A machine pistol is an autoloading pistol capable of fully automatic fire. The term can also be used to describe a stockless handgun-style submachine gun. The term is a calque of Maschinenpistole, the German word for submachine guns. Machine pistols were developed during World War I and originally issued to German artillery crews who needed a self-defense weapon that is lighter than a rifle but more powerful than a standard semi-automatic pistol. This concept would eventually lead to the development of the personal defense weapon or PDW. Today, machine pistols are considered special-purpose weapons with limited utility, with their original niche being filled with either the PDW, carbines, or simply more modern semi-automatic sidearms. Contributing to their already-fringe use, without a shoulder stock and training, machine pistols can be difficult to control for all but the best shooters.
A submachine gun (SMG) is a magazine-fed automatic carbine designed to fire handgun cartridges. The term "submachine gun" was coined by John T. Thompson, the inventor of the Thompson submachine gun, to describe its design concept as an automatic firearm with notably less firepower than a machine gun. As a machine gun must fire rifle cartridges to be classified as such, submachine guns are not considered machine guns.
The MP 40 is a submachine gun chambered for the 9×19mm Parabellum cartridge. It was developed in Nazi Germany and used extensively by the Axis powers during World War II.
The STEN is a family of British submachine guns chambered in 9×19mm which were used extensively by British and Commonwealth forces throughout World War II and the Korean War. They had a simple design and very low production cost, making them effective insurgency weapons for resistance groups, and they continue to see usage to this day by irregular military forces. The Sten served as the basis for the Sterling submachine gun, which replaced the Sten in British service until the 1990s, when it, and all other submachine guns, were replaced by the SA80.
The StG 44 is a German assault rifle developed during World War II by Hugo Schmeisser. It is also known by its early designations as the MP 43 and MP 44. The StG 44 was an improvement of an earlier design, the Maschinenkarabiner 42(H).
The Lanchester is a submachine gun (SMG) manufactured by the Sterling Armaments Company between 1941 and 1945. It is a copy of the German MP28/II and was manufactured in two versions, Mk.1 and Mk.1*; the latter was a simplified version of the original Mk.1, with no fire selector and simplified sights. It was primarily used by the Royal Navy during the Second World War, and to a lesser extent by the Royal Air Force Regiment. It was given the general designation of Lanchester after George Herbert Lanchester, who was charged with producing the weapon at the Sterling Armaments Company.
The MP 18 was a World War I-era submachine gun designed and manufactured by German arms maker Bergman Waffenfabrik. Introduced into service in 1918 by the German Army during World War I as the primary weapon of the Sturmtruppen, assault groups specialized in trench combat, it was arguably the first such weapon used in combat.
The Shipka is a 9mm Bulgarian submachine gun produced in 1996 by the Bulgarian company Arsenal. The name is a reference to the famous Shipka Pass, near Arsenal's Kazanlak headquarters, in the Balkans where Bulgarian volunteers and Russian troops defeated the Ottoman Empire during the Russo-Turkish War of 1877, thereby liberating Bulgaria. The Shipka was developed for the Bulgarian police and military.
The MP34 is a submachine gun (SMG) that was manufactured by Waffenfabrik Steyr as Steyr-Solothurn S1-100 and used by the Austrian Army and Austrian Gendarmerie and subsequently by units of the German Army and the Waffen SS, in World War II. An exceptionally well-made weapon, it was used by some forces well into the 1970s.
The PPD is a submachine gun originally designed in 1934 by Vasily Degtyaryov. The PPD had a conventional wooden stock, fired from an open bolt, and was capable of selective fire. It was replaced by the PPSh-41.
The PPSh-41 is a Soviet submachine gun designed by Georgy Shpagin as a cheaper and simplified alternative to the PPD-40. A common Russian nickname for the weapon is "papasha" (папа́ша), meaning "daddy", and it was sometimes called the "burp gun" because of its high fire-rate.
FBP is a 9 mm submachine gun originally developed from a design first conceived in 1940 by Gonçalves Cardoso, an officer of artillery in the Portuguese Army. The onset of World War II halted development of the weapon, which was further modified and put into production in 1948.
The 9×25mm Mauser is a cartridge developed for the Mauser C96 service pistol around 1904 by DWM. Mauser pistols in this relatively powerful caliber were primarily intended for export to Africa, Asia, and South America. The 9mm Mauser Export cartridge was produced specifically for Mauser pistols and carbines made from 1904 to 1914 and then later from approximately 1930 to 1945 for submachine guns chambered for this caliber.
The Erfurter Maschinenfabrik (ERMA) was a German weapons manufacturer founded in 1922 by Berthold Geipel. Prior to and during World War II it manufactured many firearms, including the Karabiner 98k, the MP40 and other submachine guns.
The M3 is an American .45-caliber submachine gun adopted by the U.S. Army on 12 December 1942, as the United States Submachine Gun, Cal. .45, M3. The M3 was chambered for the same .45 ACP round fired by the Thompson submachine gun, but was cheaper to mass produce and lighter, although, contrary to popular belief, it was less accurate. The M3 was commonly referred to as the "Grease Gun" or simply "the Greaser," owing to its visual similarity to the mechanic's tool.
The 7.65×21mm Parabellum is a pistol cartridge that was introduced in 1898 by German arms manufacturer Deutsche Waffen- und Munitionsfabriken (DWM) for their new Pistol Parabellum. The primary developers of the pistol cartridge were firearms designers Georg Luger and Hugo Borchardt, who developed the round from the earlier 7.65×25mm Borchardt while working at DWM.
The Maschinenkarabiner 42(H) or MKb 42(H) (machine carbine Model 1942 (Haenel)) was an early German assault rifle firing an intermediate round of World War II. Designed in 1940 – 1941 by Hugo Schmeisser working for C. G. Haenel Waffen und Fahrradfabrik, several thousand were made and the gun was used on the Eastern Front in 1943.
