Heckler and Koch (HK USA) | USP45 Expert | 45 ACP | Blue

The USP45 runs the same modified Browning‑type cam‑locked action and patented recoil reduction system as the rest of HK's USP line, scaled up to .45 ACP -⁠- genuinely proven since the early 1990s as a duty and law‑enforcement sidearm. A polygonal‑rifled barrel improves bullet‑to‑bore seal for real accuracy and easier cleaning versus traditional lands‑and‑grooves rifling, and the DA/SA trigger with a safety‑decocker lever gives deliberate control over the pistol's carry condition. Universal accessory‑mounting grooves and an oversized trigger guard round out a pistol built for genuine duty use, not just a range gun. This is the USP45 Expert configuration, HK's target‑oriented variant with a longer barrel and refined sights built for genuinely tighter groups than the standard duty USP45.
