Wow I guess no one put it up yet but I've seen this site a few times and I think it's quite accurate.
Selection of best ammunition for a defensive handgun
In it the Holy Trinity (9mm, .40 s&w, and .45 acp) all are in the 90% or better range for one shot stops for the best ammo available for each caliber.
Did anyone notice the "Self Defense Rating" this site gives .45acp?

I don't think the study had any controls,it appeared to be a charting of real world situations
where the incidents could occur at any time or place with any handgun and any level of skill
on the part of victim.
