What's Happening With Suppressors In Missouri SB273

SB 273, which, IF ENACTED, modifies provisions relating to firearm suppressors in MISSOURI, is currently a hot topic and keeps our phones ringing here at the shop. So we at Tactical Shit wanted to break it down for you all so we can hopefully shed some light on the confusion.

Current Bill Summary SB 273

This act repeals prohibitions on the possession and selling of firearm silencers. Additionally, this act provides that after August 28, 2025, the offense of knowingly possessing or selling a firearm silencer shall not be prosecuted. If a criminal action is pending regarding a firearm silencer, such action shall be dismissed.
This act also provides that a firearm suppressor that is manufactured in this state and remains in this state shall not be subject to federal law or federal regulation. A firearm suppressor manufactured and sold in this state shall have the words “Made in Missouri” clearly stamped on it. The Attorney General shall also seek a declaratory judgment on the constitutionality of this act from a federal district court on behalf of anyone in this state manufacturing firearm suppressors.
Finally, this act shall apply to all agencies, boards, municipalities, and courts of this state. No entity in this state shall adopt any rule or regulation that allows the enforcement of federal laws regarding firearm silencers. Any entity which adopts any such rule or regulation shall not receive state grant funds. Any citizen with evidence of a violation of this act may submit a complaint to the Attorney General. The Attorney General may file a writ of mandamus pursuant to any citizen complaint.

According To LegiScan

Status: (Introduced) 2025-02-13 – Second Read and Referred S Transportation, Infrastructure and Public Safety Committee [SB273 Detail]

Meaning No, Nothing Changes Today, HOWEVER, would this bill come to fruition, this is what it means in layman’s terms.

Decriminalization: As of August 28, 2025, possessing, manufacturing, transporting, repairing, or selling a firearm suppressor will no longer be a criminal offense in Missouri.

Prohibition of Federal Enforcement: State and local government entities are prohibited from enforcing federal regulations on suppressors that are more restrictive than Missouri state law.

No Prosecution of Pending Cases: Any criminal actions pending regarding firearm suppressors will be dismissed as of August 28, 2025.

“Made in Missouri” Label: Firearm suppressors manufactured and sold in Missouri must have the words “Made in Missouri” clearly stamped on them.

Legal Status: The Attorney General will seek a declaratory judgment on the constitutionality of the act from a federal district court.

Definition of “Generic and Insignificant Part”: The bill defines this as an item with manufacturing or consumer product applications other than inclusion in a firearm suppressor, such as a spring, screw, nut, or pin, according to the Missouri House of Representatives.

State-Specific Manufacturing: Suppressors manufactured entirely within Missouri using primarily local materials and marked “Made in Missouri” will be exempt from federal regulation.

Citizen Enforcement Mechanism: Citizens would be allowed to file complaints with the Missouri Attorney General if local entities attempt to enforce federal suppressor regulations. Non-compliant entities could face penalties, including the loss of state grant funds.

This would only pertain to the individual, and at the state level, meaning that it would only count at the state level. One would STILL however, be in violation of a FEDERAL level law, trumping the state.

For example, if you are pulled over and interact with a FEDERAL LEVEL entity, and you have a “Missouri Only Non-serialized Suppressor”. You are still most likely going to be charged with a federal crime. This is because the NFA (National Firearms Act) still pertains to items like suppressors, provided they are properly registered through the ATF.

As a reminder, we aren’t lawyers , and the people over at Firearms Policy Coalition ARE, so before you go making your own, know the risks.

IN Summary

If enacted, SB 273 would position Missouri as a state with some of the most permissive suppressor laws in the country. However, it’s important to note that while the bill seeks to exempt Missouri-made suppressors from federal regulation, the federal government may still assert its authority under the Commerce Clause of the U.S. Constitution. Therefore, individuals and manufacturers should exercise caution and consult legal counsel before engaging in activities that may conflict with federal law.
