Steyr TMP

The Steyr TMP, short for Taktische Maschinenpistole or Tactical Machine Pistol, is an Austrian machine pistol made by Steyr Mannlicher and chambered in 9x19mm Parabellum. It was designed by Friedrich Aigner around 1989 and built from 1992 to 2001, using a short-recoil action with a rotating locking barrel and a high cyclic rate of about 850 to 900 rounds a minute. Magazines hold 15 or 30 rounds and a suppressor can be fitted. It was first meant to be fired without a shoulder stock, though an optional fixed stock was added later. A semi-automatic variant, the Steyr SPP or Special Purpose Pistol, has a longer barrel and jacket and no forward grip. Users named in the article include the Austrian police unit EKO Cobra and the Italian special forces unit Gruppo di Intervento Speciale, and Myanmar has produced it locally as the MA-13 MK-II. In 2001 Steyr sold the design to Brugger and Thomet, which developed it into the MP9.
