Bill > SB273

This bill modifies Missouri's laws regarding firearm suppressors (also known as silencers) by creating several new provisions. The bill decriminalizes the possession, manufacture, transportation, repair, or sale of firearm suppressors, effectively making it legal in Missouri as of August 28, 2025. It defines a firearm suppressor as any device designed to muffle a firearm's sound and establishes state-specific manufacturing guidelines, requiring that suppressors manufactured entirely within Missouri and using primarily Missouri-sourced materials are exempt from federal regulations. The bill mandates that Missouri-made suppressors be stamped with "Made in Missouri" and prohibits state and local government entities from enforcing federal regulations on suppressors that are more restrictive than state law. Additionally, the bill allows citizens to file complaints with the Attorney General if local entities attempt to enforce federal suppressor regulations, with potential penalties including the loss of state grant funds for non-compliant entities. The legislation also requires the Attorney General to seek a declaratory judgment confirming the constitutionality of the new suppressor provisions and provides protection for existing or pending criminal cases related to suppressors.
