I was not endorsing any caliber as a "home defense weapon". What I was trying to find out are statistics on which gun is used most often in crimes. Maybe I did not word my thread clearly. The FBI's web site has a lot of facts and figures, but I could not find one dealing with a particular type or caliber. I will say that we take in to custody more small revolvers than semi-autos from offenders. Most are old. If we do take a semi-auto, it isnot a popular,such as a S&W, Ruger, etc.make, of course even an unkown brand cankill you. We take mostly 9s, 25s, and 22s in that order.
