongoing relationship with Steyr on some other projects and understood the shortcomings of past TMP marketing and made the Steyr management an offer for all the drawings, licenses, spare parts and current inventory. The Steyr management thought this was a great deal because they were just going to destroy everything; and in late 2001 B&T acquired all the rights to the SPP/TMP worldwide.

Since then B&T has taken their time to improve what was already a pretty good little design. B&T made over 19 different engineering changes and added features to the gun and finally renamed it the MP9 for Machine Pistol 9 millimeter.

Some professional readers might already know of Brügger & Thomet as one of Europe’s best known manufacturers of firearm suppressors and upgrade accessories to many weapon systems mostly to law enforcement, NATO and NATO partner countries. They are also the OEM (Original Equipment Manufacturer) supplier to most of Europe’s weapon manufacturers that include, HK, SIG, Beretta, Swiss Arms, Walther and Glock. In 2002, B&T received an award from HK as being one of its most reliable suppliers. Out of a possible 100 they received 99.6. Germans, by the way, never give 100 to anyone.

Producing a submachine gun, however, is much different that making a suppressor but B&T has experience with this as well. B&T produced its own version of the MP5. Not just only in one version but in all versions to include the MP5SD. They have dropped this product all together in favor of the MP9.

When one picks up the MP9, the size and weight is what one first notices. It weighs only 1.3kg (2.87 lbs) which makes it the lightest 9mm submachine in the industry. Some may say the Glock 18 (709 grams/1.56 lbs) and the Beretta 93-R (1,170 grams/2.58 lbs) are lighter but these are not really submachine guns but just pistols with full automatic capability and are very difficult to control. The Glock does not even have a shoulder stock, which is necessary if required to fire accurately. For a better comparison, the MP5K for example is a bit over 2 kg (4.41 lbs) and the MP5PDW is 2.78 kg (6.13 lbs). The MP9 is almost half the weight as the MP5PDW. Another point that is a factor here is that the MP9 stays in battery when making a contact shot when the operator places the muzzle of the weapon right up against the target. This point was well illustrated during a presentation to an Asian country’s navy who were responsible for boarding suspect freighters. In the close quarters, the operator chose to use his pistol as opposed to the MP5 for clearing the ship and had to make a contact shot with a pirate with his pistol. The pistol went out of battery and couldn’t fire with the situation quickly becoming a wrestling match until the operator’s partner could shoot the pirate at point blank range.

The size of the MP9 with the stock closed is only 30.5 cm (12.01 in). There are smaller submachine guns in the world like the MAC10/11 and Vz61, but these are obsolete by either firing the 7.65 ACP cartridge or from an open bolt and thus are unsuitable for today’s professional users. An operator can even carry the MP9 comfortably under a normal suit jacket using the B&T carry holster which was designed like an IPSC rig and can be attached to the belt loop attachments made by Safariland, Uncle Mike’s or Blackhawk.

The MP9 also has a nice smooth design with no exposed moving parts to get hung up on clothes or equipment. This makes the weapon’s size and weight ideal for many different applications, including: VIP & close protection teams, military & police special forces, vehicle crews, helicopter & aircraft crews, commanders and officers, police patrol weapon, plain clothes and undercover surveillance teams.

Another big plus with this design is the polymer construction of the MP9. Polymer is impervious to rust which makes it suitable for marine and combat diver operations. To that effect, the entire outer envelope of the pistol is made of a synthetic material. Another thing about polymers that many people often overlook is the potential to mold the weapon in different colors to be mission specific for the operator. The MP9 takes maximum advantage of this feature and is available in Black, Coyote Tan, Green and Red.

The ergonomics (and safety for that matter) are greatly enhanced by the integrated forearm grips of the MP9 that keep the hand of the operator away from the muzzle. When combined with the integrated folding stock, it allows for a very stable firing position. The magazine well is in the handgrip of the MP9 and is a much faster and efficient way of reloading any weapon. This method of operation is known as the “hands-find-hands” design and is so much quicker a typical operator can reload the MP9 in about one-third the time it takes to reload an MP5.

When it comes to training, the MP9 is from the start, “Ready for the real world…” by having an optimized FX Training version available. In the past, there always seemed to be a schism between the industry’s ammunition and firearms manufacturers. This has almost always been the case with FX Training ammunition. Why should a gun producer R&D and produce a version of their weapon that will benefit a single ammunition manufacturer? This is the first time a firearm producer has developed an FX firing version from the very beginning of the development of the weapon. So many special units in the world have adopted the FX for force on force training it is a must to have a compatible system. From the very beginning, B&T cooperated directly with SNC Technologies in Canada so that their MP9FX works as well as any other kit in production. It is a dedicated unit produced in training blue for safety. With a FX unit, units can really train the way they plan to operate. This is impossible with all the other PDWs on the market today.

This brings up a problem with all the new PDWs and calibers that are promoted in the world. These are namely the 5.7mm from FN Herstal and the 4.6mm from Heckler & Koch. When their engineers developed these systems, the concept of force on force training was not addressed. Many units or agencies use Simunition but found they had to forgo their real world scenario training if they adopted the new caliber. This could be a reason why these new calibers have not been nearly as successful as the manufacturers would have liked because of this faux pas.

B&T also came up with a clever idea when it comes to training with the MP9 by producing a red, non-firing manipulation gun called the MP9R. This is a non-gun and, like the MP9FX, cannot be made to fire live ammunition. The MP9R is ideal for rehearsals, immediate action drills, weapon retention, defensive tactics training or any one of a number of ways when an instructor or an operator has to point the weapon perhaps in the direction of other persons, like when explaining a firing stance. Simply put, no one has ever been shot or killed with a red non-gun.

The magazines are translucent in color so the operator can visual cue how many rounds are remaining in the magazine. This could be critical under stress when making tactical reloads. Most operators, if they are honest with themselves, would find if difficult to count how many they have fired, especially when firing full automatic bursts. If for some reason the operator does not want these clear magazines, black ones are available. The extremely durable plastic material lends itself to many years of tough use. It can be easily disassembled for cleaning and is impervious to chemical and any cleaning fluids. The MP9 comes with two magazines: one 15-round magazine, and another 30-round magazine as standard. Other magazines are also available in 20 and 25-round capacities. Custom size magazines are available as well as magazines in unique colors; for example blue when using Simunition FX or CQT ammunition

The MP9 employs a rather ingenious delayed blowback, short recoil operation featuring a rotating barrel. At the moment of firing, the barrel is solidly locked to the telescoping bolt via eight locking lugs with both parts moving rearward for a short distance. The barrel is then suddenly stopped and rotated free of the bolt, after a brief delay caused by resistance from the opposing torque of the bullet’s rotation. The bolt continues its rearward travel alone, completing the cycle of extracting and ejecting the fired casing, recocking the internal hammer and disengaging the sear. At this point the bolt is stopped and then begins to move forward under pressure from the recoil spring, chambering a round from the magazine. As it slams shut, the bolt forces the barrel to rotate into the locked position, ready for the next shot. This helps to limit the recoil impulse, and to reduce the cyclic rate, which is 800-900 rounds/min. This firing system, while not requiring a gas system, is very reliable and will continue firing even while the weapon is fouled. The Mean Rounds Between Failure (MRBF) of the MP9 is over 5,000 whereas all the other submachine guns on the market are much lower. As a result of this method of operation, the MP9’s perceived recoil is much reduced as compared to other 9mm submachine guns. Thus, it is capable of delivering greater accuracy in automatic fire than other submachine guns. At five meters (16.40 ft) distance, a good operator using a good stance can fire a 30-round burst and keep all 30 rounds in a 5 cm (1.97 in) group.

The cocking handle of the MP9 is quite similar in design to that of the Colt M4 and is located at the rear of the upper receiver. This is another nice safety feature as it will keep the hands of the operator away from the muzzle; especially critical when under stress.

The MP9 has a round post for a front sight that is adjustable for elevation by turning it with a screwdriver. There is no need to have a special sight adjustment tool that no one seems to have when it comes time to adjusting the point of impact. The top of the upper receiver has a molded M1913 Picatinny rail that allows the mounting of a variety of optical sights. Other submachine guns on the market require a special mounting system for what is becoming a must these days. The MP9’s open sights, however, were found to be quite adequate for most of the uses that this gun is bound to encounter. These are a ghost ring type design but the ghost ring sights are backup sights. B&T believes that subguns need to have an optic and approached Aimpoint some four years ago with a proposal for a very small optic and an open purchase order for what was recently introduced as the Aimpoint Micro T-1. After much R&D, Aimpoint developed what was considered an ideal match for the MP9. The trigger mechanism gets overall high marks for safety and simplicity. All the operator needs to do is pull the trigger back to fire. This system is not too unlike the Glock trigger design. This trigger incorporates an automatic safety that prevents the hammer from falling unless the trigger is actually pulled and thus acts as a drop safety. For the TP9, there is also a manually activated cross bolt trigger safety that any left or right handed operator can fire.

Suppressor are important for a weapon like this for a variety of reasons such as command and control, firing at night with or without night vision devices because it effectively masks muzzle flash, which also masks the location of the operator. A suppressor will reduce recoil and adds ease and safety to training, enhances friend or foe recognition and even increases accuracy. Many readers saw the suppressors used in Afghanistan when clearing the caves near Tora Bora. If an operator fired his weapon without a suppressor in any enclosed area he will not be able to hear what orders were being given by the team leader.

A PDW Competitor?

When B&T came out with the MP9 the idea was to make a submachine gun for a niche market of close protection, law enforcement and special military use. One of the surprises to B&T was how several NATO countries requested samples of the MP9 to evaluate as a possible PDW in lieu of a weapon chambered for any of the new calibers such as 5.7mm and 4.6mm. It seems that more than a few countries are not convinced that the new calibers are the wave of the future. This seems to be based on lack of proven terminal ballistics, readily available 9mm ammunition (to include new high performance armor piercing 9mm) or probably, and most likely, the logistical problems with introducing a totally new caliber into the organization.

Another point is that the enemy has changed when the original requirement for an armor piercing capable PDW was written in the late 1980s. In those days, the cold war was still going strong and NATO planners were concerned about in the event of war with the Warsaw Pact armies disrupting NATO command and control, logistics and communications centers using Spetsnaz Commando or what the Soviets called “Diversionary” troops. These special operators would wear body armor that consisted of many layers of a textile ballistic material and even titanium plates. On April 1, 1991 the Warsaw Pact alliance officially disbanded and many former members applied for membership into NATO and the EU. For ten years planners vacillated trying to predict when and where the next war will be. September 11 answered that question and the current profile reveals that the present enemy does not wear a bullet proof vest but a bomb vest. If the bad guys do not wear body armor then the operator does not need armor piercing ammunition. If the operator does need armor piercing capability then there is 9mm AP rounds that can defeat 3A body armor at 50 meters. If you are going to engage a target beyond that distance the operator is much better off using a short barrel assault rifle. The sizes of assault rifles have come down. For example, an HK G36C, when in the folder position,is exactly 500mm (19.69 in) long. The length of the FN P90 is exactly 500mm long. There is no need for an operator to compromise on the terminal ballistics. If size is an issue, the MP9 is a good choice. If range is an issue then a short rifle is a good choice and the need for a PDW as we have come to believe it must be reevaluated.

(TP9 US BATF classified as pistol)

For those readers who are unaware, the US firearms market is the “Holy Grail” for most of Europe’s manufacturers. It is a huge, single and dynamic market that represents the potential to make any manufacturer or product a household word if successful. It is safe to say that if Glock was not as successful as it was in the US their world position would be much different than it is today. Many of the well known manufacturers have wholly owned manufacturing facilities in the US. SIG, FN Herstal and Berretta are making weapons in the US and now HK has announced its plans to build a facility in South Carolina. Americans don’t seem to have prejudice for ‘Made in the USA’ over European made products in the firearms industry. Even the US military is using almost exclusively European designed or produced products. The Beretta 92 is called the M9, The FN MINIMI is called the M249 SAW, the MAG is called the M240B, the SIG 228 is called the M11 and even the current M16 is made by the FN Herstal factory in Columbia, SC. Colt, however, still has the M4 contract but FN won the SCAR contract for the US Special Operations Command.

The B&T/DSA Connection

In 2005, B&T entered into a relationship with DS Arms (maker of the SA-58 rifle, the only US made FAL) to develop a BATF approved tactical pistol version of the MP-9. DS Arms and B&T have worked together for the last 10 years, and B&T was able to create a BATF approved pistol version of the MP-9 that is legal for importation into the US. The new pistol was designated TP-9, short for Tactical Pistol, and was introduced at Shot Show 2007.

Based on the design, available ammunition, ergonomics, training possibilities and flexibility, any professional user would be well served by taking a closer look at this weapon. It is not for everyone, but depending on the mission it could be a good tool in completing the mission and keeping people safe in what is becoming a more and more unsafe world.

DS Arms is the exclusive US importer for B&T products and the TP-9 pistol. DSA carries most of the items in the B&T product line, and stocks B&T rail systems and tactical accessories. For a list of available products and pricing, as well as more info on the new TP-9 pistol, check out DSA’s website at www.dsarms.com. DSA also carries a host of B&T accessory items for the TP-9 pistol. DS Arms celebrated its 20th year anniversary in 2007.

If you are interested in purchasing a TP-9 pistol or accessory items, please have your dealer contact the following distributors: Ellett Brothers, RSR Group, Sports South, and Zanders Sporting Goods. Law Enforcement or agency sales inquiries should be made directly to DSA at (847) 277-7258.

I make a habit of perusing European gun magazines. Not only do I get a different perspective of shooting and firearms, but I often get advanced information about new products before they appear on our shores. Several years ago I began to notice that a Swiss suppressor company called “Brügger & Thomet” was mentioned in more and more advertisements and articles. Cursory examinations of their suppressors (or as they are called in Germany and Switzerland “schalldampfers”) in Swiss gunshops showed they were very well made and robust in construction. However in all honesty I must admit that my interest, while somewhat piqued, was still not enough for me to investigate further. This all changed though when I read in gun publications such as Shotgun News, Gun List, and last but not least Small Arms Review, that not only were Brügger & Thomet (pronounced Brewger & Tommet) suppressors being offered for sale in the US, but that Heckler & Koch had adopted B&T suppressors after they passed a grueling 10,000 round endurance test. I happened to mention in passing to a Swiss friend of mine that I would like to visit their company. As luck would have it my friend (who is also a gun dealer) was acquainted with Messrs. Brügger & Thomet and arranged an appointment for me to visit their offices.

Brügger and Thomet was founded in 1992 by Karl Brügger and Heinrich Thomet and is located in Spiez, Switzerland. Spiez, about 50 kilometers southeast of Bern, is found in the heart of some of the most beautiful mountains and lakes in Europe if not the world. Herr Brügger and Thomet were long time automatic weapons enthusiasts and the liberal (in the classic sense of the word) gun laws of Switzerland allowed them to actively pursue their interest. In the late 80’s and early 90’s the MP-5 became a very popular submachine gun in Switzerland. Just as in the United States, most “MP-5’s” started out as Hk-94’s semi’s and were then converted to full auto as Heckler & Koch would not sell any factory MP-5’s to civilians. There was also a demand for the MP-5SD (the SD being an acronym for schalldampfer) and a number were converted to this version as well. Unfortunately many of the SD conversions were poorly executed and were a far cry from the Oberndorf models. Enter Messrs. Brügger & Thomet.

Karl Brügger and Heinrich Thomet felt this situation was intolerable and began to search for ways to fix the poorly converted MP-5SD’s. Before I go further you have to understand the following: Prior to January 1st, 1999, there were absolutely no restrictions whatsoever on suppressors in Switzerland. A Swiss citizen could just walk into a gunshop, buy a suppressor, and walk out. No tax, no paperwork, and no license. This freedom gave a steady market for suppressor sales and ready feedback on their performance. Through hard work, experimentation, and lots of sweat, Brugger & Thomet began to gain a solid reputation for quality and dependability. Gradually the partnership evolved and Herr Thomet became the Managing Director and Herr Brügger, who is by trade a mechanical engineer, the chief designer. As the firm grew, B&T created their own designs and continually improved upon them always searching for new techniques in manufacturing and materials.

While B&T worked on their line of suppressors they also became a retail firearms dealer selling rifles, pistols, ammunition, and accessories to the public. As time passed the firm evolved and grew from being a retailer to the sole Swiss distributor for companies such as Heckler & Koch, Beretta, Steyr, Trijicon, Eagle Industries, and others. Currently the Brügger & Thomet partnership has three divisions: The B&T Trading and Consulting Division which buys, trades, and sells obsolete/surplus weapons (B&T was responsible for exporting 50,000 Austrian StG-58 FAL parts kits to America), the Manufacturing Division which develops and manufactures suppressors and other accessories, and finally the Representing Division which represents the aforementioned companies.

Arriving on a sunny Friday afternoon in August I was greeted by Herr Thomet and sat down for a pleasant chat. He discussed the history of the company and how it had changed over the years. Every time I speak to someone like Heinrich Thomet I feel a little guilty and am very grateful for their time as I know just how busy a successful entrepreneur is. Phones and faxes were busy ringing away and employees were unpacking inbound crates and packing outbound ones. Later we were joined by Herr Brügger and they showed me some their current products.

I was particularly interested in their Impulse II-A suppressor as this model was adopted by the elite German KSK Commando’s and survived the aforementioned 10,000 round endurance test by Hk with no damage to the test pistol or suppressor. Hk was so impressed by the quality and durability of B&T suppressors that they entered into a contractual agreement with them and now sell Hk pistols matched and serial numbered to the B&T can. This acceptance by Hk was no mean feat as Hk has incredibly high standards. Karl showed me an Impulse II-A that was rejected by Hk for having nothing more than a slight scratch on the tube that was barely noticeable.

The Impulse II-A shares most of the same internal characteristics of other B & T suppressors. The tube is constructed from aircraft grade aluminum and the six steel baffles are made of a special Swiss ordnance steel called ETG-100. All told, the Impulse II-A weighs ten and one half ounces and is affixed to a threaded barrel with a locking ring. The II-A is designed for 9X19, 10 MM, .40 S&W, and .45 ACP handguns that utilize Browning style barrel locking designs. The impulse module (also called a Nielsen device) can easily be adjusted to change the impact point of the bullet without the operator going crazy adjusting the sights. This is a great feature as the pistol can shoot close to the same point of aim whether the suppressor is attached or not. The unit is simple and easy to disassemble for cleaning and the shooter needs no tools. The Impulse II-A has a sound suppression of -36 db wet and -26 db dry.

What I found intriguing with B & T suppressors was the unusual six fluted step cone baffle design. Karl told me he got the idea for this design while working as an apprentice in the Swiss Government Powder Factory (similar to our Rock Island or Picatinny Arsenal) in 1983. The basic concept had been developed at the factory but the Government had done nothing further with the design. Karl continued to refine the concept on his own after he left the factory and developed it into the present system.

Following the Impulse model Karl then showed me their MP-5 QD (Quick Detachable) model and it really lives up to its name. Karl produced an MP-5 and after a little practice I could pop it on and off in three or four seconds. Once on the weapon and locked down you would swear the can is welded to the barrel. The three standard protruding barrel lugs fit into a corresponding collar on the suppressor which in and of itself is sufficient to lock the can on the weapon. However there is a twist-literally. With nothing more than a spring lock to hold the suppressor it would be possible in CQB and other scenarios for the operate to inadvertently slam the weapon into an object (or lets be frank here-a hard contact shot to an enemy) which could dislodge the can. The B&T design holds the suppressor on the barrel by the spring loaded locking collar and a manually twisted locking ring. All you have to do is snap the can on the barrel, give the locking ring a twist and a half, and voila, it’s attached! If the shooter wants to drop the can and shoot loud, B&T has a quick detachable five prong flash suppressor that locks on the barrel in the same manner the sound suppressor does.

Heinrich let me have a sneak preview of a prototype suppressor and barrel for an M-249 SAW (FN Minimi to the Europeans) that was really neat. The can slides over an integral flash suppressor on the barrel so an operator isn’t blinded by the flash or gives away his position in a tactical situation when the can is removed. A similar system is used on their SOPS Assault Rifle Suppressor except the flash suppressor allows the use of rifle grenades. They also make several suppressors for 7.62 NATO sniper rifles and even have a model for a Barrett Light Fifty-a weapon that can really use one!

Currently B&T has sold over 11,200 suppressors worldwide which means they must be doing something right. Try as I might I couldn’t find out just which high speed, low drag units were using B&T suppressors. Part of this is do to the fact they sell their products wholesale to companies such as SIG and Hk who market them on their own. The other reason is that a number of their direct customers have non-disclosure clauses in the purchase contract and B&T is not allowed to reveal this information.

B&T also makes a number of scope mounts that allow the use of the Aimpoint and several other brands of holograhic sights on such diverse weapons as the AK-47 and MP-5. Complimenting their scope mounts is B&T’s line of tactical light mounts for ASP flashlights that mount on pistols, submachine guns (particularly the MP-5), and assault rifles. Karl also showed me the blueprints for a new design he created to mount an ASP tactical light to an MP-5 and then asked me, “Sam what are you doing this evening-would you like to go shooting?” (“oh gee, I don’t know, let me think for a moment, well,uhhhhhhh, I guess so” ). I immediately said yes and we made plans for a rendezvous later that evening.

After a fine traditional Swiss dinner with my wife, Karl picked me up at the hotel and off to the range we went. Arriving at a rather non-descript looking building, we entered and descended down a flight of stairs and I found myself in a modern underground shooting facility replete with pro shop, cappuchino/snack bar, and dining area. There was also a spectator gallery from which visitors could look out into a multi-lane 25 meter range. The range was divided in two sections: a 25 meter paper target range with automatic target placement and retrieval, and a 25 meter row of 10 inch falling plates with remote control reset. In all honesty I must admit that I have never liked indoor shooting ranges, however if all were as nice as this one I’d probably change my mind.

Karl opened his range bag and withdrew ammo, magazines, an Hk USP in 9 MM, one of B & T’s Impulse II-A suppressors, and we prepared to make ready. We ran a man sized silhouette target out to 15 meters and Karl handed me the USP now loaded and sporting the Impulse II-A. I squeezed off five rounds at the center of the target and immediately noticed the absence of any holes. Well, color me embarrassed. Now I know that when someone misses a target that badly a popular refrain is, “Well geez, it ain’t me! It’s gotta be the gun!”. But seriously I didn’t see how I could miss with all five shots-after all, I’ve earned four Expert Diplomas from Gunsite, at least proving that I can hit the floor with my foot once in three tries. Karl said, “don’t worry”, disassembled the suppressor, and adjusted the index ring. He then reassembled it, locked it once more on the USP, and handed it back to me saying, “Try it now”. I fired five more rounds and noticed a world of difference- five shots about three inches above point of aim at 15 meters falling roughly into a two and a half inch circle. Five more rounds fell in the same area and didn’t open the group any larger-now this was more like it!

All told I ran about 150 rounds through the USP both with and without the Impulse II-A and except for the reduction in sound, the only other characteristic I noticed was a decrease in the pistols cyclic speed. Accuracy and reliability appeared unimpaired. Moving on to something with a little more power Karl pulled out his MP-5/10 in 10 MM.

I’m a big fan (fan as in fanatic) of the full power 10 MM. For a number of reasons I think the 10 MM is the best pistol cartridge in the last 30 years. I mentioned this earlier to Karl whereupon he asked if I had ever fired the MP-5 in 10 MM. When I told him I hadn’t he brought his along. Perched atop his MP-5/10 was an Aimpoint holosight on a B&T mount. The nice thing about the B&T mount is that it rests very low to on the weapon and allows the use of the factory installed iron sights. Springfield Armory was so impressed by this mount they became the exclusive US distributors for it. At this point we moved to the falling plates side of the range and both Karl and I fired a number of mags through the “Ten”. The Aimpoint on the B&T mount coupled with the MP-5/10 made short work of the plate rows.

While Karl and I were taking turns on the MP-5/10 I noticed a gaggle of rubberneckers in the spectator area who were pointing their fingers at us and studying our every move. I was puzzled as to their behavior. I mean yeah, sure, we were shooting subguns and suppressors-but that’s not really that big of a deal in Switzerland. Karl noticed me staring at them and anticipating my query said, “German tourists, they can’t believe we can own these here!”. Mystery solved.

About this time the owner of the hotel we were staying at and a friend of Karl and Heinrich’s showed up at the range with his MP-5A3 also fitted with a B&T suppressor. We fired a number of mags through it, and, like the Impulse II-A, it worked flawlessly. I also must admit that I could shoot the falling plates faster and more accurately with the “Nine” than I could with the “Ten”.

Several weeks later I toured B&T’s factory and was very impressed. Almost every part and component, other than a few finishing processes, is done on state of the art CNC machines. The nice thing about CNC tooling from a diversification aspect is that a manufacturer is not strictly tied to one type of enterprise. For instance everything from prototype artillery shell components for the Swiss Army, to artificial hips (no joke), was being produced alongside suppressor baffles.

In conclusion I was very impressed by Brügger & Thomet. They have got the gun business down cold. That is they understand guns and business. How many times have we seen someone who knew guns and had a great product(s) go bankrupt because they didn’t understand business. On the flip side I have witnessed successful firearms firms and one major firearms training center lose money and respect because they acquired a bean counter at the helm who didn’t understand guns. Karl Brügger and Heinrich Thomet however are dialed in and a I predict a long and profitable future for their partnership.

Due to red tape caused by a plethora of bureaucratic barnacles, Brügger & Thomet suppressors manufactured in Switzerland are not available in the United States. However they are manufactured under license here by Capitol City Firearms (P.O. Box 29009, Richmond, VA, 23242, phone 804-740-4926, fax 804-740-9599) and follow the same strict tolerances and quality control standards as the Swiss models. If you want a suppressor with a new age design built with old world craftsmanship I strongly suggest you check out Brügger & Thomet.
