Pearce Grip PG19 Polymer Grip Extension - Black Finish for Mid & Full Size Glock Gen3 Models
Pearce Grip
The Pearce Grip PGGP polymer magazine extension is a straightforward way to boost ammunition capacity on your Glock mid and full-size magazines without buying new mags. This simple, affordable accessory replaces your factory floor plate and internal locking plate to add 2 rounds to 9mm, .40 S&W, and .357 SIG magazines, or 1 round to .45 GAP—keeping your carry, duty, or range gun topped off without the bulk of oversize magazines. It's made from high-impact polymer engineered to handle the rigors of daily carry and shooting, whether you're working draws at the range or training for defensive scenarios.
Built tough for real-world use, the PGGP extension is rated to withstand drop tests across a temperature range from -20°F to 350°F, so it'll hold up in climates from deep winter to scorching desert heat. The black finish matches standard Glock hardware and keeps a low profile. Installation is tool-free and takes minutes—no gunsmithing required. If you've already invested in Glock mags and want a no-nonsense capacity bump without buying entirely new magazines, this is a solid choice for shooters who value simplicity and reliability.
Pearce Grip has been supplying shooters with magazine accessories for decades, and the PGGP represents their core mission: proven-in-the-field solutions at a reasonable cost. Whether you're a competition shooter wanting a few extra rounds, a concealed-carry holder maximizing your on-duty magazine stack, or someone stocking spares for the range, this extension delivers honest value. It's the kind of upgrade that pays for itself the first time you load up.
