Tyrant CNC Magazine Extension for Glock 19/23 – +5/4 Capacity

The Tyrant CNC Magazine Extension adds 5 rounds to 9mm Glock 19 magazines or 4 rounds to .40 S&W Glock 23 magazines, increasing capacity without requiring extended magazines. This extension is built for shooters who want higher round counts for competition, range training, or personal defense without changing their existing magazine inventory.

Machined from 6061-T6 aluminum with a black anodized finish, this extension installs over your factory magazine baseplate using the included hardware and requires a magazine spring upgrade (sold separately) for reliable feeding. Installation is straightforward but requires disassembly of the magazine and proper spring tension adjustment. The extended baseplate maintains a clean profile and adds minimal length to the grip.
