Steyr TMP Machine Pistol (MP)

Steyr TMP Machine Pistol (MP)

The renowned Steyr-Mannlicher began the development of Steyr TMP submachine gun in the early 90s. Production of the weapon eventually started in 1992 until it was disbanded in 2001. Lack of sales was cited as the primary reason why the gun ceased production.

Licenses of production were then transferred to a company in Switzerland, after which a variant of the TMP remains in production. The Steyr TMP is a selective fire weapon that comes with the blow-back operating mechanism. It is suitable for ammunition of 9 x 19 mm. The weapon fires its ammunition through a closed bolt. A distinct character of the TMP is that it sits between automatic pistol and full-size submachine gun.

The TMP is said to be very convenient to control especially in its full auto mode. A large part of the TMP is constructed out of polymers. The weapon comes without any stock and it is possible to shoot using this gun with one hand only. Concealed carrying is accommodated by the weapon’s compact build. The submachine gun functions in two modes: full-auto and semi-auto. These modes can be selected by pressing a dual-stage trigger as well as a selector for firing mode. A single shot will be selected by pulling the trigger halfway. Full-auto fire mode will be selected if the trigger is fully pulled. The fire mode selector and the ambidextrous safety can be found close to the trigger guard.

The Steyr TMP is compatible with magazines of detachable box type, which will be housed in the handle of the pistol. The magazines have 15- or 3-round capacity. A muzzle cap protects the barrel’s muzzle end. The cap is designed in a shape such that it can be fitted with a sound suppressor.

Several variants of the Steyr TMP exist. The Steyr TMP SPP is a pistol of the semi-automatic type that comes without the apparent vertical grip. This model is designed for use by civilians only. Another variant of the weapon is the Brugger & Thomet MP9 submachine gun. As mentioned above, the licenses to produce the Steyr TMP were transferred to a company in Switzerland in 2001. The MP9 model is the result of further development of the TMP by said company. The design of the MP9 includes a stock that can fold to the right side of the weapon. There is also an integrated rail of Picatinny type as well as a trigger safety.
