Gun owners in the only state still banning concealed weapons would win that right under a plan approved by the Illinois House on Friday.
This would bring the state into compliance with a federal appeals court's ruling that ordered the state to adopt a concealed-carry law by June 9.
But the plan would curb local firearms regulations like Chicago's ban on assault-style weapons.
That's a deal-breaker for Chicago Mayor Rahm Emanuel, who backs tough restrictions to curb gun violence in the nation's third largest city.
Even with those tough restrictions, Chicago has one of the highest gun violence rates in the country.
Gun rights supporters say that this bill would make for a uniform approach across the state.
If the state legislature does not pass concealed carry rules then each municipality could pass its own, meaning that there could be 220 different laws across the state.
The measure would require Illinois State Police to issue a permit to any applicant who has a Firearm Owners Identification card, completes required training, passes a background check, and pays a $150 fee.
Guns would be prohibited, including mass-transit buses and trains, which was a demand of Chicago Democrats.
Illinois is being forced to adopt a concealed carry law because the 7th U.S. Circuit Court of Appeals ruled that the state's ban on concealed carry was unconstitutional.
