Mac 10

The Mac-10 is a sub-machine gun available in Grand Theft Auto: Vice City, Grand Theft Auto: Liberty City Stories and a silenced version in Grand Theft Auto: Vice City Stories. It is known as the Ingram Mac 10 in the original PS2 version of Vice City, Mac in all other versions of Vice City.

Description
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 then 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 unbelievable fast rate of fire and can shoot up to 50 rounds in five seconds. 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 it's predecessor.
