Constitutional carry; expanding scope of persons authorized to transport firearms in vehicles; emergency.

HB 1004 allows most Oklahoma residents aged 21 or older to carry concealed or unconcealed firearms without a state license ("constitutional carry"). It also permits 18-20-year-olds who are U.S. military members, veterans, or honorably discharged personnel to carry firearms without a license, expanding prior exceptions. The bill modifies Oklahoma's gun laws to remove the requirement for a handgun license for eligible adults while maintaining prohibitions for those convicted of specific offenses like domestic violence or drug crimes. This directly affects all eligible Oklahomans seeking to carry firearms in public, shifting the legal standard from licensed carry to license-free carry for qualifying individuals.
