I carry a Beretta Model 21 in .22 caliber most of the time. I was out in the desert by myself, stopped to take a leak and realized how vulnerable I was way out there, so I carry more. I have had a permit for about 20 years. You don't need one in Arizona, but getting one is good for going to other states.
I have seen one person killed in a shooting in my life, it happened about 20 feet from me. Believe me, that is at least one too many. It was a single shot to the chest from a .22 pistol. He died within seconds. I think he was 16. As a side thing, I was absolutely amazed at the ability of the press to get every detail of the story wrong.
