TMP

The Steyr TMP (Tactical Machine Pistol) is a machine pistol in Call of Duty: Modern Warfare 2. It is an Uzi-style submachine gun with a built-in foregrip and side folding stock, and has a top surface-integrated rail for attaching sights.

In-game
The TMP is a pickup in Estate Takedown on a wall with lots of other weapons, and comes with a red dot sight attachment. It appears to have the same dual color pattern as the Glock 18.

Trivia

 * While technically the same weapon, the TMP and MP9 have several noticeable differences. The in game model is closer to the MP9 as it has Picatinny rails, and a folding stock.
 * The Modern Warfare 2 variant's suppressor is slightly shorter than it should be. The real life TMP's suppressor is actually bigger than the gun itself.
