Pearce Grip Frame Insert for Gen4 Glock 21/41

The Pearce Grip Frame Insert eliminates the gap between the grip and magazine on Gen4 Glock 21 and 41 pistols. This insert fills the void created when using magazines without the finger groove cutout, providing a flush fit and preventing debris from entering the magazine well. Shooters who prefer older-style Glock magazines or aftermarket options without the Gen4 groove will find this insert restores a clean, seamless grip profile.

Constructed from durable polymer, the frame insert installs in seconds without tools or modification. Simply slide it into the magazine well cavity until it seats firmly. The low-profile design maintains the factory grip texture and does not interfere with magazine changes or grip angle. No gunsmithing required—this is a true drop-in upgrade for anyone running non-Gen4-grooved magazines in their Gen4 large-frame Glock.
