I knew that full auto = machine gun, which as you said trumps all. After all, if that wasn't the case I would be carrying a Glock 18c rather than the 19. I just wasn't sure about the distinction between semi-auto hand gun and semi-auto rifle.
However when I mentioned the TMP, I forgot all about the SPP. Not sure sure how I managed that. But that was the first I had seen a semi auto Mac-10/11. Still not sure what the point is, but...
