| Notes | The PPD-34 (Pistolet-Pulemyot Degtyaryova) was sub-machine gun which was first issued in 1935. It was a robust design, but was never fully adopted by the military, as the Soviet high command saw them as a waste of ammunition, so few were made and those that were issued were mainly used by secret police. An improve version was issued in 1939, which allowed for the use of a 71 round drum, but this too was never fully appreciated. It was during the war with Finland that the need for a sub-machine became apparent, as Finish troops armed with the Suomi had an advantage in close range fire fights and this forced the Soviets to re-think and finally adopt a modified version and these were issued as the PPD-40. It was issued mainly to NCOs, but because the PPD used no stamped parts, it meant that it was a costly weapon to produce and this made the Soviets look for a cheaper and improved design, which came in the shape of the PPSh. |
