I always heard that if you wanted to really mess a bad guy up, to shoot him in the head with a .22, because the bullet goes in & then just rattles around inside the skull, pretty much guaranteeing immobilisation. Bigger calibers go through?
I'm not at all knowledgeable about using a gun for SD; hope it doesn't come down to that. Given a choice between using my little .22 revolver and some bad guy stealing my stuff or harming my family, I'm going to use my head & all available cover, and put as many of the 9 available rounds in dude's face.
I feel I could probably be somewhat less judicious with the 17 rounds in my 9mm, however.
