What state?
In Arizona for example, you could have an arsenal in your front seat. Sling a rifle over your shoulder and a strap a pistol on your hip when you get out of the car. As long as you can legally own the gun, you can carry it openly or concealed with no permit needed.
I thought you had to have 2° of separation. Like the gun in the glove compartment and the magazine under the seat, or a loaded gun in the glove compartment but in a holster.
