The Bureau of Alcohol, Tobacco, Firearms and Explosives estimates that about 9 million guns were manufactured in the United States in 2014, compared with 5.5 million produced in 2010. According to FBI data, firearms were used in 41 percent of all U.S. robberies—far more than any other weapon category.
