The USP45 Tactical package centers on its 5.09-inch extended barrel with left-hand threads, O-ring barrel interface, and cold-hammer-forged, polygonal rifling. A knurled thread protector is installed to safeguard the muzzle when not in use. The barrel has a 1:16 twist.
Sight upgrades include a high-profile front blade and a micrometer-adjustable rear sight for windage and elevation, paired with a 6.73-inch sight radius. The tall sight line provides suppressor clearance. The pistol uses a DA/SA action with a manual safety, a spurred hammer, and HK’s ambidextrous paddle-style magazine release.
Major metal parts wear HK’s Hostile Environment nitrocarburized finish, and the slide has rear cocking serrations. The black, fiber-reinforced polymer frame features stippled grip panels with the molded HK USP logo. A bolt-on, multi-slot accessory rail adapter is installed for mounting accessories.
Built in Germany, this example bears the German nitro proof (eagle over N), the Ulm proof house antler, "Made in Germany" markings, and the HK "KK" two-letter date code, aligning with the 1990s production era. Capacity is 12+1, and this listing includes two 12-round and two 10-round steel magazines.
