Disclosed is a firearm configuration for a handgun. The firearm configuration is designed to reduce the recoil forces encountered by a user upon firing the weapon. It further includes a recoil plate that absorbs forces generated by the slide during firing. Recoil forces are reduced by lowering the firearm's center of mass and by aligning a recoiling mass with the user's arm and trigger finger. The firearm configuration further includes a locking block which prevents rotational and lateral movement of the barrel upon firing.

Because of a clearance between a barrel supporting member and a barrel, a rotational movement of the barrel is not always constant. Thus, trajectory of a bullet is misaligned. A counterweight 40 is located upper than a barrel 10, and rings 61, 62, which are support portions, are located nearer to the counterweight 40 than a gravity center of the barrel 10. Since the barrel 10 is located lower than the counterweight 40 and engaged with a lower surface side of a gear 30, when a bullet is shot and the barrel 10 is moved backward, a force to rotate the barrel 10 itself clockwise is imparted by a circular surface shape of the gear 30. The barrel 10 receives a force to be rotated clockwise from the gravity center position, the ring 61 and the ring 62, and the barrel 10 is in contact with the inner surface of the barrel supporting member 50. Thus, in spite of the existence of the clearance, the barrel 10 is not displaced in the barrel supporting member 50.

The present invention relates to firearms, especially to guns, and more particularly to a system for attenuating recoil, reducing muzzle climb and increasing accuracy. The invention provides a recoil attenuating mechanism that is an improvement on the well-known and widely used Browning tilting barrel system which is used mostly in semi-automatic pistols. The recoil attenuation is achieved by redirecting and manipulating the forces of the recoil of the slide of the pistol to a different axis than what is the norm on a regular Browning action, thus reducing muzzle climb substantially in addition to attenuating recoil, and therefore improving accuracy, recovery time, and controllability.

An automatic submachine gun for exploiting recoil, that includes a stock; a fixed barrel; a grip provided with an extractable butt; a bolt sliding in direction parallel to the longitudinal axis of the barrel inside the stock for locking the breech of the barrel; a device for recovering the recoil kinetic energy of the bolt; a hammer swinging in opposition and through the action of a spring actuator element between a cocked position and an uncocked position; a trigger assembly for the hammer; an opposing lever of the hammer for single shot fire; and an opposing lever of the hammer for continuous burst fire; a manual fire mode selector; an extractable magazine for loading cartridge ammunition; and a firing pin.

A system is disclosed for extending a recoil impulse of a gun. The system elongates the recoil impulse to spread the recoil energy over time and reduce felt (i.e., peak) recoil force. Although the system adds weight to a gun, the system reduces felt recoil beyond what is possible by simply adding weight to a gun by using an inertial weight on a spring to absorb and release energy. To prevent shaking, the inertial weight system is tuned to a gun so that the inertial weight hits a pair of stops at certain points in the gun's discharge action cycle.
