(a) Except as otherwise provided by state law or as specifically provided in subsection (b), the general assembly preempts the whole field of the regulation of firearms, ammunition, or components of firearms or ammunition, or combinations thereof including, but not limited to, the use, purchase, transfer, taxation, manufacture, ownership, possession, carrying, sale, acquisition, gift, devise, licensing, registration, storage, and transportation thereof, to the exclusion of all county, city, town, municipality, or metropolitan government law, ordinances, resolutions, enactments or regulation. No county, city, town, municipality, or metropolitan government nor any local agency, department, or official shall occupy any part of the field regulation of firearms, ammunition or components of firearms or ammunition, or combinations thereof.

(b) A city, county, town, municipality or metropolitan government is expressly authorized to regulate by ordinance, resolution, policy, rule or other enactment the following:

(1) The carrying of firearms by employees or independent contractors of the city, county, town municipality or metropolitan government when acting in the course and scope of their employment or contract, except as otherwise provided in § 39-17-1313;

(2) The discharge of firearms within the boundaries of the applicable city, county, town, municipality or metropolitan government, except when and where the discharge of a firearm is expressly authorized or permitted by state law;

(3) The location of a sport shooting range, except as otherwise provided in §§ 39-17-316 and 13-3-412. To the extent that a city, county, town, municipality, or metropolitan government has or enforces any regulation of privately owned or operated sport shooting ranges, the city, county, town, municipality, or metropolitan government shall not impose greater restrictions or requirements on privately owned or operated ranges than are applicable to any range located within the same unit of local government and owned or operated by a government entity. A party may challenge any regulation of a sport shooting range that violates this subdivision (b)(3) in the manner described in subsection (g); and

(4) The enforcement of any state or federal law pertaining to firearms, ammunition, or components of firearms or ammunition, or combinations thereof.

(c) The general assembly declares that the lawful design, marketing, manufacture and sale of firearms and ammunition to the public are not unreasonably dangerous activities and do not constitute a nuisance per se.

(d)

(1) The authority to bring suit and right to recover against any firearms or ammunition manufacturer, trade association or dealer by or on behalf of any state entity, county, municipality or metropolitan government for damages, abatement or injunctive relief resulting from or relating to the lawful design, manufacture, marketing or sale of firearms or ammunition to the public shall be reserved exclusively to the state.

(2) Nothing in this subsection (d) shall be construed to prohibit a county, municipality, or metropolitan government 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 such county, municipality, or metropolitan government.

(3) Nothing in this subsection (d) shall preclude an individual from bringing a cause of action for breach of a written contract, breach of an express warranty, or for injuries resulting from defects in the materials or workmanship in the manufacture of the firearm.

(e) Subsections (c) and (d) shall not apply in any litigation brought by an individual against a firearms or ammunition manufacturer, trade association or dealer.

(f) It is the intent of the general assembly that this part is preemptive with respect to the transfer, ownership, possession or transportation of knives and no city, county, or metropolitan government shall occupy any part of the field of regulation of the transfer, ownership, possession or transportation of knives.

(g)

(1) Notwithstanding title 29, chapter 20, a party who is adversely affected by an ordinance, resolution, policy, rule, or other enactment that is adopted or enforced by a county, city, town, municipality, or metropolitan government or any local agency, department, or official that violates this section may file an action in a court of competent jurisdiction against the county, city, town, municipality, or metropolitan government for:

(A) Declaratory and injunctive relief; and

(B) Damages, as provided in subsection (i).

(2) This subsection (g) shall apply to any ordinance, resolution, policy, rule, or other enactment that is adopted or enforced on or after July 1, 2017.
