Personally I have seen what even Tulammo can do at close to moderate ranges, so I wouldn't feel disarmed if someone tossed me a mag of it during a fight.
That said, one reason I lean towards Federal HST and Speer Gold Dots in my carry pistol is because many police agencies have adopted them in their service. That way if by some random act of the fate a lawyer asks me what type of ammo I used in a defensive shoot I can always respond with "the same type we issue to the police." So, it may be worth looking into what LEOs carry. I think some also carry federal and Gold Dots in their rifles as well.
