Soviet PPD-40: Degtyarev's Submachine Gun
The PPD-40, designed by Vasily Degtyarev, was the first major Soviet submachine gun, initially influenced by the DP-27. Despite its accuracy and reliability, its complex, lathe-turned construction made it expensive. The PPD-40 saw significant development, notably adopting a drum magazine inspired by the Finnish Suomi M31, and was later replaced by the mass-producible PPSh-41.
