...Also, if you're so inexperienced as a handgun shooter, that the biggest round you can effectively handle is a 9mm, you have no business using a hand gun for defense purposes. It doesn't take that much training to become proficient with any semi-auto pistol...
So if my wife/daughter/elderly mother/grandfather etc. etc.is effective with a 9mm but but not so much with the larger calibers they should just dump the pistol all together,be handed a 12 ga. pump and told to suck it up? Got it.
