state troopers merely send a notice of the revocation to the cardholder and to local police. By law, the person must send a form to state police listing his or her guns and identifying another active FOID holder who will hold the guns during the revocation.
Police may not seize guns from a revoked FOID holder unless the holder fails to submit the form. Failing to do so is a misdemeanor and authorizes police to search for and seize the guns, but officials say that rarely happens unless the person is stopped for some other violation.
