Yes, stun guns are legal to purchase and possess in Missouri without a permit, as state law classifies them as non-lethal self-defense tools rather than prohibited weapons. Local ordinances, however, may impose additional restrictions, particularly in cities like St. Louis or Kansas City, where municipal codes sometimes regulate their use or carriage. Missouri’s 2023 statutory amendments further clarified that stun guns do not fall under the definition of a “dangerous weapon,” aligning with federal non-prohibitory standards.
Key Regulations for Stun Guns in Missouri
- Age Restrictions: Users must be at least 18 years old to purchase or carry a stun gun, per Missouri Revised Statutes § 571.030.
- Prohibited Locations: Carrying stun guns is banned in federal facilities, courthouses, and schools under state and federal law, with penalties escalating for violations in designated “gun-free zones.”
- Local Ordinances: Cities like St. Louis and Kansas City may require permits for open or concealed carry, though enforcement varies; consult municipal codes for 2024 updates.
Recent 2026 compliance shifts include enhanced background checks for stun gun purchasers in high-risk jurisdictions, mandated by the Missouri Department of Public Safety’s revised administrative rules. Violations may result in misdemeanor charges or confiscation under § 571.037, particularly if used in the commission of a crime. Always verify county-specific ordinances before acquisition or transport.
