Illinois has had legal concealed carry for two years now and, despite predictions to the contrary, the sky has not fallen. Permits cost $150 and are valid for five years, while non-resident permits can be obtained for $300.
The 16-hour training requirement is extensive as Right-To-Carry states go, but Illinois does have strong self-defense laws. The law has a preemption element, so cities cannot opt-out.
Illinois resident permits are recognized in 25 states.
Even the Chicago Tribune had to admit that CCW had gone well. A couple of libs I know were despondent when blood didn’t run in the streets. I told them that if they wanted to find out what kind of war zone Illinois would become all they had to do was cross any of our boarders and they would be in CCW state and could experience it immediately. But you know how well logic works. We had a local network reporting every firearm crime as being committed by a “concealed firearm” trying to convince the steeple that legal CCW were committing them. A bunch of us called them on it and they quit.
How does Chicago figure into this? IIUC it is nearly impossible to get a permit there.
