21.750. 1. The general assembly hereby occupies and preempts the entire field of legislation touching in any way firearms, components, ammunition and supplies to the complete exclusion of any order, ordinance or regulation by any political subdivision of this state. Any existing or future orders, ordinances or regulations in this field are hereby and shall be null and void except as provided in subsection 3 of this section.

No county, city, town, village, municipality, or other political subdivision of this state shall adopt any order, ordinance or regulation concerning in any way the sale, purchase, purchase delay, transfer, ownership, use, keeping, possession, bearing, transportation, licensing, permit, registration, taxation other than sales and compensating use taxes or other controls on firearms, components, ammunition, and supplies except as provided in subsection 3 of this section.
3. Nothing contained in this section shall prohibit any ordinance of any political subdivision which conforms exactly with any of the provisions of sections 571.010 to 571.070, with appropriate penalty provisions, or which regulates the open carrying of firearms readily capable of lethal use or the discharge of firearms within a jurisdiction, provided such ordinance complies with the provisions of section 252.243.
4. The lawful design, marketing, manufacture, distribution, or sale of firearms or ammunition to the public is not an abnormally dangerous activity and does not constitute a public or private nuisance.

No county, city, town, village or any other political subdivision nor the state shall bring suit or have any right to recover against any firearms or ammunition manufacturer, trade association or dealer for damages, abatement or injunctive relief resulting from or relating to the lawful design, manufacture, marketing, distribution, or sale of firearms or ammunition to the public. This subsection shall apply to any suit pending as of October 12, 2003, as well as any suit which may be brought in the future. Provided, however, that nothing in this section shall restrict the rights of individual citizens to recover for injury or death caused by the negligent or defective design or manufacture of firearms or ammunition.
6. Nothing in this section shall prevent the state, a county, city, town, village or any other political subdivision from bringing an action against a firearms or ammunition manufacturer or dealer for breach of contract or warranty as to firearms or ammunition purchased by the state or such political subdivision.
