The HK45 Compact Tactical builds on the rugged, military heritage of the Heckler & Koch HK45 series of handguns to create the ultimate operator's pistol. The HK45 pistol series (compact and full-size models) was chosen as the first firearms produced at HK's American manufacturing facilities, making it fitting that a variant would be adopted as the official pistol of a major U.S. special operations unit. The HK45 Compact Tactical (CT) is the closest civilians can get to that military pistol. The HK45 CT comes standard with a threaded barrel, a 10-round magazine with an extended floorplate, and replaceable backstraps to customize the feel and grip size of the pistol for individual hand sizes and shooting preferences.
