Really I think the bottom line here is that this is something that is extremely difficult to really scientifically test because we can't just go out and force a bunch of people to get into gunfights of various calibers.
Would you take a .22lr over say, a #2 pencil and Bic Pen?
A .22lr to the nasal ocular junction is a rather effective way to stop an assailant. And usually only takes one shot.
How would a 230gr +9 .45acp been any more effective than the .40 S&W then police were using?
Where is this "nasal ocular junction"? Is that somewhere around Trafalgar?
