The Warne 3113 Magazine Extension for Glock 17/22 is a US-made aluminum extension built for shooters who want more rounds on tap without sacrificing reliability. Machined from 6061-T6 aluminum billet and finished in hardcoat anodized FDE, it adds 5 rounds to 9mm magazines or 4 rounds to .40 S&W mags—a meaningful boost for defensive carry, competition, or range work. The extension handles abuse well: the Type 2 hardcoat anodize resists corrosion and abrasion, and a Torx head screw with washer locks everything in place. Whether you're running a Glock 17 or 22, this extension gives you the capacity boost without the bulk of a wholly different magazine.
What sets the Warne 3113 apart is its ergonomic profile and finger grooves. The shape makes insertion smooth and natural, and the grooves let you strip the magazine from the gun one-handed if you need to—useful when transitions matter. It's a straightforward, proven design: clamp it on, cinch the screw, and it becomes invisible until you need those extra rounds.
Built and tested in the USA, this extension is a trusted choice for Glock users who refuse to compromise on durability or American manufacturing. If your 17 or 22 is a duty, carry, or match gun, the Warne 3113 earns its place in your magazine lineup.

Yes, the extension is designed to fit both the Glock 17 (9mm) and Glock 22 (.40 S&W). However, the capacity gain differs: 5 additional rounds for 9mm magazines, and 4 additional rounds for .40 S&W magazines.
The Warne 3113 comes with the aluminum extension body, a Torx head screw, and a washer for attachment. You'll install it on your existing Glock magazine using the included fastener.
The extension is machined from 6061-T6 aluminum billet and treated with Type 2 hardcoat anodize, making it durable against corrosion and wear.

Yes. The Type 2 hardcoat anodize finish is specifically chosen for abrasion and corrosion resistance, so the FDE color will hold up through heavy use, carry, and field conditions.
