## Title
Shock, muzzle jump, and felt recoil reducers for handguns

## Abstract

Slip-on handgun grips which contribute to accuracy and speed of target acquisition and make shooting a handgun a more pleasant experience by providing a comfortable, secure grip; and by isolating a shooter's thumb from impact and reducing shock, muzzle jump, twist, and recoil when the handgun is fired. The grip is fabricated from a stretchable elastomeric material. This material plus breakaway technology, external grooving, and a thumb-isolating tab maximize the enumerated benefits.

None of the devices disclosed in the foregoing patents are designed to reduce shock, muzzle jump, or felt recoil when the handgun equipped with the device is fired.
SUMMARY OF THE INVENTION
Disclosed and claimed herein are novel handgun grips which are improvements over those disclosed in the above-cited prior art in that they are specifically designed to provide a secure grip and to make a handgun more comfortable to shoot by reducing shock, muzzle jump, and recoil when a handgun equipped with such a grip is fired. Among the features which further these objectives are an ear (or tab) which protects the shooter's thumb when the gun is fired, external grooving, and inner side, breakaway nodes at the rear of the grip.



DESCRIPTION OF THE DRAWINGS
FIG. 1 is a pictorial view of a pistol equipped with a grip embodying the principles of the present invention;
FIG. 2 is an exploded view of the FIG. 1 pistol and grip;
FIG. 3 is a perspective view of the FIG. 1 grip;
FIG. 4 is a section through the FIG. 1 grip, taken substantially along line 4-4 of FIG. 3;
FIG. 5 is a rear end view of the FIG. 1 grip;
FIG. 6 is an exploded view of a revolver and a grip for that revolver; the grip embodies the principles of the present invention;
FIG. 7 is a partial perspective of the FIG. 6 grip; shown in this figure is a peel strip partially dislodged to show adhesive provided to secure the grip to the revolver;
FIG. 8 is a view similar to FIG. 6 but with the peel strip completely removed; and
FIG. 9 is a partial side view of the revolver and the grip; the grip is sectioned to show how it fits on and is secured to the revolver.



DETAILED DESCRIPTION OF THE INVENTION
Turning now to the drawings, FIG. 1 depicts a pistol 20 equipped with a slip-on grip 22 which is constructed in accord with the principles of the present invention; which provides a comfortable, secure grip; which isolates the shooter's thumb from the pistol's hammer guard; which is capable of reducing shock, muzzle jump, and felt recoil when pistol 20 is fired; and which keeps the pistol from twisting when it is fired, all contributing to accuracy and faster target acquisition.
Grip 22, best shown in FIGS. 2-5, has a sleeve 24, which fits over the butt 26 of pistol 20. An integral tab 28 extends from the upper end 30 of sleeve 24.
Grip 22 is fabricated from a stretchable, elastomeric material such as NAVCOM®. Upon being slipped onto pistol butt 26 (see arrow 32 in FIG. 2), the elastomeric material relaxes, ensuring that grip 22 stays in place. By virtue of its elasticity, grip 22 can be installed on a variety of pistols. For example, a single grip embodying the principles of the present invention fits full-frame semi-automatic, Beretta, FN Herstal, Glock, Heckler & Koch, Magnum Research, Ruger, Sig, and Tauras pistols.
An array 34 of inwardly extending impact nodes 36 is provided on the inner side of the sleeve's rear wall 38. When pistol 20 is fired, these nodes progressively collapse. This tuned progressive resistance, known as break-away technology, provides maximum reduction of felt recoil, minimizing recoil-attributible pain and discomfort and making pistol 20 comfortable to shoot.
Horizontal, non-slip grooving 40 on the exterior surfaces of sleeve 24 side walls 42 and 44, front wall 46, and rear wall 38 keeps shooter's hands from slipping even when grip 22 is wet.
The integral, upstanding tab (or ear) 28 identified above extends over the hammer guard of pistol 20 and protects a shooter's thumb by insulating the thumb from hammer guard contact during recoil, The array of impact nodes 36 extends over the inner side of tab 28 and makes a major contribution to the protective properties of that tab.
Referring still to the drawing, FIGS. 6-9 depict a revolver 60 equipped with a grip 62, which also embodies the principles of the present invention. Grip 62 is similar to above-described pistol grip 22, and it has the same constructions and functions and provides the same benefits. It is installed by slipping it onto the butt 64 of pistol 60 (see arrow 66, FIG. 6).
Components of grips 62 and 22 which have like properties and functions are identified by the same reference characters.
The upstanding tab 68 of revolver grip 62 differs from the corresponding component 28 of pistol grip 22 in that there is a layer 70 of adhesive on the inner side of tab 68 (see FIG. 7). The adhesive layer is covered by a peel strip 72.
After grip 62 has been slipped onto pistol butt 64, peel strip 72 is removed (see FIG. 8), and the tab is pressed against the frame 74 of pistol 60 (see FIG. 9). This further insures that grip 62 remains securely in place.
The principles of the present invention may be embodied in forms other than those specifically disclosed above and in the drawings. Therefore, the present embodiments are to be considered in all respects as illustrative and not restrictive, the scope of the invention instead being indicated by the the appended claims rather than by the foregoing description and the drawings; and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.

## Claims

wherein there is:
an integral, upstanding tab extending from the upper end of the handgun grip; and
a grip-securing adhesive on a handgun-facing side of the tab.
