Missouri Firearm Laws - Complete Guide

Comprehensive analysis of Missouri gun laws, permit requirements, carry regulations, and recent legislative updates for responsible gun owners.

Missouri Gun Laws at a Glance

Missouri is a constitutional carry state. Senate Bill 656 was enacted over a veto and took effect January 1, 2017, changing the offense of unlawful use of a weapon so that carrying concealed is generally legal without a permit except in locations restricted by law. Missouri remains shall-issue for those who want a permit (including extended and lifetime options) for reciprocity and other benefits. The state has strong firearms preemption, broad self‑defense protections (Castle Doctrine and Stand Your Ground), and no registration, purchase permits, or waiting periods.

Constitutional carry (since Jan 1, 2017): Permitless concealed carry for most adults 19+ (18+ for active-duty or honorably discharged military) who are not prohibited persons.
Shall-issue permits available: Standard 5‑year CCW plus 10‑year, 25‑year, and lifetime options.
Strong preemption: State preempts most local firearms regulation; limited local authority to regulate open carry, but not for valid permit holders.
Robust self-defense laws: Castle Doctrine and Stand Your Ground with civil/criminal protections in justified cases.
No registration/permits to purchase: No waiting period; private sales not subject to state background-check mandate.
