MP35
The MP35 was a blowback operated, selective fire SMG which fired from an open bolt. The weapon featured a non-reciprocating cocking handle placed at the rear of the receiver, which was operated in a similar fashion to bolt-action on a Mauser rifle. This involved the weapon carrier to manually pull the handle up, pull backwards, push forwards and lock back down. When the gun was then fired the cocking handle remained stationary. On the BMP32 the weapon featured a safety at the rear of the bolt (again in a similar location to the Mauser rifle). On both BMP34 and MP35 the safety was relocated to the left side of the receiver. The shooter could select the mode of firing by applying different pressure to the trigger - a short pull fired single shots; a long pull resulted in full automatic fire. Feed was from right side of the gun, with ejection to the left. In contrast to many other SMGs of the time the MP35's magazine was inserted from the right-hand side of the weapon. Early versions used proprietary magazines, the BMP35 used Schmeisser MP28-compatible magazines. The barrel was enclosed into tubular jacket with cooling slots and muzzle brake/compensator at the front.
