Fifth Circuit Rules Silencers Are Protected Second Amendment Arms

The United States Court of Appeals for the Fifth Circuit just issued a landmark Second Amendment decision in United States v. Comeaux, becoming the first federal court of appeals to definitively hold that silencers are “Arms” protected by the Second Amendment.

That is a major step forward for suppressor rights.

For years, courts have recognized the practical benefits of silencers while still denying them Second Amendment protection. Some courts have treated silencers as mere accessories. Others have argued that because a silencer is not strictly necessary for a firearm to function, it falls outside the protection of the Second Amendment.

That reasoning creates a serious problem. If only the bare parts required to fire a gun are protected, then other critical firearm components, like sights, optics, magazines, and similar tools, could also be pushed outside the Second Amendment.

In Comeaux, the Fifth Circuit focused on the better question:

Does a silencer facilitate lawful armed conduct, including self-defense?

The court answered yes.

That approach follows the standard set by the U.S. Supreme Court. It recognizes that the Second Amendment protects the practical ability to keep and bear arms for lawful purposes, including self-defense. It does not protect only the bare mechanical operation of a firearm.

Just as importantly, this standard focuses on constitutionally protected conduct rather than only the physical characteristics of the item. People have constitutional rights. Items are protected when they help people exercise those rights.

The Fifth Circuit’s prior opinion in Peterson left open the question of whether silencers are Second Amendment “Arms.”

In Comeaux, the court answered that question directly:

“They are.”

That short sentence makes this a momentous opinion.

The court explained that silencers provide “reduced loudness (and reduced risk of hearing loss), lower recoil from the firearm, elimination of muzzle blast, increased accuracy, and faster follow-up shots.”

The court then explained why those benefits matter under the Second Amendment:

“Those are all critical functions that make firearms both safer and more effective for their core lawful purpose of self-defense.”

That is the core of the decision.

The Fifth Circuit recognized that suppressors are not just accessories with no constitutional significance. They help make firearms safer and more effective for lawful use. Because of that, silencers fall within the Second Amendment’s protection.

The court could have gone even further.

Consider a common home-defense scenario involving a nighttime break-in. A silencer can be kept attached to a home-defense firearm, meaning there is no need to fumble for earmuffs in the dark. It can help a person communicate with family members, listen for critical sounds, and avoid having their senses dulled by hearing protection at the moment they may need those senses most.

A suppressor also helps protect the hearing of the person using the firearm and the family members nearby. In the event shots are fired indoors, the ability to see, hear, and communicate after the first shot could be critical.

Those are not incidental benefits. They are directly connected to the lawful exercise of the right to keep and bear arms.

The Comeaux decision is a major step forward, but it is not a complete victory.

The Fifth Circuit still upheld the National Firearms Act in this case. That part of the opinion is deeply disappointing. The NFA continues to burden the right to keep and bear arms by requiring registration and federal permission before possessing a protected item.

It would be easy to view the Comeaux opinion as a failure because the NFA was ultimately upheld.

But that misses the importance of what the court did decide.

The NFA’s validity is still very much in question. Multiple lawsuits, including one filed by Silencer Shop Foundation, are challenging the NFA on other constitutional grounds in addition to Second Amendment arguments.

Securing Second Amendment protection for silencers is a necessary first step. It matters for the broader fight against the NFA. It matters for challenges to state laws that restrict or ban silencer ownership. And it will be fundamentally important if a future Congress attempts to ban suppressors nationwide.

The Fifth Circuit’s holding changes the legal landscape.

Suppressors can no longer be dismissed as unprotected accessories. The decision gets past the first step of the Bruen analysis and, at least in the Fifth Circuit, shifts the burden to the government to show that its restrictions are consistent with the nation’s historical tradition of firearm regulation.

That makes Comeaux a critical doctrinal advance.

The court crossed the threshold question and held that silencers are protected “Arms.”

The Comeaux opinion also creates the kind of circuit split that could bring the Second Amendment protection question before the U.S. Supreme Court.

Before this decision, federal courts had generally either avoided the question or held that silencers were not protected bearable arms under the Second Amendment.

Comeaux turns that tide.

The Fifth Circuit provided substantial analysis and rejected the theories other courts have used to deny Second Amendment protection to silencers. Rather than asking whether a silencer is absolutely necessary for a firearm to function, the court asked whether it facilitates lawful armed conduct.

That is the right question.

The court’s reasoning is rooted in Supreme Court precedent and correctly focuses on conduct and the practical exercise of the right to keep and bear arms.

The Supreme Court has repeatedly made clear that the Second Amendment is not a second-class right. The Fifth Circuit’s decision in Comeaux applies that principle to suppressors.

One of Silencer Shop Foundation’s core purposes is to achieve Second Amendment protection for silencers. The Fifth Circuit’s decision is a huge step forward in that endeavor.

For too long, suppressors have been burdened by outdated laws, misinformation, and judicial opinions that failed to understand their practical role.

Suppressors are safety tools. They help reduce hearing damage. They improve control. They reduce muzzle blast. They can make firearms safer and more effective for lawful defensive, sporting, hunting, and training purposes.

The Fifth Circuit recognized those realities and connected them to the constitutional text.

That is exactly the kind of progress Silencer Shop Foundation exists to support.

Comeaux does not end the fight. The Fifth Circuit still upheld the validity of the NFA based on existing circuit precedent in Peterson. But the decision moves the law decisively in the right direction by confirming that silencers are protected “Arms” under the Second Amendment.

Silencer Shop Foundation is currently leading a case in Texas federal court challenging the NFA under the Second Amendment and under the theory that Congress lacked authority to enact the NFA in the first place.

United States v. Comeaux is not the final word on suppressor rights, the NFA, or state-level silencer bans.

But it is a landmark Second Amendment decision.

For the first time, a federal court of appeals has definitively held that silencers are protected “Arms.” That matters for suppressor owners, future NFA challenges, state-law challenges, and any future attempt to ban suppressors.

The fight continues, but the law just moved in the right direction.
