Illinois is considering boosting gun control measures, even as its laws are under fire from Second Amendment advocates concerned they undermine constitutional rights.

Illinois is one of two states that require residents to obtain a government-issued license to legally possess or purchase any firearm, giving state police up to 30 days to approve or deny applications. While the New Civil Liberties Alliance is suing to block the Illinois Firearm Owners Identification Card Act, gun rights proponents could find themselves facing yet another hurdle in the coming months, as state Democrats begin to eye a bill that would effectively ban Glocks.
