The HK Mark 23 offers match grade accuracy equal to that of the finest custom made handguns — yet it exceeds the most stringent operational requirements ever demanded of a combat handgun. It boasts a cold hammer forged polygonal barrel with reinforced polymer frame for durability, resistance to wear. H&K polygonal barrel will outlast a conventional “lands-and-grooves” barrel. This semi-auto pistol features a 5.87-inch barrel chambered in .45 ACP with a 10 round capacity. The one piece machined steel slide features forward slide serrations for a confident grip and anti-glare longitudinal ribs. It integrates fixed sights for rapid target acquisition and accurate shooting. The Mark 23 offers oversized trigger guard for use with gloves and universal mounting grooves for installing accessories. The Heckler and Koch Mark 23 features a corrosion resistant blued finish and corrosion proof fiber-reinforced polymer frame. The versatility of this pistol is further demonstrated with the inclusion of an ambidextrous slide release and ambidextrous magazine release. The HK Mark 23 is ideal for the user looking for match grade accuracy from the match grade trigger to its patented HK recoil reduction system.
