Steyr introduced their TMP (Tactical Machine Pistol) and its semiauto SPP counterpart in 1989, but it was never a very popular item. After the company was purchased, the new ownership decided to scrap the TMP (along with other low-performing product lines). At that point, Swiss firm B&T purchased the whole project for a nominal one Austrian Schilling and began to develop it themselves. B&T made a number of reliability improvements to the basic design, and perhaps most importantly added a folding stock to what had previously been a machine pistol design. They now offer it as a semiauto civilian pistol or carbine, and as a PDW or submachine gun to military clients. It has been adopted by a number of units around the world in a variety of roles including pilot survival weapon, maritime boarding party armament, and compact special forces SMG.

At Forgotten Weapons I think the most interesting guns out there are the most obscure ones. I try to search out experimental and prototype weapons and show you how they work, in addition to more conventional guns that you may not have heard of before. You’re much more likely to find a video on the Cei Rigotti or Webley-Fosbery here than an AR or Glock. So, do you want to learn about something new today? Then stick around!
