Guns are selling at unprecedented levels — background checks conducted by the FBI every month this year have hit an all-time high. Background checks don’t correlate directly to gun sales — But they do serve as an important indicator… Since there are no industry figures for gun sales. Mass shootings in the last several years have helped drive gun sales. Gun buyers worry that every mass shooting will prompt more restrictive gun control laws. If Hillary Clinton is elected president, she says she plans to expand background checks, restrict "military-style assault weapons," and hold gun dealers and manufacturers accountable for gun violence.
