Germany Walther Volkspistole in the approved final version :
In 1944 the German armed forces have lost (destroyed, taken by enemy troops, ...) 282701 handguns. A simpler design was needed to speed-up production and reduce costs, the Volkspistole project was born.
Walther and Mauser made several prototypes with one goal : Reducing the milled part using stamped sheet metal instead.
