Notwithstanding any other state law to the contrary, no state agency shall disclose to the federal government the statewide list of persons who have obtained a concealed carry endorsement or permit, including Missouri lifetime and extended concealed carry permits. Nothing in this section shall be construed to restrict access to individual records by any criminal justice agency authorized to access the Missouri uniform law enforcement system.
