Seems like the funniest thing: you’d think that the Soviets, with their indifference to the lives of their own people, would have been arming cannon fodder with the cheapest guns. Instead, they had more of a conventional submachine gun as their standard weapon, as I understand it - and they specified chrome bores in their guns.Did the Russians have anything resembling the grease gun in their inventory?
The PPsh-41 was the standard issue Soviet sub machine gun. It was pretty primitive. With a 71 round drum magazine and a cyclic rate that could exceed 1000 rpm (depending on the ammo) it was pretty effective. They issued them to troops who rode into battle on top of tanks. About 6 million were made.
Captured ones were particular favorites of German troops. Some were even converted to 9mm and called the MP41. (the original cartridge was 7.62x25)
