Soviet SMGs produced by partisans
Interesting that PPD-40 was more expensive to produce than PPSH-41 ( 1 of the main reasons why it was replaced with PPSh-41 ), but PPD-40 was easier to produce in partisans conditions, because the main parts could be done from tubes of different diameter while PPSH-41 required stamp.
