|The following is based on Fallout Tactics and some details might contradict canon.|
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 m and it's also easy to clean.
There are several much better handguns, but the Beretta is found almost everywhere, thus being available when you need it.
