Considering this is a new chapter in this saga for IL... perhaps this post should actually be the start of a new thread, up to the mods.
Don't hate me for linking Breitbart... it has the most information from all the links I found talking about the numbers:
4,525 individuals signed up on Sunday alone for their firearms permits, when the State Police first opened the process to all concealed carry applicants.
Illinois State Police spokeswoman Monique Bond said that number is included in Sunday’s total of more than 11,000 people who have signed up because of an early application process that began December 18 and was open to only firearm instructors. Officials told the Sun-Times they expect 350,000 to 400,000 people (about 1,000 per day) will sign up for conceal carry firearm permits this year.
