Illinois gun shops are bracing for disruption as the Illinois State Police (ISP) prepares to take down its Firearm Owner’s Identification (FOID) verification system for maintenance. The planned outage, set from 2 p.m. Tuesday, May 20, through 4 p.m. Wednesday, May 21, will prevent retailers from validating FOID cards — effectively halting all legal ammunition and firearm sales during that time.
