The Warne Magazine Extension for Glock adds five rounds of 9mm capacity to a Glock 17 and four rounds of .40 caliber capacity to a Glock 22, giving shooters added firepower without sacrificing reliability. Warne magazine extensions for Glock PMAGs are available in multiple color options and are offered in both increased-capacity models and zero-capacity models designed for 10-round restricted states. Built for durability and performance, these extensions are engineered to handle demanding range sessions and defensive applications alike.

Designed with an ergonomic profile, the extension improves magazine handling during reloads while also providing enhanced grip and control. Integrated finger grooves make it easier to strip the magazine from the handgun if necessary, especially in high-stress or competitive shooting environments. The added length also creates a more comfortable purchase for shooters with larger hands, improving overall handling and control during rapid fire.

The extra capacity and improved ergonomics of the Warne Magazine Extension can be especially beneficial in dynamic shooting situations where fast reloads and precise follow-up shots matter most. Whether used for competition, training, or personal defense, this extension offers a practical upgrade for Glock owners looking to maximize both performance and functionality.
