Pearce Grip Magazine Extension for Shield Arms S15 Magazines – Glock 43X/48

The Pearce Grip magazine extension adds approximately 5/8" of gripping surface to Shield Arms S15 magazines for the Glock 43X and 48. This extension improves control and comfort for shooters with larger hands or those seeking a fuller, three-finger grip without adding magazine capacity. It eliminates pinky hang-off and provides a more secure purchase during recoil.

Constructed from impact-resistant polymer with a matte black finish that matches most factory frames. This is a drop-in installation requiring no gunsmithing—simply remove the magazine base plate, slide on the extension, and reassemble. The extension maintains the flush fit of the original magazine base while adding minimal length to the grip.
