Design
The MP9 is a development of the Steyr TMP, which was purchased from Steyr in 2001. Differences from the TMP include a stock that folds to the right side of the weapon, an integrated Picatinny rail, and a new trigger safety.
The MP9 is a selective-fire submachine gun. It uses 15, 20, 25, and 30 round transparent polymer detachable box magazines. It has three safeties: an ambidextrous safety/fire mode selector switch (manual safety), a trigger safety, and a drop safety.
The MP9 is made of polymer and is also corrosion-resistant. Its design and ease of operability allow the user to holster the weapon like a machine pistol or personal defense weapon for rapid deployment in self-defence.[9]
Later variants (TP9-N, TP9-US, MP9-N, MP45) feature new ambidextrous two/three-position selectors. The old Steyr style cross-bolt push button selectors are replaced with new "HK" style selectors.[5]
Variants
MP9N
Improved MP9 variant, with "N" indicating a NATO-compliant configuration.[10]
MP45
MP9 6.5×25mm CBJ
A version chambered in 6.5×25mm CBJ was developed in 2010, requiring only a barrel change to accept the new caliber.[4][12]
MP9-FX
Training variant.
TP9
The TP9 is a semi-automatic civilian variant of the MP9.[13][14]
Its design is similar to the Steyr SPP, but its differential feature is an underbarrel MIL-STD-1913 Picatinny Rail installed in front of the trigger guard, in place of the forward grip. This was to be done to comply with US firearm import laws.
TP9SF
The TP9SF is superficially similar to the TP9, though it is selective-fire rather than semi-auto only.
TP9-US
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.
TP9-N
The regular TP9-N is identical to the MP9-N, just without full-auto capability.
TP380
A subcompact version of the TP9 in development, chambered in .380 ACP.
