O/T Firearms 101: Have some questions on laws-

Carrying in a vehicle, as you know by now, varies from State to State. The issue is one of accessibility. Here in Az., an unholstered weapon in say, a door panel would be concealed & Az. does not have reciprocity with Fla. so your Ccw would be useless. A HOLSTERED weapon is fine as it's not considered "readily accessible"in Az. See how weird this can get? If it were me, I'd have the weapon holstered, in a glove box or console & if stopped, tell the Officer you have it. While it may cause some additional questioning, if you don't tell him & he finds it somehow, he'll take it as you were were trying to hide it & probably not be real forgiving.
