Arizona's governor has signed a bill designating the Colt Single-Action Army revolver as the state's first official firearm.
Gov. Jan Brewer signed the bill without comment on Thursday. Legislative supporters argued that the designation was appropriate because the revolver was widely used during Arizona's territorial days.
Opponents say it was inappropriate to give the official designation to an out-of-state company's commercial product. Colt is based in Connecticut.
Democratic Rep. Albert Hale also says the gun was an instrument of destruction that was used against Native Americans.
