A Pearce Grip PGGFI Black Grip Frame Insert for Glock Full Size Models plugs a functional gap in your pistol's design. This simple but effective accessory fills the bottom rear cavity of full-size Glock frames, sealing an opening that Glock leaves behind the trigger guard. Beyond aesthetics, the insert serves a practical purpose: its forward lip creates a snug, flush fit with the magazine well, ensuring smooth, reliable seating every time you load a mag. It's the kind of detail that prevents fumbles at the range or in the field.

Debris ingress is a real concern with any firearm carried or used outdoors. This grip frame insert acts as a barrier, keeping dirt, dust, and moisture from working into the frame cavity where they can accumulate and cause problems. The insert snaps firmly into place using the factory lanyard hole for retention, so installation is straightforward—no gunsmithing required. The result is a cleaner, more finished look to your pistol's grip while addressing a genuine functional weakness in the Glock platform.

The PGGFI is designed for full-size Glock models including the 17, 18, 19, 22, 23, 24, 25, 31, 32, 34, 35, 37, and 38. If you run a Gen 4 full-size Glock, this insert accommodates the factory interchangeable backstraps, so you don't lose any modularity. It's a low-cost upgrade that improves function and appearance without altering your pistol's capacity or performance.
