Show attendees shop for handguns at the Western Collectibles & Firearms Gun Show held in Tim's Toyota Center. Guns are big business in Arizona, which has more than 1,200 federally licensed firearm dealers that sell more than 200,000 guns a year and is on track to set a gun-sales record this year. The Bureau of Alcohol, Tobacco, Firearms and Explosives licenses more than 100 Arizona-based makers of guns and gun parts that employ more than 1,000 people.
