Origin
Brazil
During the 1990s Taurus replaced in production its MT-12A submachine gun (licensed copy of the Beretta PM-12) with another foreign design, this time purchased from Chile. Originally known as the FAMAE SAF, in Brazil it is made in a slightly modified form as the Taurus MT-9 (in 9mm Luger). In this case, the MT index stands for Metralhadora Taurus – Taurus Submachine gun, and the digits denote a caliber. The Taurus MT-9 G2 line of submachine gun first appeared in early 2011, apparently to replace older Taurus MT submachine guns in same calibers. This weapon represents 2nd generation of Taurus submachine gun, hence the apparent G2 addition to the name. Compared to 1st generation weapons, new Taurus MT G2 submachine guns offer more noticeably lower and controllable rate of fire, better ergonomics and probably more economical production, thanks to use of more modern manufacturing techniques. It is yet to be seen if these weapons will be adopted by any major force, though. Taurus also offers a semi-automatic version of the G2 line, known as CT G2, which is intended primarily to civilian and security markets.
