The Pearce Grip Extension is a practical solution for shooters who want more ammunition capacity and improved ergonomics from their compact Glock pistols. This extension replaces the magazine base plate and internal floor plate, adding two rounds to the Glock 26 and one round to the Glock 27 and 33 models.
This extension is designed exclusively for Generation 4 and 5 Glock magazines equipped with double notches for ambidextrous magazine release. Some early Generation 4 Glock 33 magazines may require modification. Allow a 250-round break-in period with newer magazine springs to ensure smooth loading of the additional round.
Simply replace your existing magazine base plate and internal floor plate with this extension. No gunsmithing required.
