9-mm Submachine Gun MP 34/I (Bergmann)

MP34 Bergmann Submachine Gun

This weapon is a development of the original German Bergmann machine pistol Model 1918. It was in wide use in the German Army and was also used extensively by U.S.S.R. It is the original of all blowback-type submachine guns and is the forerunner of practically every submachine gun manufactured today. It was adopted as the official submachine gun of the Swedish Army in 1937 and was widely distributed throughout Europe during the years immediately before World War II.

This weapon can be recognized by: (1) The cocking handle at the rear of the receiver; (2) the protruding magazine well on the right side of the receiver (on the Soviet Bergmann the magazine well on the left side of the receiver); (3) the automatic safety device placed behind the trigger to prevent firing of the weapon unless the cocking handle is locked down; (4) the cylindrical body tube which is threaded at the front end to receive the barrel and barrel jacket; and (5) the method of selective fire, i.e., slight trigger depression results in single fire, greater trigger depression results in full automatic fire.
