ATW525,
The problem arises when you revert to what you practice. I fully agree that it is better you than him, but I don't want a good shoot to turn into a criminal case against me. While you may tout the phrase "better judged by 12 than carried by 6", I believe there is a third option which is neither being judged by the 12 or being carried by the 6.
I guess this is when we start having debates about why anything less than a .45 acp is useless and why anything less is asking for a failure to stop. Then i expect someone to say that handguns are useless and that only shotguns and rifles are of any defensive value. I certainly hope it doesn't go down that path...
