Modifies provisions relating to firearms

SB 1693 modifies Missouri's firearm laws by creating new offenses for unlawful transfer and possession. It prohibits selling, giving, or delivering firearms to individuals who are prohibited under Section 571.070 - such as felons, people on the No Fly List, those intoxicated, or members of terrorism groups - while adding specific rules for transfers to minors without parental consent. Unlawful transfer to prohibited individuals is a class E felony, while other violations (like reckless sales to minors) are class A misdemeanors. Unlawful possession of a firearm by prohibited individuals (e.g., felons, fugitives, or terrorism group members) is a class C felony, escalating to class B if there’s a prior conviction. The bill does not apply to antique firearms.
