The HK45 Compact Tactical builds on the tough, military lineage of the Heckler & Koch HK45 series of handguns to devise the ultimate operator's pistol. The HK45 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 and feature polygonal rifling for longer barrel life and better accuracy. An HK proprietary internal mechanical recoil reduction system reduces the recoil forces affecting the weapon and shooter by as much as 30%, improving shooter control during rapid firing and prolonging component service life. An integral Picatinny rail is molded into the polymer frame dust-cover for mounting lights, laser aimers, and other accessories. 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 tactical model has a threaded barrel. This double-action pistol features 3-dot night sights and comes with two 8-round magazines and the original factory case. Its grips, metal, and bore are all in very good condition.
