Pearce Grip
The Pearce Grip PGFI20SF is a grip frame insert designed specifically for Glock 20SF and 21SF pistols. This polymer plug fills the bottom rear cavity of your frame—an opening that comes empty from the factory on many Glock models. It's a simple, effective way to seal that gap, keep your pistol cleaner, and improve how your magazines seat in the well.
If you've ever noticed dirt, dust, or debris working into the frame cavity of your Glock, or if you just prefer a finished look without that hollow opening, this insert solves both problems. The front lip creates a smooth, flush interface with the magazine well to ensure reliable feeding and a professional appearance. Installation is straightforward—the insert uses the lanyard hole for retention and snaps firmly into place without tools or permanent modification.
This is a quality-of-life upgrade for shooters who maintain their gear and want to eliminate unnecessary openings where contamination can hide. It doesn't increase magazine capacity or alter your pistol's function; it simply seals and protects. The black polymer construction matches standard Glock finishes and is built to handle the rigors of range use, training, or duty carry.
