The HK Mark 23 is a full-size .45 ACP semi-automatic pistol designed for exceptional accuracy and durability. Its 5.87-inch threaded O-ring barrel uses a polygonal bore profile, while the match-grade trigger and one-piece machined steel slide support precise shooting. The corrosion-resistant Blue/Black finish is paired with a fiber-reinforced polymer frame, an oversized trigger guard, universal accessory mounting grooves, and an ambidextrous magazine release. A frame-mounted decocking lever, separate ambidextrous manual safety, loaded-chamber indicator, and Lock-Out Safety device provide additional control. The pistol includes two 12-round magazines.
