The HK Mark 23 .45 ACP was designed to meet the demanding requirements of the U.S. Special Operations Command, combining the precision of a match-grade pistol with extreme durability and reliability. This pistol demonstrated an exceptional mean rounds between stoppages (MRBS) of up to 15,122 rounds in rigorous testing with both standard and +P ammunition. With a confirmed service life exceeding 30,000 rounds, the Mark 23 delivers proven endurance. Its accuracy testing resulted in an average 1.44-inch grouping at 25 meters, with some five-shot groups passing through the same hole.
