TMP

The Brügger & Thomet MP9 is a new machine pistol in Call of Duty: Modern Warfare 2. The MP9 is derived from the Steyr TMP (Tactical machine pistol), and was modified when the design was bought by Brügger & Thomet, a Swiss manufacturer. 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
