Mississippi Firearm Preemption

The Headline

Mississippi has one of the strongest firearm-preemption frameworks in the country. Miss. Code Ann. Section 45-9-51 vests in the Legislature exclusive authority to regulate firearm and ammunition possession, sale, transfer, ownership, use, and transportation. Section 45-9-53 and Section 45-9-55 add specific restrictions and remedies. Section 45-9-57 governs the limited discharge-related carve-outs.

Local political subdivisions (counties, cities, towns, villages) may NOT enact or enforce ordinances that regulate firearms, ammunition, knives, components, or related items in ways that the Legislature has not authorized. Local rules that survive are limited to a narrow set: regulating the discharge of firearms within municipal limits (subject to defensive-use exceptions), regulating the carrying of firearms in police, sheriff, or highway patrol stations, jails, detention facilities, courthouses, courtrooms, polling places, and government meeting places (consistent with Section 45-9-101(13)), and regulating use during a parade or demonstration for which a permit is required.

Operative text - Section 45-9-51

Section 45-9-51 reads (in substance): "Subject to the provisions of Section 45-9-53, no county or municipality may adopt any ordinance that restricts the possession, carrying, transportation, sale, transfer or ownership of firearms or ammunition or their components."

Three points:

• The preemption is broad - "any ordinance" - covering not just carrying but also sales, transfers, transportation, and ownership of firearms, ammunition, and components.
• The preemption applies to both counties and municipalities.
• The qualification "subject to the provisions of Section 45-9-53" preserves the narrow categories where local regulation is permitted.

Operative text - Section 45-9-53

Section 45-9-53 enumerates what counties and municipalities may still regulate without violating Section 45-9-51:

• Discharge of firearms within municipal limits, except in self-defense or defense of another or property.
• Carrying firearms in or onto police, sheriff, or highway patrol stations, detention facilities, jails, courthouses, courtrooms, polling places, or governmental meeting places. This overlaps with the Section 45-9-101(13) statutory restrictions on LTC holders.
• Restrictions on use of firearms during a parade or demonstration for which a permit is required.
• Carrying or possession of firearms in publicly owned buildings or properties (with statutory limitations).

The Section 45-9-53 list is exhaustive. Anything not on it falls under the Section 45-9-51 preemption rule and is barred from local regulation.

Operative text - Section 45-9-55

Section 45-9-55 strengthens enforcement of the preemption by providing remedies:

• Any person adversely affected by a local ordinance that violates Section 45-9-51 may bring a civil action against the local entity.
• The prevailing plaintiff is entitled to recover reasonable attorney's fees, court costs, and other expenses incurred in the action.
• An award of monetary damages is also available where appropriate.

The fee-shifting provision is significant. It encourages enforcement of the preemption by private citizens and firearms-rights organizations and discourages local entities from enacting overreaching ordinances.

Operative text - Section 45-9-57

Section 45-9-57 addresses limited carve-outs related to the discharge of firearms, supporting the framework in Sections 45-9-51 and 45-9-53.

What localities CAN regulate

Within the Section 45-9-53 carve-outs, local entities may:

• Regulate the discharge of firearms within municipal limits. Most Mississippi cities and towns have ordinances prohibiting the discharge of a firearm within municipal limits except in self-defense or for lawful sporting purposes at a designated range. These ordinances are preserved by Section 45-9-53.
• Prohibit firearms in police stations, sheriff offices, highway patrol stations, jails, detention facilities, courthouses, courtrooms, polling places, and government meeting places. This is the local-government parallel to Section 45-9-101(13).
• Restrict firearms during permitted parades or demonstrations. The restriction tracks Section 45-9-101(13)'s parade-and-demonstration provision.
• Regulate possession or carrying in specific publicly owned buildings or properties, subject to statutory limits.

What localities CANNOT regulate

By force of Section 45-9-51, local entities CANNOT:

• Ban or restrict the sale of firearms within municipal limits.
• Ban or restrict private firearm transfers.
• Require local registration of firearms or owners.
• Impose local waiting periods on firearm purchases.
• Require local permits to purchase or possess firearms.
• Ban or restrict specific categories of firearms (assault weapons, semi-automatic rifles, magazines above a certain capacity, etc.).
• Impose local taxes specific to firearms or ammunition.
• Ban open carry, concealed carry, or constitutional carry in public places (subject only to the narrow Section 45-9-101(13) carve-outs).
• Impose specific firearm-storage requirements on private homeowners.
• Restrict where firearms may be carried in privately owned businesses (the business owner may post under Section 45-9-101(13); the city or county cannot mandate that all businesses post or unpost).

Preemption in practice

The Mississippi Supreme Court has applied Section 45-9-51 and Section 45-9-55 broadly to strike down local ordinances that exceeded the Section 45-9-53 carve-outs. The fee-shifting mechanism makes it economically rational for affected residents and firearms-rights organizations to challenge over-reaching ordinances.

Cities and counties that adopt sample firearm ordinances should consult counsel before enactment. The Mississippi Municipal League has issued guidance to its member cities cautioning against adoption of any firearm ordinance not clearly within Section 45-9-53.

Preemption and posted private property

Section 45-9-101(13) gives any "person or entity exercising control over the physical location" authority to post a "carrying of a pistol or revolver is prohibited" notice. This authority belongs to the property owner or operator, not to the local government. A city CANNOT mandate that private businesses post or refrain from posting under Section 45-9-101(13). Posting is the private property owner's choice.

Preemption and posted government property

Posted government property is governed differently:

• Federal property is governed by federal law (e.g., 18 U.S.C. Section 930 for federal buildings).
• State government property is governed by state law and DPS rulemaking under Section 45-9-101(13). State agencies may regulate firearms in state-owned facilities consistent with the Section 45-9-101(13) framework.
• Local government property is regulated by the local entity, but the local rule must stay within the Section 45-9-53 carve-outs. A city hall can post; a city street cannot.

Federal preemption

A separate layer of federal preemption applies to firearms regulation generally. The Second Amendment, as interpreted in District of Columbia v. Heller (2008), McDonald v. Chicago (2010), and New York State Rifle & Pistol Association v. Bruen (2022), constrains both state and local firearms regulations. Mississippi's strong state-law preemption framework prevents most local conflicts before they reach the federal-constitutional question.

Practical guidance for carriers

A Mississippi LTC holder or constitutional carrier should not worry about a patchwork of city-by-city firearms rules. State law preempts. The carrier's analysis reduces to:

• Am I a prohibited person under state or federal law?
• Am I in a Section 45-9-101(13) prohibited place?
• Am I in violation of Section 97-37-1 (carrying concealed in a way not authorized by Section 97-37-1(4) visible-holster carry, Section 45-9-101(24) constitutional carry, Section 45-9-101 LTC, or Section 97-37-7 Enhanced overlay)?
• Am I obeying any private-property posted notice?

Local ordinances generally drop out of the analysis except for the narrow Section 45-9-53 carve-outs.

Practical guidance for local governments

A city or county that wishes to address firearms-related concerns is limited to:

• Discharge-of-firearms ordinances within municipal limits.
• Posted-firearms restrictions in eligible government buildings, jails, courthouses, polling places, government meeting places.
• Parade and demonstration restrictions for permitted events.

Any other firearm-related ordinance risks invalidation under Section 45-9-51 and exposure to Section 45-9-55 fee-shifting. Counsel review before enactment is essential.

Bottom line

Mississippi preemption is robust. The Legislature is the regulator. Local entities have a narrow lane. Carriers can rely on the same state-law analysis everywhere in Mississippi. The Section 45-9-55 enforcement remedy backs the preemption rule with attorney's fees and is the reason local conflicts are rare in practice.
