Extended Backup Magazine for Glock 19/23 - +5 Capacity, Blue Finish

If you carry a Glock 19 or 23, you know that factory magazine capacity can feel limiting in a defensive or training scenario. The Backup Tactical Extended Backup Magazine adds 5 rounds to your mag, giving you more rounds downrange without changing your grip or carry footprint significantly. Built from aluminum with a blue anodized finish, this extension is designed to withstand regular use while maintaining a clean, professional look.

Installation is straightforward—Backup Tactical includes a spring and securing pin in the box, so you're ready to go out of the package. The extension works with standard Glock 19/23 magazines, so there's no need to replace your existing mags or invest in a whole new system. Whether you're building a duty setup, running drills at the range, or just want more rounds available in a carry gun, this extension is a practical, no-nonsense upgrade.

The aluminum construction and anodized finish mean this isn't just a capacity bump—it's built to handle the wear that comes with serious use. The blue finish gives it a distinctive appearance on the range while the engineering keeps it reliable where it counts.
