Abstract

A semi-automatic pistol has a frame having a trigger guard defining a trigger finger space, a barrel connected to the frame and defining a bore axis, a slide connected to the frame and operable to reciprocate along the bore axis between a forward battery position and a rearward open position, a recoil mechanism operably connected between the slide and the frame, and operable to bias the slide to the battery position, and the recoil mechanism being entirely below the barrel axis and forward of the trigger finger space. The recoil mechanism may be a recoil spring defining a spring axis. The spring axis may be parallel to the bore axis. The recoil spring may be a helical shape defining a bore receiving a guide rod. The guide rod may be below the barrel. The trigger guard may have a downwardly facing upper surface defining the trigger finger space.

Claims

1. A firearm comprising:

a frame having a trigger guard defining a trigger finger space;

a barrel connected to the frame and defining a bore axis;

a slide connected to the frame and operable to reciprocate along the bore axis between a forward battery position and a rearward open position;

a recoil mechanism operably connected between the slide and the frame, and operable to bias the slide to the battery position; and

the recoil mechanism being entirely below the barrel and forward of the trigger finger space.

2. The firearm of claim 1 wherein the recoil mechanism is a recoil spring defining a spring axis, and wherein the spring axis is parallel to the bore axis.

3. The firearm of claim 2 wherein the recoil spring is a helical shape defining a bore receiving a guide rod, and wherein the guide rod is below the barrel.

4. The firearm of claim 2 wherein the trigger guard has a downwardly facing upper surface defining the trigger finger space, and wherein the guide rod defines a guide rod axis below the level of the upper surface.

5. The firearm of claim 4 wherein the entire guide rod is at a level below the upper surface of the trigger guard when the bore axis is horizontal.

6. The firearm of claim 1 wherein the frame has a trigger defining a horizontal trigger plane vertically centered in a trigger guard, and wherein the frame has a forward lower surface forward of the trigger guard and positioned at a level below the trigger plane.

7. The firearm of claim 6 wherein the forward lower surface is positioned at a level above a bottom portion of the trigger guard by less than 0.25 inch.

8. The firearm of claim 1 wherein the slide defines a forward barrel aperture, and defines a guide rod aperture below the barrel aperture, such that a guide rod connected to the frame may pass through the guide rod aperture as the slide reciprocates.

9. The firearm of claim 1 wherein the barrel has a forward tubular portion having a lower wall surface portion;

the frame including a cam pin proximate the barrel;

a rear portion of the barrel defining a cam channel receiving the cam pin;

the cam channel having a guide surface angled downwardly to the rear with respect to the bore axis, such that rearward movement of the barrel in recoil drives the rear portion of the barrel in a downward direction as the cam channel guide surface slides over the cam pin; and

the cam channel having an upper portion above the level of the lower wall surface portion of the forward tubular portion of the barrel.

10. The firearm of claim 9 wherein the cam channel is defined in a side portion of the rear portion of the barrel, and has a vertical floor surface spaced apart from a medial plane of the barrel, such that the barrel wall thickness is maintained above a preselected dimension proximate to the cam channel.

11. The firearm of claim 9 where each of a pair opposed lateral sides of the barrel defines a cam channel.

12. The firearm of claim 9 wherein the frame defines a pair of opposed upper sidewalls, each having an upper edge abutting the slide, and wherein at least a portion of the cam pin is above the level of the upper edges of the frame upper sidewalls.

13. The firearm of claim 9 including a pair of cam pins, each spaced apart from each other to receive a portion of the barrel therebetween.

14. A firearm comprising:

a frame;

a barrel connected to the frame and defining a bore axis;

a slide connected to the frame and operable to reciprocate along the bore axis between a forward battery position and a rearward open position;

the barrel having a forward tubular portion having a lower wall surface portion;

the frame including a cam pin proximate the barrel;

a rear portion of the barrel defining a cam channel receiving the cam pin;

the cam channel having a guide surface angled downwardly to the rear with respect to the bore axis, such that rearward movement of the barrel in recoil drives the rear portion of the barrel in a downward direction as the cam channel guide surface slides over the cam pin; and

the cam channel having an upper portion above the level of the lowest portion of the forward tubular portion of the barrel.

15. The firearm of claim 14 wherein the cam channel is defined in a side portion of the rear portion of the barrel, and has a vertical floor surface spaced apart from a medial plane of the barrel, such that the barrel wall thickness is maintained above a preselected dimension proximate to the cam channel.

16. The firearm of claim 15 where each of a pair opposed lateral sides of the barrel defines a cam channel.

17. The firearm of claim 15 wherein the frame defines a pair of opposed upper sidewalls, each having an upper edge abutting the slide, and wherein at least a portion of the cam pin is above the level of the upper edges of the frame upper sidewalls.

18. The firearm of claim 15 including a pair of cam pins, each spaced apart from each other to receive a portion of the barrel therebetween.

19. A firearm comprising:

a frame including a trigger guard;

a barrel connected to the frame and defining a center line axis;

a slide connected to the frame and operable to reciprocate along the center line axis between a forward battery position and a rearward open position;

a recoil mechanism operably connected between the slide and the frame, and operable to bias the slide to the battery position; and

the recoil mechanism being entirely below the upper edge of the frame and encapsulated entirely by the frame forward of the trigger guard.

20. The firearm of claim 19 wherein the recoil mechanism is a spring.
