ppd-40

The PPD-40 (Russian: Пистоле́т-пулемёт Дегтярёва, Degtyaryov machine pistol) is a Soviet submachine gun chambered in 7.62×25mm Tokarev, originally designed in 1934 by "Vasily Degtyaryov":[https://en.wikipedia.org/wiki/Vasily_Degtyaryov]. It had a conventional wooden stock without pistol grip, open bolt mechanism, and selective fire. It was replaced by the lower-cost PPSh-41. The later PPD models can utilize a 71-round drum magazine.
