I tend to think the Russians up until the AK-47 which even then was a rip off the the Sturmgewehr 44 had poor weapons, they just had a lot of them is all. But the PPSh-41 was a great sub-machinegun, it had a longer range than it's Axis and Allied counterparts, it packed great firepower, one round in the chest would most likely kill you with its high caliber rounds.
