We must be getting very close if they are making small technical changes like that.
I'm not sure that would pass a constitutional challenge. Because IL does not allow open carry, they must allow concealed carry. That's the driving force allowing you to get this passed in the first place. As there is a right to bear arms, and some form of bearing is included in that right- I'm not sure they can tack on the extra fees to fix the FOID, and do this and that with mental health reporting, and so on.
