The biggest problem I can see with the 5.7 is that, as best I can tell, there have been one or two well-documented incidents of a bad guy getting decisively piled up with the round. Never mind that, given the shot placement, the same results would have occurred if the officer had been shooting a Mk.II loaded with CCI Stingers, the anecdotes get passed around as proof of the death-ray-like nature of the round.

Yeah, but at least that gun works.
