Rem,
Man, I'd love to be in your situation..."gonna get something, but what?"...
I'd like to point out on your comment about the 5.7, yeah, he may "run off" at 50 yards after being hit, but he's still got a hole through his ass and I can bet you that he "ain't" feeling too hot either!
A 50 yard pistol shot is awesome and the 5.7 (from what IP describes) can serve up that core-bonded sandwich with ease. I can also bet you that whatever he was doing prior to being shot won't be duplicated after the fact! 
However, I am on the .45 bandwagon. Can't get much better "proven" stopping power! HK, Sig...the choices are endless. Post up pics of what you get.
