Proposes a constitutional amendment relating to firearms

HJR 158 proposes a constitutional amendment in Missouri that would guarantee the right to bear arms for self-defense in one's home, family, or property, stating this right is unalienable and any restrictions would require strong justification. It allows cities and counties (including St. Louis and Kansas City) to create local firearm regulations via ordinances, such as requiring permits with cost-based fees (capped at 5 years), background checks, and exemptions for law enforcement, judges, and security personnel. The amendment explicitly permits restrictions only for convicted violent felons or individuals deemed a danger to self/others by a court, while requiring local rules to comply with federal law and Supreme Court precedent. This would directly affect all Missouri residents, particularly regarding local gun ownership rules and enforcement of firearm-related ordinances.
