Abstract

The subject matter described in this specification relates generally to a firearm recoil compensation system and a process for manufacturing a firearm recoil compensation system. The recoil compensation system includes a barrel, a compensator, and a slide. The compensator is attached to a muzzle end of the barrel. The compensator includes a projection extending along an upper surface of the barrel in a direction away from gas ports in the compensator. The slide is configured to house the barrel, and a slot is defined in an upper surface of the slide, where the slot is shaped to allow the slide to, at least partially, wrap around the projection of the compensator with the slide in a battery position.

Claims (34)

1. A firearm comprising:

a frame;

a barrel;

a compensator attached to a muzzle end of the barrel, the compensator comprising a projection extending along an upper surface of the barrel and in a direction away from the muzzle end of the barrel;

a slide slidably coupled to the frame and housing the barrel, wherein a slot is defined in an upper surface of the slide and the slot is shaped to allow the slide to, at least partially, wrap around the projection with the slide in a battery position; and

a sight mounted to an upper surface of the projection.

2. The firearm of claim 1 , wherein the upper surface of the slide is substantially flush with the upper surface of the projection.

3. The firearm of claim 1 , wherein side surfaces of the compensator are substantially flush with side surfaces of the slide.

4. The firearm of claim 1 , wherein the compensator comprises a gas port defined within the upper surface of the compensator.

5. The firearm of claim 4 , wherein the sight is spaced apart from and rearward of the gas port.

6. The firearm of claim 1 , wherein the compensator comprises a gas port defined within the upper surface of the compensator, a gas port defined within each of a right side surface and a left side surface of the compensator.

7. The firearm of claim 1 , wherein the slot is shaped to allow the slide to completely surround the projection.

8. The firearm of claim 1 , wherein the compensator and barrel are machined together from a single piece of metal.

9. The firearm of claim 1 , wherein the compensator is threaded on the barrel.

10. The firearm of claim 1 , wherein a portion of the frame extends around a bottom portion of the compensator.

11. The firearm of claim 10 , wherein a front surface of the frame is substantially flush with a front surface of the compensator.

12. The firearm of claim 1 , wherein the upper surface of the slide is substantially flush with the upper surface of the projection, and

wherein side surfaces of the compensator are substantially flush with side surfaces of the slide, and

wherein a front surface of the frame is substantially flush with a front surface of the compensator.

13. A firearm recoil compensation system comprising:

a barrel;

a compensator attached to a muzzle end of the barrel, the compensator comprising a projection extending along an upper surface of the barrel and in a direction away from gas ports in the compensator; and

a slide configured to house the barrel, wherein a slot is defined in an upper surface of the slide and the slot is shaped to allow the slide to, at least partially, wrap around the projection with the slide in a battery position.

14. The system of claim 13 , further comprising a sight mounted to an upper surface of the projection.

15. The system of claim 13 , wherein the upper surface of the slide is substantially flush with the upper surface of the projection, and

wherein side surfaces of the compensator are substantially flush with side surfaces of the slide.

16. The system of claim 13 , wherein the compensator comprises a gas port defined within the upper surface of the compensator.

17. The system of claim 16 , further comprising a sight mounted to an upper surface of the projection and wherein the sight is spaced apart from and rearward of the gas port.

18. The system of claim 13 , wherein the compensator comprises a gas port defined within the upper surface of the compensator, a gas port defined within each of a right side surface and a left side surface of the compensator.

19. The system of claim 13 , wherein the slot is shaped to allow the slide to completely surround the projection.

20. A method of manufacturing a firearm compensation system comprising:

attaching a compensator to a muzzle end of a barrel, the compensator comprising a projection, wherein the compensator is attached such that the projection extends along the barrel and in a direction that is away from gas ports in the compensator and towards a chamber end of the barrel;

installing the barrel in a slide, wherein a slot is defined in an upper surface of the slide and the slot is shaped to allow the slide to, at least partially, wrap around the projection with barrel fully inserted in the slide; and

mounting a front sight to an upper surface of the projection.
