The Tyrant Hellcat Mag Ext +3 Black is a precision aluminum magazine extension designed to add 3 rounds of 9mm capacity to Springfield Hellcat and Hellcat Pro magazines. If you carry a Hellcat as a defensive pistol or use it for sport shooting, this extension addresses one of the platform's main constraints: limited onboard ammunition. Made from 7000 series aluminum and finished with hardcoat anodize, it's built tough enough for daily carry and training without adding complexity or requiring gunsmithing.
Installation is refreshingly straightforward. The extension uses Tyrant CNC's NoBak springer plunger technology, which means it stays locked to the magazine even under harsh treatment—dropped, thrown, or run hard—yet comes off and goes back on without special tools or firearms modifications. You reuse your existing OEM magazine spring, so there's no fumbling with proprietary parts or worrying about compatibility. The sleek profile keeps your gun's aesthetics intact, blending naturally with the Hellcat's compact profile.
This is the right choice if you're looking to extend your magazine capacity without complications. Competition shooters, hunters, and defensive-minded carriers who want more rounds on tap without a larger gun will appreciate the straightforward engineering and no-fuss installation.
