MP9 Gun represents the latest advancement in personal defense weapons. This weapon is the world’s lightest 9 x 19 mm select-fire weapon, ideal for surveillance teams, vehicle crews, CQB, SWAT teams and as a PDW, surpassing all other submachine guns in size, weight, and flexibility. This advanced, ambidextrous weapon is also available in semi-automatic only operation for the civilian market as the TP9.
The TP9 is a semi-automatic civilian variant of this weapon. Its design is similar to the Steyr SPP, but its differential feature is an underbarrel MIL-STD-1913 Picatinny 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, though it is selective-fire rather than semi-auto only. A version chambered in 6.5×25mm CBJ was developed in 2010, requiring only a barrel change to accept the new caliber.
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. 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. This version is named the TP9-US. The regular TP9-N is identical to the MP9-N, just without full-auto capability.
