Frequently Asked Questions
Will this extension work with both the Glock 19 and Glock 23?
Yes. The Warne Mag Extension is specifically designed to fit the standard double-stack magazines used in both the Glock 19 (9mm) and Glock 23 (.40 S&W). Always verify your magazine's baseplate compatibility before installation to ensure a proper fit.
Is a 10-round compliant version available for California residents?
Yes. Warne offers a zero-capacity model of this extension that does not increase your magazine's round count, keeping it within California's 10-round limit while still providing the ergonomic grip and finger groove benefits of the full extension. Be sure to select the correct model at checkout.
How difficult is it to install the Warne Mag Extension?
Installation is straightforward and requires only a Torx screwdriver. The extension replaces your magazine's existing baseplate and is secured with the included Torx head screw and washer. No gunsmithing experience is required, and most users can complete installation in just a few minutes.
