MP9

The  is a fully automatic machine pistol featured in Call of Duty: Modern Warfare 3.

Call of Duty: Modern Warfare 3
The gun is very similar to the TMP in Modern Warfare 2, with a similar rate of fire, recoil and almost identical reload, but slower, as the player taps the magazine in place after inserting it, most likely implemented to balance the larger magazine capacity. The MP9 has a darker finish and has different iron sights as well; the rear sight is now open as opposed to the TMP's aperture sight in Modern Warfare 2.

It is the second machine pistol unlocked in the game. With its high rate of fire, large magazine, moderately fast reload, and low, but unpredictable recoil, it is a very versatile weapon. However, it has a few downsides; first, it has the slowest switch time of all the Machine Pistols, with a draw time of .8 seconds. This means the MP9 cannot be easily be pulled out in a heated firefight, such as when one's primary weapon needs a reload. Secondly, it has very low minimum damage and range, taking 6 shots to kill at longer distances. This is not a major problem, however, as its recoil is enough to discourage long range shooting. One of the main advantages of the MP9 is its headshot multiplier, dealing 2x times the damage. The highest multiplayer of any gun, only matched by the Skorpion.
