Some states don’t require a permit at all for open carry, or concealed carry.
Cite me one state that allows for concealed Carry without requiring a permit ...
Arizona
You’re late.....already been noted.
Let me point out here (as I did above) that there is NO RECIPROCITY WITH OTHER STATES if you go the “no permit” route.
Others WITH PERMITS will be entitled to carry concealed in those other states with reciprocity - while those people with no permits WILL NOT BE ALLOWED to do so in those other states.
