H&K MARK 23 45 AUTO THREADED
The Heckler & Koch MK 23, MK 23 MOD 0, Mark 23, or USSOMARK 23 is a semi-automatic large-frame pistol chambered in .45 ACP, designed specifically to be an offensive pistol. The USSOversion of the MK23 came paired with a laser aiming module (LAM) and suppressor. The USSOMK23 was adopted by the United States Special Operations Command (USSOCOM) for special operations units, beating out the nearest competitor, Colt's OHWS. Development of the pistol began in 1991 as special operations representatives identified the need for an "Offensive Handgun Weapons System—Special Operations Peculiar", and delivery of the pistols began in May 1996 to the special operation units.
While the USSOMK23 designation usually applies to the complete system, it is also commonly used in reference to the pistol component alone. The LAM and suppressor were developed by Insight Technology and Knight's Armament Company (KAC), respectively. The civilian version of the Mk23 sold by itself is designated the Mark 23.
