Abstract: Improved gun with automatic loading of cartridges, comprising a cartridge loader in the form of a tubular magazine (4), characterized in that: The magazine bottom (18) is mounted in a way so that it can slide in the axial direction (X-X?) with respect to the tubular magazine (4). The sliding magazine bottom (18) is equipped with a shock absorber (26) able to absorb the shocks exerted on the magazine bottom (18) in the axial direction (X-X?) of the tubular magazine (4). The cartridge follower assembly (19) provided with a shock absorber (29) that can absorb the shocks exerted on the follower assembly (19) in the axial direction (19) of the tubular magazine (4).

Abstract: Shoulder fire arm comprising a frame a barrel and a stock for holding the weapon against the shoulder and or the cheek of the gunman wherein the stock is formed of a body and a recoil pad at the end of this body, the recoil pad being connected to the body of the stock by means of a shock absorber and the absorber is placed in such a way that during the shot the stock moves down from the shoulder and cheek of the gunman.
