Maxon is currently already in Desplaines, and just got approval to move to another location in Desplaines.
Shore Galleries in Lincolnwood is looking to expand as well and is seeking Lincolnwood township approval to do so. They had a meeting July 17th, but I do not know the outcome of that meeting.
Have you tried the new Article II gunshop in Lombard? Owned by the same owner of Gunworld previously on Irving Park Rd before the Ohare expansion? I haven't been there myself but I hear good things. Amazing the progress we are making in Illinois when it comes to firearms.
