The MAS-38 was France’s first officially adopted submachine gun, rushed into service in 1940. It was basically too late to help with the defense of France, with less than a thousand delivered by June 1940. The Germans kept the gun in production, making 20-30 thousand under the designation MP722(f...

The Star Z-63 is a 9x19mm version of the Star Z-62, which was made in both 9x19 and 9x23. Together, these represent the company’s effort to produce a more modern submachine gun than their Z-45, which was basically a copy of the German MP-40. The Z-63 is, contrary to its external appearance, a wel...

The Uru, named for a tropical bird, is a Brazilian 9mm submachine gun made from 1977 until 1985 and used by Brazilian military and police forces. What makes it interesting is the designer’s focus on simplicity - the gun has just 17 parts, and basically no screws or pins (except the bolt holding t...

The M-56 is a Yugoslav take on the MP-40 design, produced starting in 1956 to replace its previously issued M49 submachine gun (which was a copy of the Soviet PPSh-41). The M56 is simpler than the MP40, however, and chambered for the 7.62x25mm Tokarev cartridge. It is a simple gun to make, but qu...

The Spanish-made MP41/44 is a licensed copy of the Erma EMP submachine gun. The development begins with Heinrich Vollmer in 1925, designing a submachine gun for German military testing. The military trials showed a number of flaws in the gun, and Vollmer updated the design to fix them - but by th...

The Lanchester MkI was the first British effort to produce a domestic submachine gun during World War II. The British military had rejected these types of arms as "gangster guns" prior to the war, and did not see them as useful in a military context. Well, that opinion changed rather quickly as t...

When Germany began looking in late 1915 for a new weapon ideally suited for the “last 200 meters” of a combat advance, Hugo Schmeisser’s blowback submachine gun would prove to be the weapon that would set the standard for virtually all submachine guns to come. It was a fully automatic only weapon...

The MP35 submachine gun was designed by Theodore Emil Bergmann, the son of the Theodore Bergmann who had manufactured the turn of the century line of Bergmann pistols. Unlike his father, Emil was a firearms designer, and not just a manufacturer. This design was submitted for German military testi...

Most people think that the MP41 is simply an MP40 in a wooden stock, but this is actually not the case - and unlike the MP40, the MP41 can be accurately called a Schmeisser - because it was Hugo Schmeisser who designed it.

The MP41 is actually a combination of the upper assembly of an MP40 wi...

The MAT-49 was developed by France after World War Two to satisfy the need for a more modern submachine gun to replace the MAS-38. The military had come around to standardizing on the 9x19mm cartridge for its pistols and subguns, and the 7.65mm MAS-38 was not feasible to convert. All three state ...

The PM9 was an interesting an unique submachine gun designed by Louis Debuit for the French firm Merlin and Gerin (hence the MGD name – Merlin, Gerin, Debuit) in the late 1940s and early 50s. The design was intended to provide a very compact package, which it did with a very short action, folding...

The MP40 is an iconic piece of World War 2 weaponry, and it's about time we took a closer look at its development...

Thanks to the Institute of Military Technology for allowing me to have access to these three examples so I can bring them to you! Check out the IMT at:

The MP40/I was an experimental modification of the MP-40 submachine gun developed by the Erma company (we think) in late 1942. It was presumably developed in response to complaints of Soviet fire superiority with SMGs because of their large drum magazines (and also the larger number of SMGs used ...

Today, we have a chance to take a look at a suppressed M3 "Grease Gun", as purchased and issued by the Office of Strategic Services (the OSS; predecessor to the CIA). Thanks to its readily removable barrel, the M3 (and M3A1) submachine gun was an easy gun to adapt to use with a suppressor (or as ...

Great Britain was one of the few countries that went into World War Two with virtually no submachine gun development. Not every country had an issued SMG by 1939, but virtually everyone had at least been working on experimental concepts - except the British. It was only with the outbreak of hosti...

The kp/31 Suomi submachine gun in Finnish service was an outstanding weapon, but it was slow and expensive to manufacture. When Finnish forces began capturing Soviet PPS-42 and PPS-43 submachine guns form the Soviets in the Continuation War, it was very quickly decided that Finland should copy th...

The kp/31, aka M31 "Suomi" submachine gun was adopted by the Finnish Army in 1931. It was produced by the Tikkakoski company (more commonly known today as Tikka), and in addition to Finnish military contracts they were eager for international sales, either commercial or military. To that end, the...

The American 180 is a .22 rimfire submachine gun that fires at 1200-1500 rounds per minute or more, and feeds from drums of 177 to 275 rounds capacity. While it makes a great recreational machine gun, it was actually initially developed with law enforcement sales in mind. The notion was that the ...

Shortly after the end of World War Two, Yugoslavia adopted a submachine gun that looked very much like the Soviet PPSh-41, and was obviously inspired by it. However, the manufacturing methods were completely different, with the Yugoslav gun being of all milled construction and with internal parts...

The Yugoslav M49/57 submachine gun looks very similar to the Soviet PPSh-41, but it constructed quite differently, and has a much larger recoil spring. The question is, how will it shoot? Will it be fast and controllable like the Papasha or slower like the Sudayev?

Thanks to Marstar for lettin...

In order to circumvent Versailles Treaty restrictions on arms manufacture, the German Rheinmetall firm purchased a small Swiss company called Solothurn Waffenfabrik in 1929, allowing it to route its business through Switzerland instead of Germany. One of its first products was the S1-100 submachi...

George Hyde designed the gun that would eventually be adopted as the M2 submachine gun in the late 1930s, and it was first tested at Aberdeen Proving Grounds in October of 1939. At that time, the gun had many good traits (weight, handlings, etc) but suffered from parts breakage and unreliability....

The Star Z-70B was an incremental improvement on the earlier Z-62 and Z-63 submachine guns adopted by the Spanish military and security services. It remains an open bolt, selective fire design, with an underfolding stock. The trigger has changed from a progressive type to a standard trigger with ...

Designed by Aimo Lahti, the Suomi m/31 submachine gun is in my opinion one of the standout submachine guns of the World War Two era. Despite its hefty weight (10.4lb / 4.7kg) and lack of a good pistol grip stock, it still manages to be tremendously controllable and accurate, with a very high rate...
