PPSh-41

The PPSh-41 (Pistolet-Pulemyot Shpagina; Russian: Пистолет-пулемёт Шпагина; "Shpagin machine pistol") was a Soviet submachine gun designed by Georgi Shpagin as an inexpensive, simplified alternative to the PPD-40. Intended for use by minimally-trained conscript soldiers, the PPSh was a magazine-fed selective-fire submachine gun using an open-bolt, blowback action. Made largely of stamped steel, it had either a box or drum magazine, and fired the 7.62x25mm pistol round. The PPSh saw extensive combat use during World War II and the Korean War. In the form of the Chinese Type 50 (a licensed copy), it was still in use in Vietnam with the Viet Cong as late as 1970.
