The Second Amendment Preservation Act; create to provide that the Legislature preempts local firearms ordinances.

HB 255, the Second Amendment Preservation Act, prohibits Mississippi cities and counties from creating their own laws about firearms, ammunition, or related items. It invalidates all existing or future local firearm regulations unless they exactly match specific state laws on concealed carry, open carry, and firearm discharge rules. The bill also prevents local governments from suing firearm manufacturers or dealers over lawful sales, though it does not block lawsuits for negligence or defects. This law ensures state-level regulation replaces local ordinances for all firearm-related matters in Mississippi.
