Pearce Grip PGG4MF Grip Frame Insert - Fits Glock Gen4 & Gen5 Mid & Full Size Black Polymer

The Pearce Grip PGG4MF Grip Frame Insert is a low-profile black polymer accessory that drops into the open rear frame cavity of a Glock Gen4 or Gen5 Mid and Full Size pistol. Held in place by a simple friction fit, it closes off the gap behind the magazine well and keeps lint, dirt, and other debris from collecting inside the frame.

Designed to work with the factory interchangeable backstraps on Gen4 pistols, the PGG4MF leaves the backstrap system fully functional so the shooter can swap grip sizes without removing the insert. On Gen5 frames, the plug drops into the open frame channel for the same clean, finished look.

The insert is compatible with Glock Gen4 models 17, 18, 19, 22, 23, 24, 31, 32, 34, 35, 37, and 38, plus Gen5 models 44 and 45 and other mid and full size Gen5 pistols. Molded from a durable polymer with a black finish, it adds minimal bulk and integrates cleanly into the grip frame once installed.

Installation is completely tool-free: the insert slides up into the rear frame opening and seats firmly with friction. Removal is just as easy should you want to return the frame to its factory-open configuration. The Pearce Grip PGG4MF is a no-permanent-modification upgrade that tidies up the look of any compatible Glock while keeping the internals cleaner between range sessions.
