The Heckler & Koch Mk.23 is a .45 caliber handgun that has been utilized especially by the United States Special Operations Command Force, also known as SOCOM, in the 1990s. Military versions of the gun have "Mk.23 SOCOM" etched in the barrel, while the civilian model is labelled "Mark 23", although the two guns are nearly identical. The Mk.23 is semi-automatic, and is capable of equipping multiple custom parts, including flashlight, laser sight and silencer. A later version of the Mk.23, called the USP, gained popularity after its release in 1993.
The SOCOM in Metal Gear Solid
The SOCOM is, as any fan of the Metal Gear Solid series will tell you, Solid Snake's favored handgun of choice. It's the weapon he used in Shadow Moses during the first Metal Gear Solid game. It can be found on the helipad in a delivery truck behind some crates in the beginning of the game. The gun can be coupled with a suppressor found later in the story in the Tank Hangar on first floor.
