The HD P4 pairs a 4-inch 9mm barrel with a robust 4140 steel frame and an aggressively textured polymer grip module for control. Its single-action, hammer-fired system uses an external hammer, an ambidextrous thumb safety, and a firing pin block. The skeletonized, curved trigger with lightening cuts is designed for a clean break.
The optics-ready slide includes forward-leaning front and rear cocking serrations and a removable top cover plate. A Trijicon green-dot front post provides a clear aiming reference, and the matte black finish on both slide and frame keeps glare low. Sighting configuration may vary depending on the installed optics plate.
The full-length dust cover incorporates a 4-slot Picatinny rail for mounting a light or accessory. Dimensions are approximately 7.6 in overall length, 5.5 in height, and 1.6 in width, with an unloaded weight reported at approximately 32–35 oz.
Capacity is 18+1, and this example includes six 18-round steel magazines. Uses Staccato 2011 double‑stack steel magazines; not compatible with Glock magazines. Country of origin is USA, and the pistol carries clear model and caliber markings throughout.
