The Steyr TMP (TMP standing for Tactical Machine Pistol) is a submachine, select-fire, 9 x 19 mm Parabellum caliber gun produced and manufactured by the Austrian company, Steyr Mannlicher.
The TMP is renowned for its precise controllability, the weapon allows a shooter to accurately fire the submachine gun in bursts of up to 15 or 30 (the full magazine size), instead of the conventional 3-shot or 2-shot bursts that other submachine guns are limited to firing. Magazines come in 15/30 round detachable box types. A silencer can be also equipped. The Steyr SSP is a variant of the TMP capable of semi-automatic fire only and does not have too many major differences.
One of the main and popular features of the TMP is the angled handgrip towards the front of the gun. It has been frequently reviewed that it is very comfortable to fire and easy to bring to aim and bear.
In the 1990s Steyr sold off the design of the weapon to Brugger & Thomet who developed the TMP into the Brugger & Thomet MP-9. The new weapon includes such features as integrated Picatinny rails.
The Brugger & Thomet MP-9 is currently being imported into the United States as a civilian-legal pistol by DSArms Inc and is commonly called the TP9 Tactical Pistol.
The TMP-46 (or TMP46) is chambered for the 4.6 x 30 mm cartridge and is an unreleased prototype version.
The Steyr Special Purpose Pistol or SPP is a variant of the TMP with a semi-automatic operation. For the SPP the barrel jackets and barrel on the TMP was lengthened and increased partially making for a greater length of protruding barrel and jacket. On the weapon, the forward tactical handle was extracted and the company installed a small spur.
The Brugger and Thomet MP-9 is essentially a Steyr TMP with a folding stock. The stock folds towards the right side of the firearm and has an equipped Picatinny rail. The Brugger and Thomet TP-9 is the semi-auto version.
