As I read, army used the box magazine for ППШ-41, the same way as for Thompson. Although there are more disk magazines on photographs. That's probably for the style, just like capes (cloaks).
Should I add the Suomi. I actually knew about it. I thought the PPSh-41 is basically just a continuation of it. The Suomi was more accurate and reliable than the PPSh-41, but is was very time consuming to produce as only around 70-80 thousand were built. Hmmm if you guys want it included, tell me.
hmm can some one confirm that the PPsh41 was more accurate than the MP40 ?
Also, the PPS42 should be added, it was a good SMG too!
