Tyrant CNC Magazine Extension for Glock 17/22 – +6/5 Capacity, Black

This Tyrant CNC magazine extension increases capacity by 6 rounds for Glock 17 (9mm) magazines or 5 rounds for Glock 22 (.40 S&W) magazines. Designed for shooters who need additional rounds without carrying a second magazine, this extension maintains reliable feeding while adding measurable capacity for competition, duty, or home defense use.

Machined from aluminum with a Type III hard-coat anodized finish in black, the extension installs without permanent modification to factory Glock magazines. Installation requires disassembly of the magazine baseplate and replacement of the factory follower spring with the included extended spring. Basic mechanical aptitude and attention to detail are required—professional installation is recommended if you're unfamiliar with magazine disassembly.
