Sheriff Dart said while a valid FOID card is run to make sure it is valid, but that isn't the case with ammunition.
"Ammunition, you just walk into the store, you show them a card, it's not run, it's not seen to be valid or not," Sheriff Dart said. "They don't run it."
He said that 32,000 people in Cook County have had their FOID card revoked and of them, 20,000 have not turned in their gun or card.
Dart was joined at the news conference by State Representative La Shawn Ford and State Senator Jacqueline Collins.
