Ok like they say on that cooking show..lets kick it up a notch. What is your beliefe in one shot stopping power? What is the minimum calaber you believe is acceptable for self defense? Come on get the soap boxes out and chime in! ME: I do not believe any (Yep ANY too include 50 cal BMG) is capable ALWAYS produecing a 1 stop shot. I believe that no one fires 1 shot and goes..gee mister bad guy are you done...I believe that people shoot untill gun goes click...so for self defense one can use a 32acp or bigger (not a fan of the 25acp) and do just fine as long as they practice with it.
