The state firearm is the Colt Single Action Army Revolver.
In April of 2011 Governor Jan Brewer signed Senate Bill 1610 and created Arizona's newest symbol, the State Firearm. Seen by some as the gun that won the west, the Colt Single Action Army revolver was first manufactured in 1873 and continues to made at the factory in Connecticut. -- A.R.S. § 41-860.02
