I am planning on getting a USP45 with a threaded barrel. I have been scouting out prices I an effort to see if it is cheaper to buy the base model and add the extra parts, or just buy the 45T (I don't need those match sights). To that end, when people say the Tactical has a "match trigger", are they referring to this:

Or just this:
