MARK 23
MARK 23
The HK Mark 23 Caliber .45 ACP pistol gives shooters match grade accuracy equal to that of the finest custom made handguns — yet exceeds the most stringent operational requirements ever demanded of a combat handgun. The Mark 23 provides this accuracy without the need for hand-fitted parts common in custom-built match pistols costing thousands of dollars more. One of the most thoroughly tested handguns in history, the MK23/Mark 23 project originated in 1991 when HK began development for the U.S. Special Operations Command, the organization that directs the activities of America’s most elite military units, including the Navy SEALs and the Army Special Forces.

On May 1, 1996, the first HK MK 23 pistols were delivered to the U.S. Special Operations Command for operational deployment, making the MK 23 the first caliber .45 ACP pistol to enter American military service since the venerable Government Model 1911A1. During testing, MK 23 pistols met the most stringent operational and accuracy requirements ever demanded of a combat handgun. Endurance testing demonstrated a service life of over 30,000 rounds of +P ammunition. To meet the reliability requirement, the pistol had to demonstrate a minimum of 2,000 mean rounds between stoppages (MRBS) with both M1911 ball and +P ammunition. All pistols exceeded the 2000 MRBS with an average of 6000 MRBS. In more than 450 accuracy test firings from a precision firing fixture at 25 meters, MK 23 pistols far exceeded the government requirement, averaging 1.44 inches, with 65 groups of less than one inch. There were four groups of .5 inches, with 5 rounds going through the same hole!

Technology
- Cold Hammer Forged Polygonal Bore
During the 1960s, Heckler & Koch perfected the famous polygonal profile barrel technology. Conventional lands-and-grooves rifling allow propellant gasses to escape around the front of the bullet as it is fired from the barrel muzzle. A polygonal bore profile effectively seals propellant gases behind the bullet—increasing bullet velocity. An added benefit of a polygonal barrel is its resistance to wear. A polygonal barrel will normally outlast a conventional “lands-and-grooves” barrel by thousands of rounds. Polygonal barrels were one of the many radical design elements used on the HK P7 series pistol and this same breakthrough technology is present on all current HK handguns.
- Reinforced polyamide (polymer) frame
A radical new material used on the P9S pistol in the late 1960s, advanced polymers were soon used as major components and assemblies on a variety of HK products — including the receivers of MP5s in the 1960s. HK polymer molding technology led to the introduction of another synthetic framed HK handgun, the futuristic-looking VP70. Heckler & Koch pioneered the use of polymers more than fifteen years before competing firms. Today, HK remains a technology leader in the use of innovative and high-strength polyamides.
