The 9mm M9FS Beretta was created in 1975 by the Fabbrica d'Armi Pietro Beretta, military-adopted in 1985, and officially entered service in 1990. It's a short recoil, semi-automatic, single-action/double-action pistol using a staggered box magazine of 15 cartridges caliber 9mm. It provides good accuracy up to 50 meters and it's also easy to clean. The Beretta is readily found in many places in the wasteland.
