Finish off the open cavity at the bottom of your Glock grip and keep your carry or duty pistol cleaner with the Pearce Grip Grip Frame Insert (PGG4MF). Purpose-built for Glock Gen4 and Gen5 mid and full-size frames, this low-profile black polymer grip plug installs into the bottom rear cavity of the frame and uses the lanyard hole for retention, helping reduce the amount of dirt, dust, and debris that can work its way into the grip/magwell area during hard use. It’s a simple, inexpensive upgrade that adds real-world practicality without changing how your pistol handles—or interfering with Glock’s factory ergonomics. MPN: PGG4MF • UPC: 605849200071.

Keeps debris out of the frame and magazine well area
The open void in the rear of many Glock grips can collect lint, dirt, sand, and range debris—especially with frequent carry, outdoor training, or hard field use. Pearce’s insert is designed to help keep debris out of the pistol frame (and commonly noted by retailers as keeping debris out of the magazine well area), helping support cleaner handling and easier maintenance over time. palmettostatearmory.com+1
