Are stun guns legal in Missouri? Generally, yes. Missouri does not impose a general statewide prohibition on ordinary civilian stun-gun possession, and it does not establish a separate stun-gun ownership permit. However, carrying or using an electrical self-defense device may be subject to other laws, particularly if the device qualifies as a weapon readily capable of lethal use.
Missouri’s weapons statutes distinguish firearms from other weapons and address concealed carry in certain restricted locations, threatening displays, and unlawful use. Understanding those distinctions is more useful than assuming that every stun gun is legal in every situation.
For a broader comparison of state laws, see our guide to stun gun legality in the United States.
Missouri’s principal weapons provisions appear in Chapter 571 of the Revised Statutes of Missouri.
Section 571.010 defines several categories of weapons, including firearms, blackjacks, knives, and projectile weapons. It does not establish a separate, comprehensive licensing category for ordinary contact stun guns.
Section 571.030 addresses unlawful use of weapons. Its provisions include carrying certain concealed weapons into specified restricted areas and exhibiting a weapon readily capable of lethal use in an angry or threatening manner.
The distinction is important: a stun gun is not automatically a firearm under Missouri law, but that does not mean every electrical device is exempt from every weapons restriction.
Missouri does not establish a separate statewide permit specifically for ordinary stun-gun ownership.
Chapter 571 does not impose a general licensing requirement merely because a person possesses an ordinary contact stun gun for lawful purposes.
However, other laws or court orders may affect an individual’s eligibility to possess particular weapons. The classification of the device and the circumstances of possession still matter.
Missouri generally permits possession and carrying of ordinary stun guns for lawful purposes, but the rules should not be reduced to an unrestricted right to carry every electrical weapon everywhere.
Section 571.030(1) addresses carrying concealed certain weapons readily capable of lethal use into areas where firearms are restricted under Section 571.107.
Whether this provision applies to a particular electrical device depends on the device’s characteristics and whether it falls within the statute’s relevant language.
In addition, public institutions, employers, and private property owners may have applicable security rules.
Missouri does not establish a conventional concealed-carry permit requirement specifically for every ordinary stun gun.
However, the state’s unlawful-use-of-weapons statute can apply to certain concealed weapons in specified restricted areas.
A concealed-carry permit for firearms should not be treated as a blanket authorization to bring any electrical weapon into a restricted location.
Consumers should consider the particular device, location, and applicable restrictions before carrying a stun gun concealed.
Conventional stun guns and projectile-based TASER-style devices operate differently.
A contact stun gun generally requires direct contact to deliver an electrical shock. Certain TASER-style devices can deploy electrical probes from a distance.
Missouri Section 571.010 defines a firearm as a weapon designed or adapted to expel a projectile by the action of an explosive. An electrical device that launches probes without using an explosive does not automatically satisfy that firearm definition.
However, the statute also defines other weapon categories, including projectile weapons. Whether a particular device falls within a statutory category depends on its design and capabilities.
Buyers should not assume that every device marketed as a TASER or stun gun has identical legal treatment.
Missouri’s general Chapter 571 weapons provisions do not establish a clearly stated universal minimum age of 18 for possession of every ordinary contact stun gun.
That does not mean every sale, transfer, or use by a minor is automatically lawful. Other legal circumstances and retailer policies may apply.
Retailers commonly impose their own age-verification requirements. Parents, guardians, and younger buyers should confirm applicable rules before purchasing or transferring an electrical self-defense device.
Missouri Section 571.070 prohibits certain individuals, including people with qualifying felony convictions, from possessing firearms.
However, that statute specifically addresses firearms. Under Section 571.010, a firearm is a weapon designed or adapted to expel a projectile by the action of an explosive.
Consequently, the firearm prohibition should not automatically be described as a blanket ban on every non-firearm electrical self-defense device.
Other laws, court orders, supervision conditions, or individual circumstances may still impose restrictions. Anyone with a criminal conviction or uncertainty about their eligibility should consult a qualified Missouri attorney before acquiring a device.
Missouri law identifies certain locations where concealed firearms are restricted. Section 571.107 includes courthouses, schools, certain government facilities, and other specified places.
However, Section 571.107 principally addresses concealed firearms and the limits of concealed-carry permits. It should not automatically be interpreted as imposing identical restrictions on every ordinary stun gun.
Schools, universities, and educational institutions may have weapons restrictions under state law and their own policies.
Before bringing an electrical self-defense device onto school property, verify the institution’s rules and whether any applicable weapons statute covers the device.
Courthouses and government buildings may have controlled entrances, screening procedures, and restrictions on weapons.
Do not assume that a device is permitted merely because it is not classified as a firearm. Check the applicable facility rules before entering.
Private businesses, workplaces, concert venues, and event organizers may restrict weapons on their premises.
Property policies and applicable laws should be reviewed before bringing a stun gun into a venue or workplace.
Missouri does not impose a general statewide stun-gun transportation permit requirement for ordinary civilian possession.
However, vehicle possession may be affected by the device’s classification, the location, and other applicable laws.
Firearm-specific transportation rules should not automatically be applied to non-firearm electrical devices. Travelers should verify the requirements applicable to their particular equipment and circumstances.
Lawful ownership does not authorize threatening or unlawfully using an electrical weapon against another person.
Section 571.030(1)(4) addresses exhibiting a weapon readily capable of lethal use in an angry or threatening manner in the presence of another person.
Depending on the circumstances, other Missouri criminal laws concerning assault or threatening conduct may also apply.
Whether using a stun gun constitutes lawful self-defense depends on the threat, the circumstances, and the applicable law governing defensive force.
Electrical self-defense devices can cause injuries and are not guaranteed to incapacitate an attacker. They should not be described as harmless or as a substitute for sound judgment and personal safety planning.
Travelers should verify the laws applicable to their particular device, the places they intend to visit, and any other states along their route.
For air travel, TSA prohibits stun guns in carry-on baggage. Certain devices may be accepted in checked baggage subject to special instructions, airline policies, and battery-safety requirements.
Our guide to flying with stun guns explains additional considerations. Compliance with TSA rules does not establish that possession or carrying is lawful at the destination.
These official Missouri statutes provide the starting point for understanding the state’s weapons definitions, possession restrictions, and unlawful-use provisions:
Section 571.030 was amended effective August 28, 2026. Readers should consult the current statute and distinguish provisions expressly governing firearms from those addressing other weapons.
Generally, yes. Missouri does not impose a general statewide ban on ordinary civilian stun-gun possession. However, carrying and using a device may be subject to other laws depending on its classification, the location, and the circumstances.
Missouri does not establish a separate statewide permit specifically for ordinary stun-gun ownership. Other applicable laws or restrictions may still affect particular devices or individuals.
Missouri does not impose a conventional concealed-carry permit requirement specifically for every ordinary stun gun. However, Section 571.030 may restrict certain concealed weapons readily capable of lethal use in specified locations.
Missouri’s general weapons statutes do not establish a clearly stated universal minimum age of 18 for possession of every ordinary contact stun gun. Other laws, circumstances, and retailer age policies may apply.
Missouri Section 571.070 specifically restricts firearm possession by certain individuals. It should not automatically be interpreted as prohibiting every non-firearm electrical device. Other legal restrictions or individual circumstances may still apply.
Missouri generally permits lawful defensive force, but whether using a stun gun is justified depends on the circumstances and applicable self-defense law. Lawful possession does not automatically justify threatening or using force against another person.
Ordinary stun guns are generally legal to possess in Missouri without a separate stun-gun ownership permit. However, Missouri’s weapons statutes, location-specific restrictions, and laws governing unlawful threats or use of force remain important.
Before purchasing, carrying, or using an electrical self-defense device, verify its legal classification and any restrictions that apply to your circumstances.
This article provides general legal information, not individualized legal advice. Laws and legal interpretations can change. Before purchasing, possessing, or carrying a stun gun in Missouri, verify current state and local requirements. Consult a qualified Missouri attorney if you have questions about your eligibility, the classification of a particular device, or your circumstances.
