PPSh-41
The PPSh-41 (Russian: Пистоле́т-пулемёт Шпа́гина-41, romanized: Pistolét-pulemyót Shpágina-41, lit. 'Shpagin's machine-pistol-41') is a selective-fire, open-bolt, blowback submachine gun that fires the 7.62×25mm Tokarev round. It was designed by Georgy Shpagin in the Soviet Union to be a cheaper and simplified alternative to the PPD-40.
