Pearce Grip Magazine Base Plate Features The Pearce Grip Magazine Base Plate adds a full inch of length to the base of compatible Glock magazines giving shooters with larger hands a more complete and secure grip. This extension does not alter the internal capacity of the magazine so shooters gain ergonomic benefit without giving up any rounds on board. Compatible across Glock 20 21 29 40 and 41 magazines chambered in 10mm and .45 ACP the base plate offers broad usability for owners running multiple Glock models. The one exception is the 10-round Glock 30 magazine which the extension is not designed to fit. Installation simply replaces the factory floor plate requiring no gunsmithing or special tools to complete. The finished black finish matches factory magazine hardware for a clean factory-look appearance once installed. This straightforward accessory gives shooters a meaningful ergonomic upgrade for a low cost and minimal effort. Glock owners running full-size or compact 10mm and .45 ACP pistols will find this base plate a worthwhile addition to their magazines.
