TheBrügger & Thomet MP9 (German:Maschinenpistole 9mm,lit. 'Machine pistol 9mm') is asubmachine gun chambered for the9×19mm Parabellum cartridge that is designed and manufactured byBrügger & Thomet.

The MP9 is a development of theSteyr TMP which was purchased fromSteyr in 2001. Differences from the TMP include a stock that folds to the right side of the weapon, an integratedPicatinny rail, and a new trigger safety.

The MP9 is aselective-fire submachine gun. It uses 15, 20, 25, and 30 round transparent polymer detachable boxmagazines. It has three safeties: an ambidextrous safety/fire mode selector switch button (manual safety), atrigger safety, and adrop safety.

The MP9 is made of polymer and also corrosion-resistant. Its design and ease of operability allows the user to holster the weapon like amachine pistol orpersonal defense weapon for rapid deployment in self-defence.^[9]

Later variants (TP9-N, TP9-US, MP9-N, MP45) have new designed ambidextrous two/three-position selectors. The old Steyr style cross-bolt push button selectors are replaced with new "HK" style selectors.^[5]

The TP9 is a semi-automatic civilian variant of MP9.^[11][12]

Its design is similar to the Steyr SPP, but its differential feature is an underbarrelMIL-STD-1913Picatinny Rail, which is installed in front of the trigger guard, in place of the forward grip. This was to done to comply with US firearm import laws.

The TP9SF is superficially similar to the TP9, though it isselective-fire rather than semi-auto only.

With the TP9-N B&T decided to add an empty socket (which also includes the hand-stop) for the foregrip, instead of a picatinny rail as with the old TP9.

It also comes without a stock, but with an attachment point that can fit various folding or telescoping braces and stocks, should a customer decide to register it as a short barreled rifle and add one.

The regular TP9-N is identical to the MP9-N, just without full-auto capability.

A version chambered in6.5×25mm CBJ was developed in 2010, requiring only a barrel change to accept the new caliber.^[4][13]
