GRIP FORCE GEN 4 ADAPTER was developed specifically for GLOCK's GEN 4 series of pistols. It eliminates the drawbacks associated with
permanent modifications to your factory pistol. The GRIP FORCE GEN 4 ADAPTER mates completely to the back strap of the GLOCK frame, permitting the shooter's hand to conform to the frame in a more secure manner. This offers more control and allows the shooter to index the pistol on target more efficiently.
