Pearce Grip Grip Extension Features The Pearce Grip Grip Extension is purpose built for Shield Arms 15 round magazines used in Glock 43X and 48 pistols replacing the factory magazine floor plate with a part designed for better handling. It adds approximately 5/8 inch of additional length to the magazine giving the shooter s pinky finger a place to rest rather than curling under the magazine base. This added length improves control and comfort during firing without altering the capacity of the Shield Arms 15 round magazine in any way. Because the extension is matched specifically to Shield Arms magazines it will not fit factory Glock magazines which require a different Pearce Grip part. The extension incorporates the same factory texture pattern found on the original magazine keeping a consistent feel across the grip and the extension. An ergonomic curve is built into the design for a more natural comfortable grip during both shooting and reloading. Made from high impact polymer the extension holds up to repeated use and the stresses of daily carry. Works on all generations of Shield Arms 15 round magazines for the Glock 43X and 48 the Pearce Grip Grip Extension is a simple comfort upgrade available for sale at GrabAGun.
