For anyone running a Glock 19 or 23, squeezing out a few extra rounds without changing guns is a smart move. This Warne extension adds genuine capacity to your magazine while giving you a better purchase on the mag itself. Whether you're hitting the range or training for sport shooting, those extra rounds matter.
Built from the ground up for Glock compatibility, this extension is machined from 6061-T6 aluminum and finished with hardcoat anodizing to resist wear and corrosion. The black finish stays understated on your carry or duty setup, blending in without drawing attention. Installation is straightforward, requiring nothing more than removing your factory basepad and swapping in the Warne extension.
The whole point of a mag extension is to make reloads faster and more reliable. Warne designed this one with strategically placed finger grooves that give you a solid grip point to strip the magazine from your belt or chest rig. The extended length also helps the magazine drop free more easily during transitions, a detail that matters when you're training hard or competing. If you need to quickly remove the extension in the field, those grooves let you do that without fumbling.
This extension delivers exactly what Warne promises: five rounds for 9mm mags, four rounds for .40 S&W. That means your standard Glock 19 mag goes from 15 rounds to 20 rounds total. For competitive shooters, that's fewer magazine changes on stage. For everyday carry, it's more rounds on board without sacrificing the size of your gun.
The extension has earned its place in the shooting community by showing up and working reliably through range sessions, competitions, and training courses. It's a simple upgrade that doesn't require new springs or special tuning, though some competitors opt for heavier springs to fully load and run the extended magazine.
The factory Glock magazine spring typically works fine with the extension. Some shooters, especially those running at full capacity in competition, prefer a heavier power spring for maximum reliability under heavy use. For standard range and carry use, the original spring is sufficient.
This extension is designed for Glock OEM factory magazines. Fit on third-party magazines may vary depending on tolerances and design. We recommend testing on your specific magazines before relying on it for critical use.
Installation is straightforward: remove your factory basepad and retaining clip, inspect the magazine tube for debris, then slide the extension onto the magazine flange and secure it with the included screw. No special tools needed. Warne's official instructions recommend ensuring a smooth transition between the tube and extension for reliable function.
Yes. The finger grooves are specifically designed to help you quickly detach the extension if necessary. Simply unscrew it from the magazine, and you're back to the factory configuration.
