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 having a downwardly facing upper surface 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, the recoil mechanism further comprising a helical shape recoil spring defining a spring axis parallel to the bore axis, the helical shape defining a bore receiving a guide rod below the barrel and defining a guide rod axis below the level of the trigger guard upper surface; and
the recoil mechanism being entirely below the barrel and forward of the trigger finger space.
2. A firearms sear mechanism, the sear mechanism comprising:
a sear housing;
a sear block disposed in the sear housing, the sear block further comprising a disconnector receiving slot;
a sear operably mounted on the sear block; the sear further comprising a cam; a sear bias spring operably attached to the sear;
a disconnector operably installed in the sear block disconnector receiving slot; the disconnector further comprising a cam;
a striker block actuator disposed in the sear block adjacent to the disconnector cam and operably interactive with a striker block; and
a striker block operably actuated by the striker block actuator.
3. A firearms sear comprising
a first lateral side;
a distal sear portion;
a proximate cam portion;
a cam located at the proximate cam portion and on the first lateral side;
a ledge portion adjacent to the cam on the proximate cam portion; and
a bias spring attachment portion between the cam portion and the sear portion.
4. A firearm comprising a 1911-type trigger and a sear assembly having a rotational sear and a sear block actuated by the 1911-type trigger wherein rotation of the sear is isolated to the sear block.
5. A trigger assembly for a firearm, the trigger assembly comprising:
a trigger safety having a cam;
a trigger housing piece housing a spring optionally actuatable by the cam, and a top piece actuated by and disposed on top of the spring; and
a trigger yoke connected to the trigger housing.
6. A trigger safety assembly for a firearm, the firearm comprising a housing or insert and wherein the safety assembly comprises an integral trigger safety having a vertical stop surface, such that the vertical stop surface operably interacts with the housing or insert.
7. The firearm of claim 6, wherein the right-handed manual safety assembly and left-handed manual safety assembly are independently and selectively actuatable by an end user.
8. A translational yoked trigger for a firearm, the translational yoked trigger comprising an integral trigger safety.
9. An insert for a recoil spring of a firearm, the insert comprising:
a main body portion that fits inside the tunnel formed by coils of the recoil spring, the main body portion having a proximate end; and
an end piece on the proximate end of the main body portion, the end piece being adapted to selectively secure the recoil spring to the firearm.
10. A firearm comprising:
a recoil spring having coils and comprising a tunnel formed by the coils of the spring;
a recoil spring insert disposed in the tunnel, the insert further comprising:
a main body portion that fits inside the tunnel, the main body portion having a proximate end, wherein the main body portion defines a horizontal plane;
an end piece on the proximate end of the main body portion wherein at least a portion of the end piece extends perpendicular to the horizontal plane of the main body portion; and
a grip insert shaped to provide a slot to receive the perpendicular portion of the end piece of the recoil spring insert, whereby the end piece selectively engages or disengages with the slot.
11. A firearm comprising:
an insert;
a cam pin housed proximate the barrel in the insert;
a barrel connected to the insert and defining a bore axis, the barrel having a forward tubular portion having a lower wall surface portion;
36
a slide enclosing the barrel and operable to reciprocate along the bore axis between a forward battery position and a rearward open position; and
a cam channel defined by a rear portion of the barrel and having an upper portion above the level of the lowest portion of the forward tubular portion of the barrel, the cam channel receiving the cam pin, the cam channel further 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.
12. A firearm comprising:
a trigger guard;
an insert above the trigger guard;
a barrel connected to the insert and defining a center line axis;
a slide enclosing the barrel and operable to reciprocate along the center line axis between a forward battery position and a rearward open position;
an arrangement of cams, lugs, and a pin, the arrangement connected to the barrel, wherein the cams and lugs engage and disengage with each other and the pin as the barrel moves in and out of battery.
13. The firearm of claim 12, wherein one or more of the cams of the arrangement of cams, lugs and a pin, are connected to the insert.
14. A trigger assembly for a firearm, the trigger assembly comprising:
a trigger safety having a cam;
a trigger housing piece housing a spring optionally actuatable by the cam, and a top piece actuated by and disposed on top of the spring; and
37
a trigger yoke connected to the trigger housing.
15. A translational yoked trigger for a firearm, the translational yoked trigger comprising an integral trigger safety.
16. A firearm having a barrel assembly, the barrel assembly comprising:
a forward tubular portion having a lower wall surface portion and defining a bore axis;
an insert housing a cam pin proximate the barrel;
a rear portion of the barrel defining a cam channel receiving a cam pin;
a 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.
17. A firearm slide, the firearm having a slide portion and a rail portion, the slide comprising a
plurality of serrations, the serrations being configured to maximize the thickness of the slide portion in the slide rail portion along which rail portion the slide moves translationally.
18. A firearm having a user-configurable manual safety system, the system comprising:
a bore having a right side and a left side;
a right-handed manual safety assembly installed in the right side of the bore; and
a left-handed manual safety assembly installed in the left side of the bore.
19. The firearm of Claim 18, wherein a manual safety assembly is installed on one side of the bore and a plug is installed on the other side of the bore.
20. A chassis insert for a firearm, the insert configured to be operational in more than one type of firearm to provide a multi-functional piece usable across firearm platforms.
