Designed by Russian George Shpagin to meet a desparate need for firepower in the USSR following the invasion of Nazi Germany at the beginning of World War II. The gun uses a simple blowback action, and fires from the open bolt position. A very reliable weapon with a high rate of fire and large magazine capacity it was ideally suited to the close quarters house to house fighting at the battle of Leningrad. The drum magazines proved slow to refill in battle conditions so in 1942 the USSR developed a curved box magazine holding 35 rounds.
