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

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 gives shooters substantially more ammunition on board without requiring a bulkier full-size frame, making it popular for duty use, competition, and personal defense applications where capacity matters.

Machined from billet aluminum with a durable Flat Dark Earth anodized finish, this extension replaces the factory baseplate and installs with the original magazine spring and follower. Installation is straightforward for users familiar with Glock magazine disassembly—no gunsmithing required. The extension maintains reliable feeding and adds minimal length to the grip, preserving concealability while delivering meaningful capacity gains.
