Open carry is legal in Az but few do it any longer because it's legal to carry concealed with no permit now. Lots of people carry here because of the border situation. The only problem I've seen was one incident at Walmart where a new manager that recently moved from a flaming liberal state called 911 and the cops came and surrounded the guy and walked him out. When asked what he had done all she could say is that he had a pistol and she was sure it was illegal. She didn't realize that this is the wild west and it is legal and encouraged. I like to carry concealed so no enterprising cretin gets the idea that they may want to take my weapon from me because I'm old and weak. Also if there's trouble and you end up inadvertently in the middle of it you don't want to be eliminated as an immediate threat. I want my camoflage (I masquerade as a timid old man) to give me a decided edge because in 1 second or a little less I can ruin the party.
