The Arizona Senate has approved a bill to allow people with concealed weapons permits to carry a gun into a business that serves alcohol.
The 19-8 vote completes Legislative action on the bill and sends it to Gov. Jan Brewer.
The measure has pitted powerful groups representing gun and bar owners against each other.
It would require bar and restaurant owners who want to ban weapons to post a sign next to their liquor license. Drinking while carrying a weapon would be illegal.
Opponents have said mixing guns and alcohol could cause violence, but supporters argue that people should be able to protect themselves at businesses that serve alcohol.
