PPS-43 Sudajev submachine gun

The PPS-43 submachine gun was a Soviet automatic firearm designed by Alexey Sudaev. It was intended primarily as an armament for airborne and tank units, where it was intended to replace the less storable and heavier Spagin PPS-41 submachine gun. It was also produced in the years after World War II and was used in many countries around the world.

Almost the entire Sudaev submachine gun was made of metal. Compared to the previous Spagin PPŠ-41 submachine gun, it is lighter, more compact and easier to handle. The material consumption was reduced by two times compared to the PSF model and the time required to produce one piece was reduced by three times. Pressing and welding technology is used extensively in this type. The upper body, barrel shell and muzzle brake were moulded from a single sheet of metal. A block of steel was inserted into the central part, into which the barrel was moulded. The barrel bore was chrome plated to prolong its life. At the front of the barrel were circular barrel cooling holes. A folding shoulder rest was attached to the rear of the breech housing. The pistol grip was made of wood in the first pieces, later it was made of black plastic. The very simple sight made of two differently heighted plates with notches is designed for shooting at distances up to 100 m and up to 200 m. The safety lever is located in front of the trigger reed. The segmented box magazine holds 35 rounds. The trigger mechanism allows only burst firing. Relatively low rate of fire - 500-600 rounds/min (700-900 rounds/min for the PPS-41 ) allowed firing single shots after practice.
