Enhanced versions of the USP, the USP Tactical models are designed for users who need the features found on the HK Mark 23, but in a more compact pistol. Both pistols approach the precision found on the Mark 23 by adding an extended threaded barrel, and adjustable target-type sights. The 9mm Tactical model is built on the USP 9mm/40 caliber frame. This firearm includes three 15-round magazines and adjustable night sights.
