Look for the lue poles.
Illinois does not allow concealed carry. I get around this the best I can by keeping my side arm in my truck (I make sure my truck doesnt appear to be worth breaking into). I just follow the laws describing how to legally transport a weapon via vehicle. It doesn't exactly make for lightning speed if I'd ever need it, but its better than nothing. In this case the laws are the same for pistols and long guns. Heck, all I have to do to transport my AR is unload it and dismantle it to a "non-firing state" (shotgun style). It takes a full 5 seconds to put it back together and load it.
I'd look into that if you don't have any other choices.
