Who the pistol was made for. Beretta makes both. The M9 is simply the U.S. military designation of the 92FS pistol. The military pistols are marked as such. Functionally they are the same. Both are available on the commercial market. The M9 comes in a cardboard box instead of a plastic box and costs about $50 more, but as stated above, functionally, they are the exact same gun.
The Beretta 92F (also known as model 92SB-F) was developed in 1983. This model is a further modification of the model 92SB that featured a slightly re-shaped grip, plastic grip panels and a new, more durable finish. The Beretta 92FS was submitted for USA XM9 Army Pistol Trials in 1985. Adopted by US Military as a M9 pistol, 9mm. Manufactured both in Italy and in USA. Also adopted by many other military and law enforcement forces. Features chrome lined barrel, recurved triggerguard for improved two-hands grip, new grip panels and lanyard ring, 'Bruniton' finish, and a trigger bar disconnect safety.
Beretta has been making guns since the 1500s. You DO realize that there is more than ONE Beretta, and more than ONE magazine for them? You will need to be more specific.
Impossible to answer- there is more than one Beretta gun.
