Brügger & Thomet MP9

The Brügger & Thomet MP9 (Maschinenpistole 9mm, German for "machine pistol") is a submachine gun chambered for the 9×19mm Parabellum cartridge that is designed and manufactured by Brügger & Thomet.

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.

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.

A version chambered in 6.5×25mm CBJ was developed in 2010, requiring only a barrel change to accept the new caliber.

[5] 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.
