HK HK45 Compact Tactical V1

The HK HK45 Compact Tactical V1 is a compact, semi-automatic pistol chambered in .45 ACP. It is based on the HK45 platform originally developed during the U.S. military’s Joint Combat Pistol program and is manufactured in the United States at Heckler & Koch’s facility in Columbus, Georgia using American and German components.

The Compact Tactical variant includes a threaded barrel, adjustable high-profile sights suitable for use with or without suppressors where permitted, and a polymer frame with an integrated MIL-STD-1913 Picatinny rail for mounting accessories. The pistol ships with a 10-round magazine with extended floorplate and supports the use of other compatible HK45 magazines, including 8-round variants. An internal mechanical recoil reduction system is incorporated to manage slide movement and recoil forces during firing. The barrel features an O-ring at the muzzle to support consistent slide-to-barrel alignment. The grip design includes replaceable backstraps to accommodate different hand sizes and user preferences.
