The Germans had already noted the Russian success with machine pistols (submachine guns). The major shortcoming of the machine pistol was that it was, in fact, a pistol with a longer barrel and a larger magazine (thirty or more rounds). Despite the longer barrel, the pistol cartridge lacked accuracy, even when fired from the hip in bursts of automatic fire. The pistol cartridge also lacked punch. Where a rifle bullet would kill a man, a pistol round would only wound. And the wounded soldier would often keep firing back. The assault rifle round (beginning with the MP-43/StG-44) was not quite as powerful as the standard rifle round, but more powerful than a pistol round. This made a big difference for the infantry, as the assault rifle could be fired at longer ranges with more accuracy and stopping power.
