This extension is ideal for competitive shooters looking to maximize round count during USPSA or IDPA stages, as well as defensive shooters who want every available round in their Glock 19 or 23 without switching to a larger-frame pistol.

Frequently Asked Questions
Which Glock magazines is this extension compatible with?
This Warne extension is designed specifically for standard Glock 19 (9mm) and Glock 23 (.40 S&W) double-stack magazines. It is not intended for use with Glock 17, 22, or subcompact magazines. Always verify your magazine model before installing.
Is this extension legal to use in California?
California law restricts removable magazines to a maximum of 10 rounds. Because this extension increases capacity beyond 10 rounds when combined with a standard Glock 19/23 magazine, it may not be compliant for use in California. Warne does offer zero-capacity (flush) extensions designed specifically for 10-round-limit states — please consult those options or seek legal advice before purchasing this model for use in California.
Does installing this extension affect the reliability of my Glock's magazine?
When properly installed using the included Torx head screw and washer, the Warne extension is engineered to maintain reliable feeding and function. The ergonomic design and precision machining ensure the extension seats securely without interfering with the magazine spring or follower. As with any aftermarket component, function-testing with your specific firearm before carrying is always recommended.
