The M9 is a sidearm in Tom Clancy's The Division.
Real World Version Edit
The Beretta M9 is the military variant of the Beretta 92 . It is the primary sidearm of the U.S. military, having replaced the M1911 sidearm in 1986, and was put into service in 1990. Some other models have been adopted to a lesser extent, namely the M11 pistol, and other models remain in use in certain niches.
The M9 is a short recoil, semi-automatic, single-action / double-action pistol which uses a 15-round staggered box magazine with a reversible magazine release button that can be positioned for either right- or left-handed shooters.
