Pearce Grip PGFI42 Black Polymer Frame Insert for Glock 42/43

The Pearce Grip PGFI42 is a black polymer frame insert designed specifically for Glock 42 and Glock 43 pistols. This compact handgun accessory fills the bottom rear cavity of your frame, addressing one of the most common complaints among subcompact Glock owners: dust and debris accumulation in an otherwise exposed gap. If you shoot, carry, or train with a 42 or 43, a frame insert is a practical addition that keeps your pistol cleaner and looking more finished without altering performance or capacity.

Installation is straightforward—the insert uses the factory lanyard hole for retention and snaps firmly into place. The front lip creates a smooth, flush fit with the magazine well, ensuring reliable feeding and a professional appearance. Unlike some aftermarket parts, this one does exactly what it claims: seals the gap, blocks debris, and stays put. No gunsmithing required, and it doesn't add weight or bulk.

Pearce Grip has built a solid reputation for simple, effective frame inserts across the Glock lineup. The PGFI42 is their answer for shooters who want to protect their investment and maintain cleanliness without fuss. Whether you're running your 42 or 43 at the range, in the field, or as an EDC gun, this insert is a low-cost way to eliminate one small but persistent annoyance.
