The Warne Glock 17/22 magazine extension is a solid upgrade if you're looking to squeeze more capacity out of your existing Glock magazines without replacing them entirely. This one adds five rounds to a standard 9mm Glock 17 magazine or four rounds to a .40 S&W Glock 22 mag. It's a straightforward way to boost your round count for range time, training, or competition.
Machined from 6061-T6 aluminum billet and finished with a Type II hardcoat anodized gray, this extension is built to handle daily use without showing wear quickly. The machining quality is what you'd expect from Warne, with tight tolerances and a clean fit to your factory magazine. The gray finish gives it a professional look that works well with most setups, and it won't attract attention like some of the brighter colored options out there.
Warne designed this extension with real-world usage in mind. The ergonomic shape makes magazine insertion smooth, and you get strategically placed finger grooves that let you strip the magazine from your gun quickly if you need to. That matters in fast-paced scenarios, whether you're doing competition work or just need reliable mag handling during training. It's not flashy, but it does what it's supposed to do without overthinking it.
You're getting a precision machined component here, not a stamped or cast piece. The Torx head screw and washer retention system is secure and reliable. This is the kind of product that doesn't demand attention because it just works shot after shot. The gray anodized finish resists scratches and corrosion, so your mag extension stays looking solid through hundreds of rounds.
The +5/+4 models come with a new spring included, which is designed to handle the increased capacity reliably. If your extension comes with a replacement spring, the installation instructions will walk you through swapping it out on the factory magazine follower. For most setups, this replacement spring is what you'll want to use to ensure consistent feeding and performance with the extra rounds.
Installation takes about 10 minutes and requires only removing the factory base pad and retaining clip from your magazine. You'll slide the Warne extension onto the magazine flange, secure it with the included Torx screw, and tighten it down. No special tools needed beyond what most shooters already have. Warne includes clear instructions with the extension, and the whole process is straightforward enough for anyone comfortable working on their magazines.
This extension is designed specifically for factory Glock OEM magazines for the 17 and 22 models. Fit on aftermarket magazines may vary depending on the manufacturer, so it's best to test it on your specific magazines before committing. Most quality aftermarket mags follow similar dimensions to factory specs, but tolerances can differ.
Yes, this extension is commonly used in competition settings where capacity limits allow it. The ergonomic design with finger grooves actually helps with faster magazine changes, which competitors appreciate. Just verify that the total capacity you end up with meets the rules for your specific shooting discipline or competition division before you rely on it for match day.
