Backup Tactical Magazine Extension for Glock 19/23 +5 – Red

The Backup Tactical Magazine Extension adds 5 rounds to factory Glock 19 and Glock 23 magazines, increasing capacity from 15 to 20 rounds (9mm) or 13 to 18 rounds (.40 S&W). This extension is designed for shooters who want maximum capacity for competition, range work, or backup duty use without switching to higher-capacity magazines.

Machined from billet aluminum with a red anodized finish, this extension replaces the factory magazine baseplate and installs with basic hand tools. The extension maintains a low-profile grip surface and includes a reinforced spring to ensure reliable feeding with the increased capacity. Drop-in installation requires no permanent modification to the magazine body.
