They also had adopted a 10 round detachable box mag rifle by 1938(updated in 1940 to the SVT-40) that was intended for general infantry use, it was just impossible to replace Mosin Nagant production lines with SVT production lines in time.
Similarly the PPSh-41 was technically supplanted by the PPS-43, but it was more practical to keep all current PPSh-41 production lines open, because the PPS-43 was simplified enough for production that factories and workshops that could not have produced the PPSh could instead produce the PPS-43 with no problems.
Also just remembered they had mass produced rifle suppressors paired with subsonic ammunition, which the Germans couldnt rival because they had no rubber to spare.
