As a body of knowledge, all these handgun effectiveness studies are a bunch of crap. They give people who like to demonstrate how smart they are something to base their arguments on. They give people who like to play with guns an opportunity to do it extensively, usually with someone else footing the bill and usually someone paying them to do it.
Within reason, the only factor that matters is the man behind the gun, his skill and his willingness and resolve to prosecute the encounter.
Iron Truth, especially the 'willingness and resolve' point.
