9mm Parabellum
beretta makes the m9.. you may be talking about the same thing.
The M9 is made by Fabbrica d'Armi Pietro Beretta - the Beretta corporation. It's an Italian company.
The M9 is a standard 9mm round. the M9 is actually a .355 caliber
Carlo Beretta, Giuseppe Mazzetti and Vittorio Valle from Beretta's design team all had a hand in creating the Beretta 92, which is what the M9 is.
The Beretta M9 was adopted by the US military in the year 1985.
The Beretta M9 pistol is chambered for the 9x19mm Parabellum cartridge, commonly referred to as 9mm. This caliber is widely used by military and law enforcement agencies around the world due to its effective balance of stopping power and manageable recoil. The M9 has been the standard sidearm for the U.S. military since the 1980s.
The FS is the most advanced model of the Beretta 92. I wouldn't recommend the early M9 pistols (which were basically Beretta 92F pistols) over the 92FS, but the later production M9 pistols are 92FS pistols. The main difference being the the actual M9 pistol production is supervised directly by the DoD.
Yes
The Beretta 92 first entered production in 1975. The M9 variant of the Beretta 92F was adopted in 1985.
That is the correct spelling of the handgun model Beretta M9 (standard issue 9mm pistol of the US armed forces).
M9 Beretta
Beretta is a make of gun. They make rifles, shotgun, handguns and machine guns. Without knowing WHICH Beretta, your question cannot be answered. If you mean the military M9 pistol, no. THAT is a caliber 9mm Parabellum, which is a totally different cartridge from a .38 Special.
