CHICAGO (CBS) -- More than 400 guns are off the streets of Chicago, all thanks to a gun turn-in event by the city's police department.
It took officers just four hours to collect the weapons on Saturday at New Life Covenant Church in the Grand Crossing neighborhood.
People received a $100 gift card for every gun they turned in.
B.B. guns, air guns and replicas were exchanged for $10 gift cards.
