Proposes a constitutional amendment relating to firearms

HJR 28 proposes a constitutional amendment to replace Missouri's current Section 23 regarding firearms. It would explicitly protect the right to keep and bear arms for defense of home, person, family, and property, requiring any restrictions to undergo "strict scrutiny" and obligating the state to protect these rights. The amendment also allows counties and cities (including St. Louis and Kansas City) to adopt local ordinances regulating firearm possession, carrying, or transfer - subject to specific limits like charging only cost-covering permit fees, requiring background checks via federal systems, and capping penalties at $1,000 fines or 1 year in jail. It explicitly preserves restrictions for convicted violent felons and individuals found by court to pose a danger due to mental health issues. The amendment requires voter approval in 2026 or a special election.
