Frequently Asked Questions
Will this extension work with all Glock 17 and Glock 22 magazine generations?
The Warne Magazine Extension is designed specifically for standard Glock 17 (9mm) and Glock 22 (.40 S&W) double-stack magazines. It is compatible with factory Glock magazines across multiple generations. If you are using aftermarket magazines, verify the base pad dimensions match standard Glock specs before installing.
Is this magazine extension legal in California and other restricted states?
Warne offers both a +3/+2 capacity model and a zero-capacity model specifically designed to keep magazines at or within the 10-round limit required in California and other restricted states. If you are in California or another state with magazine capacity restrictions, be sure to select the zero-capacity (compliance) version, which provides the same ergonomic and grip benefits without adding rounds beyond the legal limit.
How difficult is it to install the Warne Mag Extension, and do I need special tools?
Installation is straightforward and designed for the end user. You will need a Torx driver to seat the included Torx head screw and washer that secure the extension to your magazine base. No gunsmithing experience is required, and no permanent modification to your magazine is necessary. The extension can be removed and reinstalled as needed.
