According to the principle of action, PPS-43 refers to samples of automatic weapons with a free bolt. The mass of the shutter and the force of the reciprocating spring are in such a ratio with the mass of the bullet, the length of the barrel and the pressure of the powder gases that at the time of the shot the reliability of locking the bore is provided without a special locking mechanism. The manufacturability of the design is ensured through the widespread use of stamping and spot welding. For the manufacture of PPS-43 it took 3 times less time (1.8-2 machine hours) and 2 times less metal than for PPSh-41.

The performance characteristics
The PPS-43 submachine gun is intended only for automatic fire, as it does not have a translator for single fire. Sights consist of a front sight and a sight with a rotating whole. The whole is designed for a range of 100 and 200 m, according to which the numbers 10 and 20 are set at the rear. The deadly power of the submachine gun bullet remains at a range of up to 800 m. The best results are achieved when shooting in short bursts (2-5 shots).
