Warne Magazine Extension for Glock 17/22 – +3/+2 Rounds, Black

The Warne Magazine Extension increases capacity for Glock 17 and Glock 22 magazines, adding 3 rounds to 9mm models and 2 rounds to .40 S&W models. This extension is designed for shooters who want additional firepower without moving to a higher-capacity platform, making it a practical upgrade for competition, home defense, or range use.

Machined from aircraft-grade aluminum with a black anodized finish, this extension installs without permanent modification to the magazine. Installation requires disassembly of the magazine base plate and replacement with the Warne extension—no gunsmithing needed, but proper magazine spring tension and function testing are essential after installation. The extension maintains reliable feeding and does not compromise the magazine's structural integrity.
