The Danish Madsen M/50 submachine gun is an updated version of the M/46 that preceded it, developed and manufactured post World War II. This model is manufactured using two separate stamped steel receiver halves hinged at the rear of the receiver and held together at the front by the barrel nut, purposefully designed to allow easy access for maintenance. For disassembly, the barrel nut is able to be unscrewed by hand, allowing the left side of the receiver housing to open, with all the internal components remaining in the right half. The hollow pistol grip contains a magazine loading tool. Although it seems very unconventional, it proved to be an extremely reliable and accurate submachine gun. This model was originally demonstrated for military testing in Canada in November 1950 that was also witnessed/attended by representatives from Britain, the U.S. Army, and Denmark. In that test, a single M/50 successfully test fired over 20,000 rounds of ammunition in a little over 2 1/2 hours with no failures. As noted, it uses many stamped steel parts except for the barrel and bolt, both of which are machined. It has a right side folding tube type stock, grip safety behind the magazine well, and left side mounted sling swivels. Blade front and fixed peep rear sight. With an extra folding stock with a leather cover.
