DESCRIPTION OF THE CURRENT EMBODIMENT

[0021] An embodiment of the pistol of the present invention is shown and generally designated by the reference numeral 10.

[0022] FIGS. 1-4 illustrate the improved pistol 10 of the present invention. More particularly, the pistol has a frame 12, firing facility 14, safety device 16, actuator 18, safety-indicating element 20, and selector 22. In the current embodiment, the firing facility is connected to the frame and operable to discharge the pistol. The safety device is connected to the frame and has a safe condition in which discharge of the pistol is disabled and an operable condition in which discharge of the pistol is enabled. The actuator is responsive to the presence of the safety-indicating element. The actuator is operably connected to the safety device to control the condition of the safety device such that the safety device is in the safe condition when the safety-indicating element is absent and in the operable condition when the safety-indicating element is present. The selector is rotatably received in the frame so as to be connected to the frame. The selector is also operably connected to the safety device. The selector is movable between an enabled position in which the safety device is operably responsive to the presence and absence of the safety-indicating element, and a disabled position in which the safety device remains in the operable condition irrespective of the presence and absence of the safety-indicating element. This is accomplished by the selector being an elongated shaft having a cam 24 operable to limit the position of the safety device.

[0023] The frame 12 defines a magazine well 26. The pistol also includes a removable slide 42 connected to the frame 12. The removable slide is operable to reciprocate on the frame. The selector 22 is enclosed and rendered inaccessible for movement except when the removable slide is removed from the frame. In the current embodiment, the safety-indicating element 20 can be a user's grip hand 28, and the actuator 18 can be a grip safety 30. The safety-indicating element can also be a magazine 32 when the magazine is properly seated within the magazine well, and the actuator can be a magazine safety 34. The pistol can include a second safety device 36 associated with a second actuator 38, in which case the selector 22 is movable between at least three positions. At least a first one of the selector positions operates to disable both safety devices, a second selector position operates to enable both safety devices, and a third selector position operates to enable only one of the safety devices. Alternatively, at least a first one of the selector positions operates to disable both safety devices, a second selector position operates to enable only a first one of the safety devices, and a third selector position operates to enable only a second one of the safety devices. As another alternative, at least a first one of the selector positions operates to enable both safety devices, a second selector position operates to enable only a first one of the safety devices, and a third selector position operates to enable only a second one of the safety devices. To accomplish this, the selector has at least two different cam profiles (24, 40), each associated with a respective one of the safety devices. The portion of each cam profile that interacts with each safety device when the selector is in a selected position determines if each safety device is enabled or disabled. It should be appreciated that if the selector is positioned to disable one or both safety devices, the selector immobilizes the actuator associated with the safety device(s) to be disabled in the operable position to enable discharge of the pistol. This means the grip safety is retracted as if squeezed by the user's grip hand, and the magazine safety actuator is elevated as if a magazine is present and properly seated in the magazine well.

[0024] The pistol 10 can also be viewed as having a grip safety 30 responsive to the presence of a user's hand 28 on the grip 44 in a conventional firing position with the user's forefinger 140 on the trigger 104, and operable to disable discharge of the pistol except when a user's hand is present, a magazine safety 34 responsive to the presence of a magazine 32 and operable to disable discharge of the pistol except when a magazine is present and properly seated within the pistol's magazine well 26, and a selector 22 operably connected to the grip safety and the magazine safety and having a plurality of positions, each corresponding to a different permutation of grip safety and magazine safety settings. In the current embodiment, the selector has at least three positions. One of the permutations includes enabling both safeties. One of the permutations includes disabling both safeties. One of the permutations includes enabling one, but not the other, of the safeties.

[0025] Referring now to FIG. 2, the slide assembly 166 of the pistol 10 has a slide 42, barrel 46, extractor 48, extractor spring 50, striker 52, striker captor 54, striker return spring 56, striker spring 58, striker sleeve 60, chamber indicator 62, indicator spring 64, rear sight 66, sight fiber 68, rear sight springs 70, 3/3 2×⅜ dowel pin 72, M4×4 socket head screw 74, M3×20 button head screw, striker safety 78, striker safety spring 80, striker safety plunger 82, striker safety screw 84, slide cover 86, M3×6 button head screws, recoil spring guide 90, inner recoil spring 92, outer recoil spring 94, M12 retaining ring 96, spring bushing 98, M4×flathead screw 100, and hiviz tritium sight 102. The slide has a top 148, from 150, and rear 152. The slide cover is a molded plastic part that is bolted down to the top rear of the slide. The slide cover restrains the striker sleeve. The slide cover has serrated sides 170, 172 so the user can grip the slide cover easily with the user's forefinger 140 and user's middle finger 162 to pull the slide assembly 166 rearward to chamber a round. The slide assembly has a center of mass 164, which is forward of the center of mass associated with a conventional slide assembly to reduce to reduce muzzle flip from recoil force. This is accomplished because the slide cover replaces a conventional metal rear exterior portion of the slide, which is much heavier than the molded plastic slide cover. However, it should be appreciated that the slide is sufficiently long enough to have forward and rear rails to engage the frame. The front sight is attached to the top front of the slide.

[0026] Referring now to FIG. 3-5, the frame assembly 168 of the pistol 10 has a frame 12, trigger 104, trigger bushing 106, trigger spring 108, 3/3 2× 11/16 dowel pins 110, trigger bar 112, 3/3 2× 13/16 dowel pin 114, trigger bar spring 116, 2-56× 3/16button head screw 118, sear 120, sear spring 122, 3/3 2×⅝ dowel pin 124, magazine safety 34, magazine safety spring 126, ejector 128, grip safety 30, grip safety spring 130, selector 22, slide stop 132, slide stop snap 134, and slide stop snap spring 136. The selector is only accessible with the slide assembly 166 removed from the frame to prevent an inadvertent change of the selector's position. In the current embodiment, the pistol is sold with the selector in the position that enables both the grip safety 30 and the magazine safety 34. The user must deliberately remove the slide assembly from the frame and rotate the selector to change the selector's position to disable either safety should the user desire to enable tactical reloading, or if the user's hand is incapable of disengaging the grip safety. In the current embodiment, the selector is limited to three positions by the geometry of the cam profiles 24, 40 on the selector so that the user cannot disable just the grip safety.

[0027] FIG. 6 illustrates the improved slide cover 86 of the present invention. More particularly, the slide cover has a top 142, front 144, and rear 146. The rear sight 66 is attached to the top rear of the slide cover, and the chamber indicator 62 is attached to the top front of the slide cover. The chamber indicator indicates if a round is currently chambered within the barrel 46.

[0028] FIG. 7 illustrates an alternative embodiment of the improved slide cover 154 of the present invention. More particularly, the slide cover 154 can be used as a replacement for the slide cover 86. The slide cover 154 has a rear 156 forming a right wing 158 and a left wing 160. The wings enable a user who is unable to grip the serrated sides 170, 172 of the slide cover 86 with sufficient force to pull the slide assembly 166 rearward to chamber a round to still use the user's forefinger 140 and user's middle finger 162 to pull the slide assembly 166 rearward to chamber a round by engaging the wings. The slide cover 154 is only one example of numerous alternative slide covers that can be provided to enable different capabilities of the pistol 10. Alternative slide covers can include a red dot sight or another style of integrated rear sight. Alternative slide covers can have different types of serrated sides to provide different grip characteristics. Alternative slide covers can also be made in different colors to denote different capabilities of the pistol, user, or ammunition.

[0029] FIGS. 8A-D illustrate the improved trigger bar 112 of the present invention. More particularly, the trigger bar has two arms 174, 176, each of which terminates in an aperture 178, 180 at their forward ends 182, 184. The two arms are connected at their rear ends by a rear bar 186. The rear bar has two rearward protrusions 188, 190 and a forward protrusion 192 defining a slot 194. The trigger bar is initially formed as a planar element shown in FIG. 8A that is subsequently bent into the finished condition shown in FIGS. 8B-D. After bending, the rear bar has two upward facing protrusions 196, 198. In the current embodiment, the trigger bar has a maximum length of 65.5 mm and a length of 64.0 mm excluding the length of the rearward protrusions. The apertures have a diameter of 2.38 mm. The trigger bar has a maximum width of 19.5 mm. The slot has a width of 1.2 mm. The gap 200 between the two rearward protrusions has a width of 7.0 mm. The trigger bar has a material thickness of 0.64 mm. The use of two arms instead of the single arm associated with a conventional trigger bar greatly reduces the bending stresses in the contact areas, enabling a thin gauge material to be used. The trigger 104 is centered between the arms so the forces applied to both arms are equally balanced to avoid eccentric loads. The extremely thin gauge of the trigger bar material enables the overall width of the pistol 10 to be narrower than a conventional pistol to improve concealment. The extremely thin gauge of the trigger bar material also reduces the mass of the trigger bar, which enables the trigger to have reduced mass compared to a conventional trigger. The reduced mass of the trigger keeps the center of mass balanced to prevent the pistol from inadvertently firing if dropped. The reduced weight of the pistol compared to a conventional pistol also makes the pistol more attractive for carry.

[0030] While a current embodiment of a pistol has been described in detail, it should be apparent that modifications and variations thereto are possible, all of which fall within the true spirit and scope of the invention. With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.

[0031] Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
