I am the happy owner of a Witness Match. Mine's a .45, I like mine a lot. Works great for bowling pins.
What little info is out there leads me to believe that Ultra is a model designation no longer in use, at least in the US. Tangfoglio may still be using it in Europe. Or it could've been replaced by an updated version in the current line up. It appears at first glance to be a Witness Match with a few extra goodies. Anything at all like this:
Tanfoglio Ultra match 9 mm
