The SIG MP-46 submachine gun was produced by SIG Schweizerische Industrie-Gesellschaft GmbH shortly after the World War Two, primarily for export. Among other countries it has been exported to Ethiopia. Design of the gun was based on the earlier SIG MP-41 and MP-44 submachine guns. It is a rare gun, which was produced for only a few years before being replaced in production by a more compact SIG MP-48 submachine gun of generally similar construction.
SIG MP-46 submachine gun features design solutions from both 1st and 2nd generations of submachine gun designs. Its wooden stock with semi-pistol grip is a heritage of pre-WW2 first generation designs, while its stamped steel barrel jacket and forend are reminiscent of second generation guns which appeared during the war.
SIG MP-46 submachine gun uses simple blowback action and fires from the open bolt, in single shots and full automatic modes. It does not have any dedicated manual safeties, instead relying on a folding magazine housing. When not in use, magazine housing can be folded forward and up, to lie below the barrel, protected from both sides by a forend. In this position, obviously, gun can not be fired at all. To commence firing, shooter has to press a magazine housing catch on the left side of receiver. This will release magazine, which then would rotate down to vertical (firing) position under its own weight, and lock there automatically. Other features include adjustable rear sight with settings for ranges between 50 and 300 meters, and double stack magazines holding 40 rounds of 9mm ammunition.
