Morally I think if a perfectly innocent person is positive they are about to be punched in the head and have no way out I have no problem whatsoever with them defending with their gun.At what point does being unprovoked punched Justify using deadly force to defend yourself?
The problem is in court "He couldn't take a punch and had to get his gun?!" etc. etc.
Like you said, one hit you're out. You can die. Has happened, does happen. Not very uncommon. Can kill you, or give you a brain injury, or knock your head onto concrete, etc.
