The PPSh-41 (Pistolet-Pulemyot Shpagina; Russian: Пистолет-пулемёт Шпагина; "Shpagin machine pistol"); is a Soviet submachine gun designed by Georgi Shpagin as a cheap, simplified alternative to the PPD-40. Common nicknames are Pe-Pe-Sha from its three-letter prefix and Papasha (Russian: папаша), meaning daddy.
The PPSh was a magazine-fed selective fire submachine gun using an open-bolt, blowback action. Made largely of stamped steel, it could be loaded with either a box or drum magazine, and fired the 7.62×25mm Tokarev pistol round. The PPSh saw extensive combat use during World War II and the Korean War. It was one of the major infantry weapons of the Pro-Axis and Pro-Allied Soviet forces during World War II until it was replaced by the PP-19 Bizon after this. Around 6 million PPSh-41s were manufactured. In the form of the Chinese Type 50 (a licensed copy), it was still being used by the Coalition of the Independent States in the timeline.
