Bear44, I respect your opinion, but you are so far away from what really matters on this, it is hilarious. OF COURSE, the point is to kill the aggressor, what other point is there. I do not believe that we will get the opportunity to choose whether we can kill the aggressor before they do damage or kill the aggressor after damage is done. Since the guns you dislike will kill the aggressor, they have to be defined as SD guns, whether you like them or not. You did not present any facts to back up your statement, just your opinion. Like I said, I can respect your opinion, but I take it as just that, your opinion. I don't agree. A carried gun is a SD gun. A gun left at home, is worthless regardless of the caliber.
Ayoob, Marty Hayes, etc. are all very consistent that, especially in a civilian context, the intent should be to stop the threat.... not kill them.
If they happen to die so be it but it's recommended not to state that was your intent in shooting them.
