The Staccato HD P4X Premium Package takes Staccato's HD platform to its highest factory configuration, combining a full-size steel frame with a 4-inch integral compensated barrel, optics-ready slide, Trijicon night sights, X-cut slide treatment, and an 18+1 capacity. Chambered in 9mm, the HD P4X is designed around a heavier steel frame and integrated compensator to help reduce muzzle movement and provide a smooth, controlled shooting experience.

This Premium Package adds the distinctive X-cut slide, Trijicon tritium front sight, HD Tactical Magwell, and four 18-round steel magazines. The HD platform also features fully ambidextrous controls, a reversible magazine release, active firing-pin block, accessory rail, and Staccato's HOST optics-mounting system. Unlike traditional 2011 magazine systems, the HD P4X is designed around Glock-pattern magazines.
