The state Senate voted 41-17 Tuesday to override Gov. Pat Quinn's veto of the concealed carry legislation lawmakers sent him. The House took the same action earlier in the day.
The Chicago Democrat's amendatory veto suggested changes to the delicately negotiated initiative - changes that anti-violence activists embraced.
Quinn wanted guns banned from any establishment that serves alcohol and wanted to limit gun-toting citizens to one firearm at a time.
Senate President John Cullerton says Quinn's recommendations might be addressed in later legislation.
The Illinois State Police must be ready to accept applications in six months. Officials expect 300,000 to apply in the first year.
