Call Of Duty 4 : Modern Warfare
In Single Player, the M9 is the standard pistol. It is the starting pistol in most of the USMC missions, most enemies use the M9 as their side arm, the exception being the Desert Eagle wielding soldier in Crew Expendable. It is very common in the majority of levels. The levels in which it cannot be obtained in are FNG, The Coup or Death From Above. It is statistically the best pistol in single player, because of its virtually nonexistent recoil, high capacity, and decent power, but it really does not matter due to the abundance of enemy weapons available to pick up. It is actually the only pistol unable to achieve a one shot kill.
It is unusual that Russian Ultranationalists are using the M9, because neither the M9 nor the M92F/FS have ever appeared to be in use by the Russian military. Strangely, if you kill an enemy who is using the M9 it will often have up to a few hundred rounds of spare ammo, unlike most weapons in Call of Duty 4: Modern Warfare.
The M9 has the highest capacity of all the pistols, and has the lowest recoil. However, it has the shortest range, which effectively makes it the weakest. Despite this, at close range, the M9 is just as powerful as the USP .45 and M1911. This, coupled with its larger capacity, better hip fire accuracy while moving (compared to the USP .45), and lower recoil makes it the best pistol for point-blank encounters. In addition, this pistol has one large bonus none of the other pistols possess; it can share ammo with the MP5and Mini-Uzi. This means that whenever one of those two weapons is chosen, using the M9 will grant the player with an extra ammo magazine. With Bandolier, this effect is even greater; giving the player 270 rounds (with the MP5) or 282 (with the Mini-Uzi).
This is the standard pistol players will use when they go into Last Stand. This means if the player does not have a different pistol in reserve, they will go down with an M9 with full ammo.
Call Of Duty : Modern Warfare 2
The M9 returns in Call of Duty: Modern Warfare 2 as a standard sidearm for the Rangers. It now has higher damage, penetration, and fire rate, but is now unlocked at Level 46. Whether or not you have unlocked or equipped it, in multiplayer, it is the pistol you use for Last Stand when no other pistol is equipped.
Even while using ADS, the M9 recoils slightly side-to-side and drastically upwards. Because of this, it is nearly impossible to fire accurately at range, unless it is fired slowly, letting the recoil settle. However, at close range it can be fired as quickly as the user can push the fire button as long as the user counters the upward recoil somewhat. The weapon is most powerful when fired Akimbo at close range, alternating left and right fire buttons. When fired in this manner the user need not worry about recoil.
An M9 equipped with a Silencer makes firing quickly via ADS a little bit tricky, as with each shot the long silencer kicks up and obscures view of your target.
The M9 no longer retains its advantage over the USP .45 with higher hip fire accuracy, as both are the same, nor is it relatively accurate to the other handguns. The USP has a slightly longer 2 hit kill range, with the disadvantage of a 3 round smaller magazine. However, all things considered the M9 is slightly superior due to its larger magazine.
The M9's appearance seems to have been slightly touched-up from Call of Duty 4, as it seems to be slightly shiny and a deeper black.
- The M9 used in Call of Duty 4: Modern Warfare is actually a Beretta 92SB, not an M9.
- The burst-fire version, the M93 Raffica, appears in Call of Duty: Modern Warfare 2.
- The M9's recoil while using the Tactical Knife attachment is different as it kicks the gun upward like if you were to be using the USP .45.
- The M9 has greater muzzle rise in Multiplayer than in the campaign and the Museum.
- Compared to the other semi-automatic handguns, the M9 has the highest magazine capacity.
- When running with Akimbo M9's the camera twitches slightly side to side. The same quirk applies with the G18.
- The M9 portrayed in both Modern Warfare games has the 3-dot sight set up. This is inaccurate, since the real military M9 uses a half-aperture sight.
- The in-game M9 always fires from decocked hammer. In reality it would fire only once this way, and after the first shot the hammer would be cocked by the slide movement.
- The M9 Expert challenge isn't unlocked until level 62, the same time you get the Desert Eagle, which is 16 levels later, however, this is most likely a programming error made by IW.
