Abstract: This invention is referred to the creation of a megnetomechanical or mechanical system of the recoil's reduction and hence of the gun-barrel's rebound reduction during the shooting time. This system is composed from the successive recoil springs (5) and (2) in cooperation with the cylinder (1), from a magnet (M), which pulls, on the one hand, the gun's slide (K), and on the other hand, to the cylinder (1) a reverse this time retrogression of these two retrogressive components, and from the recoil spring (3), which because of its position and size, operates as an inertia mechanism of the recoil's quick execution and reduction.
