Steyr TMP

The Steyr TMP (Taktische Maschinenpistole/Tactical Machine Pistol) is a 9×19mm Parabellum caliber machine pistol manufactured by Steyr Mannlicher of Austria. The magazines come in 15 or 30 round detachable box types. A suppressor can also be fitted. Though originally intended to be used without a shoulder stock, an optional fixed stock was made available later.
In 2001, Steyr sold the design to Brügger & Thomet, which developed it into the Brügger & Thomet MP9.
