The Pearce Grip PGFI21G4 is a grip frame insert designed specifically for Glock 20, 21, and 41 Gen4 pistols. This black polymer plug fills the frame cavity at the bottom rear of your Glock, eliminating the empty opening that comes stock on these models. It's a simple upgrade that addresses a practical concern: keeping dirt, debris, and moisture out of your pistol's internal cavity while giving your gun a cleaner, more finished appearance.

Installation is straightforward—the insert uses the lanyard hole for retention, snapping firmly into place without any gunsmithing required. The front lip of the insert forms a tight, flush fit with the magazine well, helping ensure smooth and reliable magazine seating every time you reload. For Gen4 Glock owners, this insert is designed to work alongside the factory interchangeable backstraps, so upgrading your grip doesn't compromise that versatility.

Whether you're a competitive shooter, hunter, or carry enthusiast, the Pearce Grip frame insert is a no-nonsense way to seal up your Gen4 Glock's frame without adding weight, changing ergonomics, or increasing magazine capacity. It's the kind of small detail that separates a well-maintained pistol from one that's exposed to the elements.
