Abstract: A fastener for fastening a unitary hand grip to a pistol having a butt frame section with downwardly extending front and rear butt portions that are interconnected at their lower ends by a foot portion. One embodiment of the fastener has a yoke straddling the foot portion of the butt section, a pin extending between the openings in the upper sides of the yoke above the foot portion, a roller on the pin, and a screw for attaching the bottom of the yoke to the bottom of the unitary hand grip. The upper sides of the yoke contain concave depressions or dimples around the pin openings and the pin is dimensioned to be flush with the side edges of the yoke. The inside of the unitary hand grip is close to the outer side edges of the yoke and the concave depressions plus the length of the pin and the nearness of the wall of the hand grip prevent the pin from being dislodged from the yoke, even by heavy use of the pistol or from other shocks encountered in use.

Abstract: A fastener for fastening a unitary hand grip to a pistol having a butt frame section with downwardly extending front and rear portions that are interconnected at their lower ends by a foot portion. The fastener has a yoke with side members which straddle the foot portion of the butt section. Locking pawls formed at the upper ends of the side member permits insertion of the butt section between the yoke side members but serve to prevent withdrawal of butt section once inserted. The inside of the unitary hand grip is close to the outer surfaces of said socket members and prevent the opening of the locking pawls of the fastener when the unitary hand grip is installed.
