Description
The OG-43 sported a very modern design, compared to its contemporaries. The receiver was made of stamped sheet metal, with the magazine serving as a grip. The bulk of the L-shaped bolt, along with the recoil spring, was housed in a cylinder directly above the barrel, which helped reduce muzzle climb when firing. The reciprocating cocking handle was located in the forward section of the bolt housing. The weapon was short-recoil blowback operated, and fired from an open bolt in both automatic and semi-automatic mode. Adjustable iron sights were fitted, with two possible settings for either 100m or 200m. Initially equipped with forward-folding metal stock, later production runs were fitted with simpler, wooden fixed stocks. It used the same double-stack magazines as the Beretta MAB 38, available in 10, 20, 30 or 40 rounds.
OG-44
The OG-44 version exhibited more traditional lines. It adopts the traditional wooden stock hinged to the pistol grip, positioned behind the trigger and the magazine well. It was slightly heavier than the OG-43, as well as the total length of 787 mm.
A machine pistol is an autoloading pistol capable of fully automatic fire, including stockless handgun-style submachine guns. The term is a calque of Maschinenpistole, the German word for submachine guns.
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 Uzi is a family of Israeli open-bolt, blowback-operated submachine guns and machine pistols first designed by Major Uziel "Uzi" Gal in the late 1940s, shortly after the establishment of the State of Israel. It is one of the first weapons to incorporate a telescoping bolt design, which allows the magazine to be housed in the pistol grip for a shorter weapon.
The STEN is a British submachine gun chambered in 9×19mm which was used extensively by British and Commonwealth forces throughout World War II and post war including the Korean War. The Sten was a simple design with very low production cost for mass production to meet demand for submachine guns.
The PP-19 Bizon is a 9×18mm Makarov submachine gun developed in 1993 by the Russian company Izhmash. The Bizon was designed by a team of engineers headed by Victor Kalashnikov and including Alexei Dragunov.
The Škorpion vz. 61 is a Czechoslovak machine pistol developed in 1959 by Miroslav Rybář (1924–1970) and produced under the official designation Samopal vzor 61 by the Česká zbrojovka arms factory in Uherský Brod from 1963 to 1979. The standard version uses .32 ACP ammunition.
The PM-63 RAK is a Polish 9×18mm submachine gun, designed by Piotr Wilniewczyc in cooperation with Tadeusz Bednarski, Grzegorz Czubak and Marian Wakalski. The RAK combines the characteristics of a self-loading pistol and a fully automatic submachine gun.
The CZ Model 23/25 was perhaps the best known of a series of Czechoslovak designed submachine guns introduced in 1948. There were four generally very similar submachine guns in this series: the Sa 23, Sa 24, Sa 25, and Sa 26. The primary designer was Jaroslav Holeček, chief engineer of the Česká zbrojovka Uherský Brod arms factory.
The MAB 38, Modello 38, or Model 38 and its variants were a series of official submachine guns of the Royal Italian Army introduced in 1938 and used during World War II. The Beretta Modello 38 was first issued to Italian police units stationed in Africa. The Italian army were impressed and decided to adopt a version to be used by elite troops and military police, but requested a modified variant which had no bayonet and a different recoil compensator. The MAB 38 was widely used and saw service on all fronts. The guns were also used by the German, Romanian, and Argentine armies of the time.
The Danuvia 39M/43M was a Hungarian submachine gun designed by Pál Király in the late 1930s and used during World War II.
The Jatimatic is a Finnish 9×19mm Parabellum submachine gun developed in the late 1970s and early 1980s by Jali Timari. The submachine gun made its debut in 1983. The Jatimatic was manufactured in very limited numbers initially by Tampereen Asepaja Oy of Tampere and later—Oy Golden Gun Ltd. The firearm was designed primarily for police, security forces and armored vehicle crews. It was never adopted into service by the Finnish Defence Forces, although the later GG-95 PDW version was tested by the FDF in the 1990s.
A telescoping bolt is a firearm bolt which telescopes over, that is, wraps around and past, the breech end of the barrel. This feature reduces the required length of a weapon such as a submachine gun significantly, and it allows compact designs to be balanced around the pistol grip in a way that gives "pointability" more like a pistol's.
The FMK-3 is a selective fire blowback-operated submachine gun of Argentinian origin designed by Fabricaciones Militares in 1974. Around 30,000 were produced for the Argentinian military by 1991.
The TZ-45 was an Italian blowback-operated submachine gun produced between 1944 and 1945, with an estimated 6,000 made.
The FNAB-43 is an Italian designed and developed submachine gun manufactured from 1943 to 1945. The first prototype was built in 1942 and the ~1,000 built by the FNA-B according to Ian McCollum of Forgotten Weapons were issued to German and Italian RSI units fighting in Northern Italy. The FNAB-43 was an expensive weapon to manufacture as it used extensive milling and precision engineering in its manufacture.
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, at the expense of accuracy. The M3 was commonly referred to as the "Grease Gun" or simply "the Greaser," owing to its visual similarity to the mechanic's tool.
Muzzle rise, muzzle flip or muzzle climb refers to the tendency of a firearm's or airgun's muzzle to rise up after firing. It more specifically refers to the seemingly unpredictable "jump" of the firearm's muzzle, caused by combined recoil from multiple shots being fired in quick succession. It has an adverse effect on maintaining accuracy with using automatic weapons or rapid-firing semi-automatic firearms, as a moving muzzle can throw off the shooter's aim, causing subsequent shots to miss the intended target.
The PPS is a family of Soviet submachine guns chambered in 7.62×25mm Tokarev, developed by Alexei Sudayev as a low-cost personal defense weapon for reconnaissance units, vehicle crews and support service personnel.
The Parinco mod. 3R is a submachine gun of Spanish origin that was designed in 1959. It is a selective-fire weapon for short-range street and brush fighting. It remains reasonably accurate up to 100 m using sighted semi-automatic fire. For close range combat, 2- or 3-shot bursts are recommended.
