Brian Rich/Sun-Times file SPRINGFIELD — Dueling gun control bills are heading for a showdown on the floor of the state Legislature. One would require potential gun owners to be fingerprinted to obtain a Firearm Owner Identification Card, entail more frequent renewal of the card and mandate background checks for the private sale of firearms. The other bill is designed to lessen the strain on gun owners and the Illinois State Police by automatically renewing and digitizing FOID cards in Illinois. It has the backing of the police agency, which issues the cards and handles background checks for gun purchases. Both bills seek to reform and improve the FOID card, which Illinois residents must have to legally own firearms or ammunition. But each side accuses the other of missing the target.
