Owens notes in his July 8 BearingArms.com blog that Illinois has, perhaps, the most onerous and restrictive firearms regulations in the nation. The buy a gun in Illinois, residents must first obtain a Firearm Owners Identification (FOID) card, which is issued by the Illinois State Police only after federal and state background checks. Then, for every sale made by a Federal Firearms License (FFL) holder, the purchaser must complete ATF Form 4473. The FFL will use that information to conduct background checks: The NICS (National Instant Criminal Background Check System) background check administered by the FBI. This same information also goes to the Illinois State Police to run another background check to ensure the purchaser hasn’t become a prohibited person since their FOID card was originally issued.
