Proposes a constitutional amendment relating to firearms

This bill proposes a constitutional amendment in Missouri that guarantees the right to bear arms for self-defense, home protection, and lawful duties, stating these rights are "unalienable" and any restrictions must undergo strict scrutiny. It allows counties and cities (including St. Louis and Kansas City) to create local firearm regulations through ordinances, such as requiring permits with cost-based fees (maxing $500), background checks, and penalties up to $1,000 fines or 1 year in jail for violations. The amendment explicitly exempts active/passive law enforcement, judges, security guards, and military personnel from local rules, while permitting restrictions only for convicted violent felons or those deemed a danger due to mental health issues. The measure aims to align with the federal Second Amendment but would override other state laws on local firearm ordinances.
