This is my ppsh41 submarine gun and is dated 1944, I find this unusual as production of the pps43 was well under way and was much cheaper and faster to get out the door. Ppsh41 (Shpagin machine pistol"); is a Soviet submachine gun designed by Georgi Shpagin as a cheap, reliable, and simplified alternative to the PPD-40.
The PPSh is a magazine-fed selective fire submachine gun using an open-bolt, blowback action. Made largely of stamped steel, it can be loaded with either a box or drum magazine, and fires 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 Soviet Armed Forces during World War II. Around six million PPSh-41s were manufactured.
