Germany Adopts the PPSh in 9mm: the MP-41(r)
This video details the German MP-41(r), a conversion of the Soviet PPSh-41 submachine gun to fire 9mm Parabellum ammunition. Germany converted approximately 10,000 PPSh-41s to use standard MP-40 magazines and barrels for logistical reasons during WWII. The conversion involved a magazine well adapter and modifying MP-40 barrels to fit the PPSh trunnion.
