MK23 Pistol (named MK23 Mod 0 in milspec version) is a semi-auto handgun consisting of a match grade handgun, a laser aiming module (LAM) and supressor. It was designed as an “offensive” handgun based on the USSOCOM Offensive Handgun Weapon System
Project around late 1991 and did competition with its rival OHWS Pistol. After MK23 won the competition, it developed into MK23 Mod 0 and delivered to SOCOM in 1996. Its civilian version, named MARK 23, was offering on the market at the same time.

MK23 had extreme high accuracy due to its big size and it can chambered high-pressure match grade cartridges, but its big size decreasd its ease of use, comfort and draw speed in defensive situations. Also, MARK 23 was offered on the civilian market for limited quantity and already discontinued in 2010.
