Senate Bill 1610 would make the Colt single-action Army revolver the official state firearm. If approved and signed into law, the measure would follow the lead of Utah, which in March adopted the Browning M1911 semiautomatic pistol as its official firearm. Arizona lawmakers say the historic revolver would honor Arizona鈥檚 Wild West heritage.
