US12710244 - Handgun slide with integral compensator

A slide for a semiautomatic handgun includes a slide body extending along a bore axis and having a top wall, side walls extending downward from lateral margins of the top wall, and a distal end defining a distal opening intersected by the bore axis. The slide body defines an open region between the top wall and the side walls, the open region sized and configured to receive a barrel of the semiautomatic handgun extending along the bore axis and so that a muzzle end of the barrel is spaced axially from the distal end of the slide body. A distal end portion of the top wall defines one or more ports positioned between the distal end of the slide body and the muzzle end of the barrel to be received in the open region.

handgunslidecompensatorsemiautomatic

The patent describes a semiautomatic handgun slide that incorporates an integral compensator, featuring a top wall with ports designed to vent gases from the barrel during firing. This design allows the barrel to be positioned rearward of the slide’s distal end, enhancing performance by reducing muzzle rise.

Claim 1

1 . A slide for a semiautomatic handgun, the slide comprising: a top portion extending along a bore axis; sides connected to and extending downward from the top portion; wherein the slide has a distal end portion that includes part of the top portion and the sides, the distal end portion having a distal end defining a projectile opening; wherein the slide defines an open region sized and configured to receive a barrel of the semiautomatic handgun along the bore axis so that a distal end of the barrel is spaced axially and rearward of the distal end of the slide; wherein a center of the projectile opening is vertically offset from the bore axis; and wherein the distal end portion of the slide defines one or more ports in the top portion, the one or more ports positioned between the distal end of the slide and the distal end of the barrel to be received in the open region, the one or more ports configured to vent a portion of gases exiting the barrel upon firing the handgun. a top portion extending along a bore axis; sides connected to and extending downward from the top portion; wherein the slide has a distal end portion that includes part of the top portion and the sides, the distal end portion having a distal end defining a projectile opening; wherein the slide defines an open region sized and configured to receive a barrel of the semiautomatic handgun along the bore axis so that a distal end of the barrel is spaced axially and rearward of the distal end of the slide; wherein a center of the projectile opening is vertically offset from the bore axis; and wherein the distal end portion of the slide defines one or more ports in the top portion, the one or more ports positioned between the distal end of the slide and the distal end of the barrel to be received in the open region, the one or more ports configured to vent a portion of gases exiting the barrel upon firing the handgun.
