Tyrant CNC Magazine Extension for Glock 19/23 – +5/4 Rounds, Gray

The Tyrant CNC Magazine Extension increases capacity on factory Glock 19 and Glock 23 magazines by +5 rounds (9mm) or +4 rounds (.40 S&W). This extension allows shooters to carry more ammunition without switching to a full-size magazine, maintaining the balance and concealability of a compact frame while gaining extra rounds for competition, duty, or personal defense.

Machined from 6061-T6 aluminum with a Type III hard anodized gray finish, this extension is both lightweight and durable. Installation is straightforward and requires disassembly of the magazine base plate—no permanent modification to the magazine body. A new magazine spring or spring kit may be required for reliable function with the increased capacity (not included). Some fitting or adjustment may be necessary depending on magazine generation and condition.
