MAC-10

The Military Armament Corporation Model 10 (more popularly known as the MAC-10) is a machine pistol.

History
The MAC-10 was developed in 1964 by Gordon B. Ingram. It is sometimes also referred to as the M-10 because of the frequent usage by MAC-10 by gun dealers, writers, and collectors. The MAC-10 is chambered exclusively for either the .45 ACP or the 9mm Parabellum, although there are variants chambered for different rounds, such as the MAC-11, which is chambered for the .380 ACP. The machine pistol is best known for its ability to accept a certain type of suppressor, which was designed by Mitchell Werbell III of Sionics and boasted a unique two-stage design that involved the first stage being larger than the second, allowing for effectiveness in silencing the automatic gunfire as well as easier maneuverability for the MAC-10. The MAC-10 came under fire in the U.S. in 1994 after the Federal Assault Weapons Ban was imposed; not only did it violate two important requirements dictated by the ban, but it was directly named in it. The ban has since expired in 2004. The MAC-10 was used in the U.S. during the Vietnam War, particularly by LRRP and Navy SEAL teams.
