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 including a trigger guard having a downwardly facing upper surface defining a trigger finger space;

a selectively removable barrel connected to the frame and defining a center line axis, the barrel further comprising recesses with cam channels that are defined in a pair of opposed lateral side portions of the rear/breech portion of the barrel, and have 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 channels;

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, the recoil mechanism further comprising a bore receiving a guide rod and defining a guide rod axis, wherein the guide rod axis is below the upper surface of the trigger space; and

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

2. The firearm of claim 1 wherein the recoil mechanism is a spring.

3. The firearm of claim 1, further comprising a selectively removable takedown pin abutting the barrel forward of the trigger guard and positioned to selectively retain the selectively removable barrel from being removed when the takedown pin is in position.

4. A firearm comprising:

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

wherein the frame has a trigger defining a horizontal trigger plane vertically centered in a trigger guard;

wherein the frame has a forward lower surface forward of the trigger guard and positioned at a level below the trigger plane; and

a selectively removable barrel connected to the frame and defining a bore axis, the barrel further comprising recesses with cam channels that are defined in a pair of opposed lateral side portions of the rear/breech portion of the barrel, and have 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 channels;

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.

5. The firearm of claim 4 further comprising a selectively removable takedown pin abutting the barrel forward of the trigger guard and positioned to selectively retain the barrel from being removed when the takedown pin is in position.

6. The firearm of claim 4 wherein the forward lower surface is positioned at a level above a bottom portion of the trigger guard by less than 0.25 inch.

7. A firearm comprising:

a frame including a trigger guard having a downwardly facing upper surface defining a trigger finger space;

a selectively removable barrel connected to the frame and defining a center line axis, the barrel further comprising recesses with cam channels that are defined in a pair of opposed lateral side portions of the rear/breech portion of the barrel, and have 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 channels;

a selectively removable takedown pin abutting the barrel forward of the trigger guard and positioned to selectively retain the selectively removable barrel from being removed when the takedown pin is in position;

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, the recoil mechanism further comprising a bore receiving a guide rod and defining a guide rod axis, wherein the guide rod axis is below the upper surface of the trigger space; and

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