Missouri Files Federal Lawsuit Challenging ATF Suppressor Authority
Missouri Attorney General Catherine Hanaway filed suit against the Bureau of Alcohol, Tobacco, Firearms and Explosives on September 10, 2026, directly challenging the agency's classification and enforcement of sound suppressors under the National Firearms Act. The complaint argues the ATF lacks constitutional authority to regulate suppressors as restricted devices requiring $200 tax stamps, fingerprinting, and months of processing delays. This marks the first state-level legal assault on suppressor restrictions since the Supreme Court's Bruen decision reshaped Second Amendment jurisprudence.
The lawsuit targets the core NFA framework that has governed suppressors for nearly a century. Hanaway's office contends the ATF cannot justify suppressor regulation under post-Bruen scrutiny, which demands historical grounding for any firearm restriction. The agency treats suppressors as weapons requiring federal licensing despite lacking evidence suppressors were commonly regulated at the Founding or in the decades following the Second Amendment's ratification.
Why It Matters for Gun Owners
Current law chains suppressors behind regulatory barriers few other accessories face. A shooter wanting to purchase a suppressor navigates NFA registration, submits fingerprints, pays $200 per unit, waits 6-12 months, and receives a tax stamp for each device. Losing a suppressor means filing theft reports and potentially facing felony charges. Selling one requires identical paperwork and transfer fees. These restrictions effectively price hearing protection out of reach for many shooters.
A Missouri victory forces the ATF to defend suppressor classification under Bruen's demanding historical test. The agency faces a problem: suppressors simply don't have the historical pedigree needed to survive modern constitutional review. They weren't invented until the early 1900s, weren't subject to federal restrictions until the 1930s NFA, and weren't commonly regulated by states before that. Under Bruen, regulations must have "historical analogues" grounded in the Founding era or shortly thereafter. Suppressors fail this test completely.
For competitive shooters, suppressors reduce recoil and muzzle rise—genuine performance advantages in precision rifle matches. For hunters, they decrease hearing damage during long seasons. For homeowners, they lower decibel levels during defensive firearm training. Currently, all these shooters face federal prosecution for possession without proper NFA registration. A successful challenge dismantles this burden entirely.
Background and Legal Strategy
The NFA of 1934 originally targeted machine guns, short-barreled rifles, and suppressors as "gangster weapons." Congress included suppressors without evidence they posed unique public safety threats—the classification reflected Depression-era panic more than genuine danger assessment. Modern courts reviewing the same restrictions apply completely different standards than 1930s lawmakers.
Missouri's lawsuit arrives at the perfect moment. Federal courts have systematically rejected ATF positions on ghost guns, pistol braces, and ammunition regulations over the past three years. Judges increasingly recognize the agency acts beyond its legal authority when it ignores Bruen requirements. The Supreme Court's conservative majority has signaled impatience with regulations lacking historical foundation.
Hanaway's office likely argues suppressors deserve Second Amendment protection as common firearm accessories, not dangerous weapons requiring special federal control. The brief probably cites District of Columbia v. Heller's emphasis on practical utility for lawful purposes. Suppressors reduce hearing damage—a legitimate public health benefit the government theoretically supports.
DownRange Bottom Line
Missouri's AG filed a constitutional challenge the ATF cannot win under current legal standards. The agency lacks historical justification for suppressor restrictions. Federal courts are systematically dismantling ATF regulatory overreach. This lawsuit represents a high-probability path toward eliminating NFA suppressor registration entirely. Gun owners should monitor this case closely—a favorable ruling affects millions of shooters nationwide and establishes precedent for challenging other NFA categories.
