Mostly the markings and serial numbers. The early M9s also had a steel guide rod and most 92FS are plastic. I've heard newer M9's also have plastic rods though. The M9 is made in the US. The 92FS is made here and in Italy. They both come off the same assembly line in Accokeek, MD.
The M9 is marked as follows:
Left slide: "U.S. 9mm M9 - Beretta U.S.A. - 65490" followed by the Beretta "PB" logo. 65490 is Beretta's contractor code.
Left frame: serial number - some examples start with "M9-"
Right slide: "ASSY 9346487-65490 PM" where PM is the proof mark
Right frame: "U.S. 9mm M9 - Beretta U.S.A. - 65490"
Hammer: marked on the left side with an assembly number and the 65490 contractor code.
There is now a M9A1 version with a Picatinny accessory rail, aggressive checkering, beveled magwell, and a reversable mag release. It is similar to the 92FS VERTEC.
The 92FS is marked as follows:
Left slide: imports: "PIETRO BERETTA GARDONE V.T. - MADE IN ITALY" followed by the Beretta "PB" logo.
Left slide: current production: "BERETTA USA CORP ACKK, MD - MADE IN USA" followed by the Beretta "PB" logo.
Left frame: serial number
Right slide: top line imports & US: "Mod. 92FS-Cal 9 Parabellum-PATENTED" , bottom line (on some imports): "BERETTA USA. CORP. ACKK, MD"
Right frame: top line: "READ MANUAL BEFORE USE", bottom US made, "FREE FROM BERETTA USA ACKK, MD", bottom line, imports: "WARNING: RETRACT TO SEE IF LOADED, FIRES WITHOUT MAGAZINE"
Hammer: unmarked.
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
an m9 with a silencer and a desert eagle with an extended barrel
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.
Some. I own a Beretta 92FS. It's a variation of the M9 used by the military. Both my gun and all M9s used in the US military are made in the US. However, you can purchase Italian made Beretta guns.
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.
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.
I don't know about other countries, but in the U.S. the standard issue handgun is the Beretta M9 which is basically the same as a 92FS. Some units in the military such as the SEALs, use other guns...Sig 226, I believe.
That is the correct spelling of the handgun model Beretta M9 (standard issue 9mm pistol of the US armed forces).
The Beretta 92 first entered production in 1975. The M9 variant of the Beretta 92F was adopted in 1985.
