The Staccato HD C4X Premium Package is an elite, compact semi-automatic pistol chambered in 9x19mm Parabellum. Co-developed alongside a metropolitan tactical surveillance unit, this high-performance handgun departs from traditional 2011 conventions by accepting 15-round Glock-pattern magazines and discarding the grip safety for a higher, more consistent tang grip. Built on a lightweight, billet-machined 7075 aluminum frame, it features a 4-inch, one-piece barrel with an integrated compensator designed to drastically diminish muzzle flip without compromising concealability. The slide is treated with a rugged Diamond-Like Carbon (DLC) finish and is milled with Staccato X-Series lightning-cut serrations distinctive to the Premium Package. Further maximizing duty reliability, the slide houses the robust HD HOST optic system, an external extractor, and an active mechanical firing pin block.
