The MP-38 and MP-40 submachine guns were open-bolt, blowback-operated automatic arms. Fully automatic fire was the only setting, but the relatively low rate of fire allowed for single shots with controlled trigger pulls. The bolt features a telescoping return spring guide which serves as a pneumatic recoil buffer. The cocking handle was permanently attached to the bolt on early MP 38s, but on late production MP 38s the bolt handle was made as a separate part. It also served as a safety by pushing the head of handle into a separate notch above the main opening, which locked the bolt either in the cocked or forward position. The absence of this feature on early MP 38s resulted in field expedients such as leather harnesses with a small loop, used to hold the bolt in forward position
