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

HB 915, the "Second Amendment Preservation Act," prevents Mississippi cities, counties, and other local governments from enacting or enforcing any ordinances related to firearms, ammunition, or firearm components. It preempts all local laws on these topics, voiding existing or future regulations unless they exactly match specific state provisions (Sections 45-9-51, 45-9-53, 45-9-101, 97-37-7, and 97-37-9 of the Mississippi Code). The bill also limits lawsuits against gun manufacturers for lawful sales, though it preserves individual claims for negligence or defects. This directly affects municipalities that previously regulated gun ownership or sales and alters liability for firearms businesses.
