The MAC-10, abbreviation of Military Armament Corporation Model 10, is a recoil operated sub-machine gun (technically, a "machine pistol") developed in the United States from the 1960s to 1980s. The gun was originally designed for use by police forces, and even saw limited service in the Vietnam War, however it was soon proven that such a small gun cannot accurately fire beyond 20 meters at such a high rate of fire. Its manufacture continued until 1986 when post-dated fully automatic firearms were banned for civilian ownership, and no government agencies showed interest. The MAC-10 achieved success through Hollywood rather than real life, because few of the guns ever made it into the hands of criminals, and even then were marginally effective. In GTA Vice City and Liberty City Stories, the MAC-10 has an unbelievably fast rate of fire and can shoot up to 30 rounds in five seconds. In fact, it is faster than the Micro Uzi, but qualifies as the weakest firearm in the game, dealing only 15 points of damage. In GTA Vice City Stories, the silencer has slowed down the MAC-10's rate of fire and thus it's not able to fire as many rounds at a limited amount of time as its predecessor. The silencer on this incarnation of the MAC-10 may be a reference to the 1994 film Pulp Fiction.
In-game
Typically, no one uses the Mac-10 in GTA Vice City, except for the Ammu-Nation owner in Ocean Beach if threatened by the player. In Vice City Stories, the Silenced Mac-10 is used by many players throughout the game. Some of your gang members use Macs to defend themselves.
