Product Summary

The HK45 combines the accuracy, modularity, reliability, and minimum 20,000 round service life of the renowned USP45 Compact with the improved ergonomics of the P2000 series pistols. Smaller in length and height than the standard HK45, the HK45 Compact uses a slim-line grip profile, but otherwise is nearly identical in features to the full-size HK45. The HK45 Compact uses an HK proprietary O-ring barrel for precise barrel-to-slide lockup and optimal accuracy. HK45 barrels are made using the famous HK cold-hammer forging process for superior performance. Using HK's unique internal mechanical recoil reduction system reduces the recoil forces imparted to the weapon and shooter by as much as 30%, improving shooter control during rapid firing and increasing component service life. The HK45 also uses an improved USP-style control lever, a combination safety and decocking lever that's frame-mounted and easily accessible. An integral Picatinny rail molded into the polymer frame dust cover allows for mounting lights, laser aimers, and other accessories. Each HK45 Compact comes standard with an extra backstrap for a custom fit for each shooter's hand.
