Pearce Grip PG19G5 Polymer Grip Extension with Black Finish & 1/2" Gripping Surface for Glock Gen4-5 Mid & Full Size Models

The Pearce Grip PG19G5 is a polymer grip extension designed for Glock Gen 4 and Gen 5 mid-size and full-size pistols. If you shoot a Glock regularly—whether at the range, in competition, or for carry—you've probably noticed that extended grip real estate makes a difference in control and comfort. This grip extension replaces your magazine base plate and adds roughly half an inch of gripping surface without changing how many rounds your magazine holds. It's a simple upgrade that addresses a real ergonomic gap on stock Glock baseplates.

Made from high-impact polymer with a black finish, the PG19G5 is tough enough for serious use. The grip extension works on Gen 4 and Gen 5 double-stack magazines with capacity greater than 10 rounds—specifically those with the dual notches for ambi magazine release. For Gen 5 shooters, Pearce includes an optional filler piece that accommodates the semi-circular cut-out found on the lower front of Gen 5 grip frames, so you get a clean, consistent fit across all mid and full-size Gen 5 models.

Installation is straightforward: swap out your existing magazine base plate for the extension. No gunsmithing required. Whether you're building a duty rig, fine-tuning a competition gun, or just want better purchase on a carry pistol, this is the kind of small mod that pays dividends when you're actually shooting. It's affordable, reliable, and does exactly what it promises.
