Tyrant CNC +6/5 Magazine Extension Features The Tyrant CNC +6/5 Magazine Extension is CNC machined from aerospace grade aluminum giving the base pad the added mass needed to help a magazine drop free quickly and consistently during a reload. The extension adds six rounds of capacity to 9mm Glock magazines or five rounds to .40 caliber magazines a notable gain for shooters in competition or duty roles who value having more rounds on tap. Smooth chamfered edges are machined into the extension to keep it comfortable against the hand while still providing enough surface to aid magazine insertion. A new power spring is included with every extension to ensure the added capacity feeds reliably rather than straining the factory spring. Designed to fit the Glock 17 19X 22 34 35 and 45 the extension covers a wide range of popular full size Glock models without requiring different parts for each. Installation requires no tools making it one of the simplest upgrades a Glock owner can perform at home. The extension does not work with Pmags or existing 10 round magazines so fitment should be checked against factory Glock magazines before purchase. Finished in a durable Gold anodized coating the Tyrant CNC +6/5 Magazine Extension gives Glock shooters a quick tool free way to add meaningful capacity to their existing magazines.
