Tyrant CNC Magazine Extension Features The Tyrant CNC Magazine Extension is built specifically for Glock 43X/48 10 round magazines adding 4 rounds of 9mm capacity through a precision machined aluminum base pad. Finished in gold the extension stands out against a standard black pistol while still being milled from aerospace grade aluminum for strength. A new power spring ships with every extension replacing the factory spring to maintain reliable feeding across the additional rounds rather than simply stretching the original spring s capability. Smooth chamfered edges on the extension prevent snagging on clothing or gear during concealed carry. No tools are necessary for installation making this among the fastest installing magazine extensions on the market for the Glock 43X/48 platform. Beyond the added capacity the extension also gives shooters a larger surface to grip at the base of the magazine improving control and purchase during reloads. This is particularly useful on a micro compact pistol like the 43X or 48 where a shorter magazine can be harder to index quickly. The Tyrant CNC Magazine Extension is available for sale at GrabAGun for Glock 43X/48 owners who want more capacity and better magazine handling without compromising reliability.
