Illinois' 1961 Silencer Ban Faces a Skeptical Seventh Circuit Panel
A three-judge panel of the Seventh Circuit Court of Appeals heard arguments Wednesday on whether Illinois can keep its ban on suppressors. Gun owners challenging the law say it violates the Second Amendment, and the bench pressed their lawyer hard. Peter Patterson, of the Washington firm Cooper & Kirk, argued for the plaintiffs. The challenge began in 2023, when the group sued over the state's prohibition. U.S. District Judge David Dugan upheld the law. The plaintiffs appealed in 2025. The appellate question is narrow: does a ban on a device that muffles a firearm's report survive modern Second Amendment review?
Key Details
The law at issue sits in the Illinois criminal code, enacted in 1961. It makes it a crime to possess any device or attachment used or intended for silencing a firearm's report. The plaintiffs filed suit in 2023, and Judge Dugan rejected their claims at the district level. The case now sits before a three-judge Seventh Circuit panel.
- Court: Seventh Circuit Court of Appeals, three-judge panel
- Argument date: Wednesday, October 28, 2026
- Statute: Illinois criminal code, 1961
- Lower court: U.S. District Judge David Dugan upheld the ban
- Appeal filed: 2025
- Plaintiffs' counsel: Peter Patterson, Cooper & Kirk
- Supreme Court case cited: Wolford v. Lopez, which struck down Hawaii's default ban on carry onto private property open to the public
- Test applied: Bruen (2022), which requires modern firearm rules to fit within historical tradition
Judge John Lee, an Obama appointee, pressed Patterson on where courts should draw the line on what self-defense actually requires. Patterson answered that the only line the court needs to draw covers features that make a functional difference to how the firearm operates. He pointed to the Fifth Circuit's Comeaux decision, which described suppressors as reducing noise, reducing recoil, and improving accuracy.
Background
Bruen replaced the old interest-balancing approach that many circuits used for gun cases. Under that ruling, the government must show that a restriction matches the nation's historical regulatory tradition. Courts now ask whether a modern law has a historical analogue, and judges disagree about how close that analogue must be. Patterson's argument leans on that framework and on the Court's more recent Wolford decision, which applied the same history-and-tradition test to strike down a Hawaii rule.
Suppressors have an unusual federal history. Congress placed them under the National Firearms Act in 1934, which brought them into the registration and tax system. Federal transfer tax on suppressors dropped from $200 to $0 starting January 1, 2026, but buyers still work through NFA paperwork for most transfers. Illinois never followed that federal path. Its ban stands on its own 1961 text, and the state has kept it in place while most of its neighbors permit ownership.
Why It Matters for Gun Owners
Every Illinois resident who owns a suppressor, or wants one, faces felony exposure under the state's statute. That includes owners who bought lawfully in another state and then moved or traveled through Illinois. Gun owners who hunt or shoot along the Illinois border should pay close attention. Indiana, Iowa, Missouri, Kentucky, and Wisconsin all allow suppressor ownership, so a lawful purchase across the line becomes a problem the moment the car crosses back into Illinois.
The ruling also matters beyond Illinois. A Seventh Circuit decision that treats suppressors as arms covered by the Second Amendment would give challengers in other states a strong template. Several states, including California, New Jersey, and New York, maintain their own suppressor restrictions, and every one of those laws would face the same argument. A decision that upholds the ban would strengthen the position that states can restrict accessories without meeting a demanding historical test.
Right now, nothing changes for Illinois owners. The law stands until a court says otherwise. Anyone with a suppressor in Illinois should consult a local attorney before making a move. Anyone traveling should keep suppressors out of Illinois entirely.
DownRange Analysis
The panel's questions tell us more than its closing remarks will. When judges ask counsel to define the exact line for necessary self-defense features, they signal that they want a limiting principle before they strike a state law. That approach fits poorly with Bruen, which asks whether the government can point to historical tradition. Illinois has to produce historical analogues for a ban on a device that Congress regulated only through taxation and registration. A 1961 statute does not supply that history.
Patterson's functional-benefits argument is the right angle. Noise reduction, recoil reduction, and accuracy gains go directly to the mechanics of shooting and hearing protection. A court that refuses to engage with those benefits is not applying Bruen. It is applying a policy preference dressed up as history.
The practical advice is simple. Illinois owners should keep their paperwork clean and avoid transporting suppressors across state lines without legal counsel. Gun owners everywhere should follow the Seventh Circuit docket, because a ruling here will shape the next round of challenges. Donate to the litigation groups already funding these cases, and contact your own state legislators about repealing similar bans before the courts force the issue.
