On Monday, a federal judge declared that the city's ban on gun sales is unconstitutional.
Thursday the mayor indicated he would not appeal the ruling.
Instead he wants time for Chicago to work on a gun sale law.
"I've asked the court counsel to go to court to ask for 6 months," Emanuel said. "Allow us to come up with a responsible way to implement within their strictures, which is to allow gun shops in the city of Chicago, but in a way that doesn't undermine the work that we are trying to do."
The goal of the law would be to keep guns out of the hands of criminals or straw purchasers.
