Senate debate expands into broad gun-policy package; sponsor lays bill over after amendments introduced

Senate consideration of Senate Bill 77 on March 11 opened a prolonged debate that broadened into a multi-part gun-policy package and concluded with the sponsor asking that the bill be placed on the informal calendar.

The underlying substitute described on the floor would allow people with valid concealed-carry permits to carry on public transportation and would lower the minimum age for a CCW endorsement from 19 to 18. The sponsor framed the change as restoring carry rights on buses and trains for law-abiding permit holders: "This legislation would allow those who've undergone CCW training to carry, while they have a valid CCW, to to carry aboard public transportation," the Senate sponsor said.

Floor debate quickly expanded. Senator from Stone offered an amendment (based on his Senate Bill 74) to add private-rights enforcement to Missouri’s firearm preemption law — allowing individuals to sue a city or county that enacts gun-control restrictions stricter than state law and preempting local open-carry restrictions. "What this amendment here is is my senate bill, 74. It would add teeth to Missouri's firearms preemption law," Senator from Stone said. He described the change as creating a cause of action against political subdivisions that violate state preemption.

Senator from Cass then offered an amendment to the amendment that would substantially expand school protection officer authorities, require annual active-shooter/intruder (ACERT) training for school employees, create an enhanced stand-your-ground provision with earlier pretrial review, and remove state restrictions on firearm suppressors (silencers). The sponsor of that amendment described the package as a "constitutional rights package" that, among other changes, would allow retired law-enforcement and military personnel to serve as school protection officers and require intensive training for those officers. He called for legislation to ensure a quicker pretrial hearing in use-of-force cases and argued that suppressors are comparable to a muffler on a car.

Several senators raised concerns during the discussion. Senators representing urban districts and members from both parties questioned the public-safety effects of allowing more firearms in enclosed public-transit environments and asked whether law enforcement had been consulted. One senator asked whether legalizing or broadly authorizing suppressors would hinder gunshot-detection systems used by some cities; the amendment sponsor replied that suppressors still produce sound and that many handguns are not readily compatible with suppressors.

Other senators expressed constitutional and policy arguments. Supporters repeatedly framed the measures as expanding lawful self-defense and protecting constitutional rights; critics raised risks of escalation, the effect on vulnerable transit riders and students, and potential implicit-bias effects in field enforcement.

No final votes were recorded on the main bill or the floor amendments. The bill sponsor later asked that the measure be placed on the informal calendar (laid over) rather than proceed to immediate final action.

Discussion vs. decision The record shows multiple substantive decisions were not made on the floor: several amendments were offered and distributed and some were moved, but none were finally adopted as part of a completed vote during this session. The only formal procedural outcome recorded was the sponsor’s request to place the bill on the informal calendar.

Key items discussed (selected) - Allow concealed carry on public transportation for valid CCW holders; lower CCW age from 19 to 18. - Waive live-fire marksmanship training for active-duty military for CCW issuance. - Allow CCW holders to carry in houses of worship unless asked not to. - Add a private cause of action and stronger enforcement for state firearms preemption (Senate Bill 74 language offered as an amendment). - Expand school protection officer (SPO) eligibility to include employees beyond teachers/administrators, authorize retired law enforcement and military to serve as SPOs, require higher-frequency and higher-hour firearm and active-shooter training, and permit nonlethal projectiles and devices. - Add enhanced "stand your ground" procedures including expedited pretrial review for use-of-force cases. - Legalize possession and manufacture of firearm suppressors at the state level and block local ordinances that attempt to ban them.

What happened next After extended debate and multiple amendments being distributed, the sponsor asked that the bill be laid over and placed on the informal calendar for later consideration. No final amendments or passage were recorded in the transcript excerpt for this session day.

Context note Several senators referenced prior committee work and bills filed in earlier sessions; sponsors said parts of the substitute had bipartisan support in prior years. Senators also tied the discussion to high-profile use-of-force cases invoked during the debate.

Provenance The floor discussion of Senate Bill 77 begins with the motion to take up the bill and includes multiple distributed amendments; the sponsor later requested the bill be placed on the informal calendar.
