Duration: 12:21

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.

Quick Summary

The Soviet PPD-40 submachine gun, designed by Vasily Degtyarev, was the first major Soviet SMG.

Frequently Asked Questions

Who designed the Soviet PPD-40 submachine gun?

The Soviet PPD-40 submachine gun was designed by Vasily Degtyarev. It was his first major contribution to Soviet submachine gun development, building upon his earlier work with the DP-27 light machine gun.

What made the PPD-40 expensive to produce?

The PPD-40 was expensive and time-consuming to manufacture because it relied heavily on lathe-turned parts. This contrasted with later designs like the PPSh-41, which utilized stamped steel components for mass production.

What was the significance of the 'SA' marking on the PPD-40?

The 'SA' in a box stamp indicates the firearm was captured by the Finnish Army during conflicts like the Winter War or Continuation War. These captured weapons were often put back into service by Finnish forces.

How did the PPD-40's drum magazine differ from earlier versions?

The PPD-40 adopted a 71-round drum magazine design inspired by the Finnish Suomi M31. This drum fed directly into the receiver and required the stock to be split to accommodate its size.
