Modifies provisions relating to firearms

HB 690 is a definitional bill that updates Missouri's firearm law by creating clear, standardized definitions for various weapons and related terms. It defines terms like "antique firearm," "concealable firearm," "military-style semi-automatic firearm," "knife," and "projectile weapon" to clarify what constitutes specific categories under state law. The bill does not create new restrictions but establishes consistent terminology for enforcement and legal interpretation. These definitions will directly affect law enforcement, courts, and anyone subject to Missouri's firearm regulations. The bill is currently in committee referral for review during the 2025 legislative session.
