Post WW2 Polish SMGs : PPS wz. 42/53, PPS wz.42, and PM wz. 41 made by the Łucznik Arms Factory in Radom. The Polish models are direct copies of the Soviet pistolet-pulemyot Shpagina and pistolet-pulemyot Sudaeva.
Czech “samopal” vz. 26 in 7.62 Tokarev, with the famous forward-slopped grip, showing how the Radom PM-63 Polish PDW compact is, and in the contrary what a beast the Radom PPS wz. 43/52 is. #pistolet-pulemyot
