You dont need a permit to carry open or concealed any longer here in AZ. Also there is no testing/training requirement to get a CCW. Fingerprints and a money order and you have a carry permit.
However, I do keep mine active and attend a refresher course every few years just to stay on top of any changes to the laws and such, which unfortunately is sometimes dependent on the political climate.
I have never seen a secure lobby Bank myself, pretty sure I will not be going to one either. I do my best not to do business with companies that infringe on my rights.
