The Pearce Grip PG1045+ polymer magazine extension is a simple, effective way to add capacity to your Glock Gen4 high-capacity magazines. This extension replaces your factory floor plate and adds two rounds to compatible models, giving you a quick boost in firepower without changing your carry setup or handling characteristics. It's the kind of modest upgrade that makes a real difference in a defensive or competition context where every round counts.
Built from durable polymer in black, the PG1045+ is designed specifically for Glock's high-capacity magazine lineup—models 20, 21, 29, 40, and 41. It's engineered to work with both third and fourth generation Glock platforms. Installation is straightforward: the extension simply replaces your existing magazine floor plate. There's no gunsmithing required and no permanent modifications to your magazines.
A key detail worth noting: this extension is designed for high-capacity magazines only. It will not function on 10-round factory magazines in the M20 and M21 models. However, if you're running Glock M30 9-round magazines, the PG1045+ will reliably extend them to 11 rounds, adding real utility to a smaller platform. Reliability and fit are straightforward—Pearce Grip's polymer construction has proven track record with Glock shooters, and the extension maintains the same reliability you expect from factory Glock magazines.
