Description

If you carry a Glock 19 or 23, this Warne magazine extension gives you those extra rounds when it counts. It adds 3 rounds of 9mm capacity or 2 rounds of 40 S&W to your factory magazines, which might not sound like much until you need them. The design feels like a natural extension of your mag rather than an afterthought.

Built from Aircraft-Grade Aluminum

Warne machined this extension from 6061-T6 aluminum and finished it with a hardcoat anodized black coating, so it can handle the rough and tumble of range days and field use. The finish holds up to repeated loading cycles and won't scratch off from standard handling. It matches your Glock's aesthetics while delivering serious durability.

Ergonomic Shape and Grip Features

The extension has an ergonomic design that makes magazine insertion smoother than a bare basepad, and the finger grooves actually serve a purpose. Those grooves help you strip the magazine from your gun if you need to, which matters whether you're running drills or competing. Installation is straightforward. You remove the factory base pad and retaining clip from your magazine, slide the extension onto the magazine tube, and secure it with the included Torx head screw and washer. No special tools needed beyond what you probably already have.

Simple Installation and Tested Reliability

The extension comes pre-assembled and ready to go. Just make sure your magazine tube is clean before sliding it on. Once installed, it seats reliably on your magazine and functions with the same consistency as factory equipment. For those who run their Glocks hard, this is the kind of upgrade that works every time without drama.

Frequently Asked Questions

How hard is it to install this Warne magazine extension?

Installation takes just a few minutes. Remove the factory basepad and retaining clip from your magazine, clean the magazine tube, then slide the extension onto the tube flange. Secure it with the included Torx screw and washer and tighten firmly. No special tools or gunsmithing required.

Will this extension work with aftermarket Glock magazines?

This extension is designed for factory Glock 19 and 23 magazines. Before installing on any magazine, make sure the magazine tube has a smooth transition and no excess material that could interfere with the extension. If you're using aftermarket mags, verify compatibility first.

Does the finger groove actually help with mag stripping?

Yes. The groove gives your thumb or finger a positive grip point to pull the magazine from your gun quickly and reliably. It's especially useful if you're running mag changes under stress or in competition where smooth reloads matter.

How does this compare to other Warne extensions for the G19/23?

Warne makes this extension in a +3/+2 capacity and a larger +5/+4 capacity option. The +3/+2 is a conservative increase that keeps the overall profile relatively compact, while the +5/+4 adds significantly more rounds at the cost of extra length and grip real estate.
