PP90M1

The  is a submachine gun that appears in Call of Duty: Modern Warfare 3.

Campaign
The weapon first appears in the level "Hunter Killer", where it can be found with or without a Red Dot Sight. It can also be found with a silencer. It is also found in the mission "Turbulence", carried by Makarov's men. It is also seen wielded by Russian forces in "Mind The Gap" and African Forces in "Back on the Grid" and "Return To Sender".

Multiplayer
The PP90M1 is available from start in the Grenadier default class and unlocked at Level 28. It doesn't have high recoil, but it does have a somewhat obstructive muzzle flash.

The PP90M1 is a very versatile submachine gun, ideal for short to medium range combat. There are a variety of useful attachments for the PP90M1. The Suppressor is a good choice since it eliminates muzzle flash, making it easier to stay on target. This is especially true at medium range, where damage drop off is not as much of an issue because of its very high fire rate and low recoil. Red Dot is another good choice since it is gives a clearer view on target and the muzzle flash is not as obstructive. Extended Magazines or Rapid Fire make good attachments for this weapon, especially when coupled together. The increased magazine size can also compensate for the high rate of fire. This combo allows enemies to be quickly dispatched at close range, without fear of depleting the magazine.

Scavenger or Sleight of Hand are good perks to help increase ammo or decrease reload times for this weapon, as it has a moderately long reload time. Steady Aim is very useful as the high fire rate makes it very easy to dispatch multiple enemies at close range without having to aim down the sights, saving time and potentially preventing the player's death.

Range is a useful Proficiency for the PP90M1 as it removes one of the weapon's main weaknesses and allows the user to be more flexible with the gun on larger maps.
