The United Defense M42 was an American submachine gun.
history
The M42 was created at the beginning of the Second World War. The design was originally from High Standard , while production was taken over by Marlin Firearms . The American military assessed the weapon as an alternative to the Thompson MPi . The first prototypes, which were still set up for the pistol standard caliber .45 ACP , were considered to be useful. Ultimately, however, an improved Thompson model was awarded, which was then introduced as the M1 in the United States Army .
However, the Dutch government in exile has shown interest. On his order, around 15,000 pieces in 9 mm Parabellum caliber were produced, but larger numbers were no longer delivered due to the occupation of the Dutch colonies in Indonesia. The remaining stocks were bought by the state-owned United Defense Supply Corporation and went to the Office of Strategic Services , which passed them on to resistance groups against the German and Japanese invaders worldwide. Copies for the Resistance, for example, were dropped over France by parachute. In Asia, Chinese national troops under Chiang Kai-shek received such weapons as military aid.
technology
The weapon was firing shut and only had an unlocked ground lock . In contrast to many submachine guns that were created in later years of the war, the construction was comparatively complex. The firing pin was designed as a single component and was not immediately integrated into the rapid bolt action. The cocking lever was not firmly attached to the closure and therefore did not move with it during the loading cycle. The opening in the housing for the lever was covered by a slider to protect against the ingress of dust. Due to a lack of demand and the use of labor-intensive machining processes, production was discontinued after the first order.
