Hi there uberingram,
In Arizona you may carry any firearm loaded on your side so long as
A. At least 2 inches of the holster or firearm are visible.
B. It must be in a holster.
C. You must be at least 18 years of age or have written permission from a legal gardian.
D. You can conceal it any where in your auto so long as it is in a holster and not concealed on your person. example: In your glove box, in the side compartment of the door, under the seat, so long as you inform any law enforcement officer that you have it and where it is when asked.
It is also legal to purchase handguns in Arizona without the need for registration, no permit to carry is neede so long as it is OC, no waiting periods. An instant background check is done at the time of purchse and then you can start carying it as soon as you buy it. That's it. Of course you can't carry into a bar, court house and a couple of other pretty obvious places. But a restaurant, grocery store or any other place that does not sell open alcohol is OK. I've even carried to the court house and they will take care of my firearm for me so it isn't stolen from mycar. Just have to make sure you unload it before you go up to the doors, and leave it in the holster. oh, and never take your gun out of the holster unless you are defending yourself, not even to show it to a curious person if your in a public establishment.And in Arizona we recently had a law passed thatallows us to defend our selves with the use of deadly force andself defensegives us the the right to determine such rather than the responding law enforcement office unless the officer can see evidense at the seen that is clearly a case of foul play. But even so its not like other states where your gun and you are kept until the investigation is completed. But I would suggest looking at our state laws to get a better discription of the laws so you can be aware of things I may have over looked. In other words don't take my word for it, I'm not a lawyer or law maker and certainly don't know all! And welcome to Arizona.
