Built to the original Over-the-Horizon Weapon System standards, this Mark 23 retains the design elements that set the platform apart. It is German-made with DE and CIP N proof marks, and imported by HKI Columbus, GA. The matching serial numbers on the barrel hood and dustcover plate add desirable continuity for collectors and enthusiasts.
The 5.87 in cold hammer forged barrel uses polygonal rifling and an O-ring for consistent lockup. It is factory threaded M16x1 RH with a knurled thread protector, ready for compatible muzzle devices. These features reflect the pistol’s focus on durability and precision.
Controls include a short-recoil DA/SA action, an ambidextrous paddle-style magazine release, and an ambidextrous manual safety with a separate decocking lever. A firing pin block adds an additional layer of internal safety. The one-piece machined steel slide wears a corrosion-resistant finish, and the fiber-reinforced polymer frame keeps weight balanced for a full-size pistol.
Adjustable high-profile 3-dot iron sights provide a clear sight picture. The frame integrates HK’s universal mounting grooves accessory rail for compatible lights. HK’s recoil-reduction system is built in, and the pistol ships with two 10-round steel magazines for a 10+1 capacity.
