The HK Mark 23 .45 ACP FDE pistol is a handgun with a 5.87-inch threaded barrel and an ambidextrous safety lever, finished with a Flat Dark Earth frame (Heckler & Koch part no. 81000869). Heckler & Koch developed the Mark 23 for U.S. Special Operations Command, and the design pairs a match grade trigger with a one piece machined steel slide. The patented HK recoil reduction system and polygonal bore profile support its reputation for accuracy. It is a serious full-size pistol for range work, collecting and duty-style shooting.
