I really don’t think a gun is useful for true self defense. Have you checked out target focus training? They are true survival teachers. In real life you won’t have time to get out your gun when confronted with violence … What will ensure your survival is your will to meet violence with extreme violence with whatever is at hand even if it comes down to grabbing the dudes face and biting off his nose while he’s stabbing you By the time you draw the fights probably over if the dude intends you harm.
Gun ownership for personal defense in general is weak. Real defense involves permanently disabling the other person with hands feet teeth and the objects around you.
This is why it is a bad idea to ever fight with anyone no matter how small or weak. If you are ready to fight to the death you will have a better chance of winning than if you have a gun in a leg holster. Taking out an eyeball with a thimb for defense is a better skill than going to a shooting range.
I don’t have the stomach for posers with guns who think they are tough. Give me a quiet street fighter who will bite your face off any day.
