TINLEY PARK, IL - FEBRUARY 13:  Dan Egar helps a customer shop for a handgun on February 13, 2014 in Tinley Park, Illinois. Nationwide, sales of guns and ammunition have dropped about 50 percent from the same period last year when dealers had difficulty keeping their stores stocked as customers bought up supplies fearing increased regulation and restrictions after a series highly publicized shootings.
