The HK Mark 23 is a full-size, semi-automatic .45 ACP pistol developed for demanding service use. Its double-action/single-action operating system combines a deliberate first trigger pull with a shorter single-action follow-up, while the ambidextrous manual safety and automatic firing pin block provide layered controls. The 5.87-inch barrel is threaded for suppressor-compatible accessories, and the polymer grip helps manage the pistol's substantial size and recoil. Standard high-profile sights support a clear sight picture, and the pistol is supplied with a 10+1 capacity and two magazines.
