Who This Is For
This extension is ideal for USPSA, IPSC, and 3-Gun competitors who need every round they can get in a stage, as well as law enforcement officers and civilians who carry or stage a Glock 17 or 22 for self-defense and want a higher-capacity backup magazine. The rugged aluminum construction and secure Torx fastener make it equally at home on a range gun or a duty pistol.

Frequently Asked Questions
Which Glock magazines does this extension fit?
This Warne extension is designed specifically for factory Glock 17 (9mm) and Glock 22 (.40 S&W) double-stack magazines. It is not designed for use with Glock 19, 26, or single-stack variants. Always verify your magazine model before installing any extension.
Is this extension legal to use in California and other capacity-restricted states?
California currently restricts magazines to a maximum of 10 rounds for most civilian use. Since this extension increases magazine capacity beyond 10 rounds, it may not be compliant for standard civilian use in California or other states with similar restrictions. Warne does offer zero-capacity (cosmetic) extensions for 10-round-limit compliance — consult your local laws or a qualified attorney before purchasing this model.
Does installing this extension affect magazine reliability or feed reliability?
When properly installed using the included Torx screw and washer, the Warne extension is designed to maintain reliable feeding and function. The machined aluminum construction holds tight tolerances that keep the follower and spring aligned correctly. As with any magazine modification, we recommend testing with your specific firearm and ammunition before relying on it for duty or defensive use.
