Pearce Plus For Glock Mid/full Size

The Pearce Plus For Glock Mid/Full Size is a high-impact polymer magazine extension engineered to increase capacity in standard-capacity Glock magazines for mid and full-frame platforms. This accessory replaces the original floor plate and internal locking plate, adding measurable round capacity depending on caliber—three rounds for 9mm, two rounds for .40 S&W and .357 SIG, and one round for .45 GAP. The extension maintains the proven reliability of factory Glock components while delivering the tactical advantage of increased ammunition storage without changing your existing magazine ecosystem.

The reinforced polymer construction provides durability and corrosion resistance across extended duty cycles. The added gripping surface along the extension increases control during reloads and manipulations, particularly valuable during dynamic shooting sequences or range transitions where positive magazine purchase matters. At just 0.06 lbs with compact dimensions of 2.4 x 1.3 x 4 inches, the extension adds negligible weight and profile while preserving holster compatibility with most standard Glock duty and concealed-carry rigs. Installation requires no gunsmithing—the extension simply replaces the factory floor plate in minutes.

This upgrade serves law enforcement officers, armed security professionals, and civilian defensive shooters who run mid or full-size Glock platforms and want to maximize onboard ammunition availability without purchasing entirely new magazines. The modest capacity increase per magazine translates to meaningful reserve firepower in multi-threat scenarios while maintaining the ergonomic profile users already trust. Pearce Grip extensions have long been the standard aftermarket choice for Glock magazine enhancement, offering a proven, field-tested alternative to factory-only configurations.
