Thinking about buying a suppressor in Hawaii? Stop right there. This one law trips up more people than you’d think.
Hawaii has some of the strictest gun laws in the country. And when it comes to suppressors, the rules are simple. They’re banned. No exceptions, no permits, no workarounds. Let’s break down exactly what that means for you.
What Is a Suppressor?
A suppressor is a device that attaches to the end of a gun barrel. It reduces the loud bang a gun makes when it’s fired. Some people call them silencers, but that’s actually a bit misleading.
Suppressors don’t make guns silent. They just make them quieter. Think of it like a muffler on a car. It doesn’t stop the engine noise completely, it just brings the volume down.
People use suppressors for a few reasons. Hearing protection is a big one. Reducing noise for neighbors during target practice is another. Sound reasonable, right? Well, Hawaii doesn’t see it that way.
Basic Suppressor Laws in Hawaii
The Complete Ban
Here’s the deal. Hawaii Revised Statutes Section 134-7 makes it illegal to own, sell, or transfer a firearm suppressor. This law applies to everyone. It doesn’t matter if you’re a hunter, a target shooter, or a collector.
Wondering if there’s some special permit that gets around this? Nope. Unlike some restricted items, there’s no license or application process for suppressors in Hawaii. The answer is always no.
This is different from most of the country. In 42 states, suppressors are legal if you go through the federal process. Hawaii is one of just a handful of states that says no entirely, along with California, New York, New Jersey, Massachusetts, Illinois, Delaware, and Rhode Island.
Federal Approval Doesn’t Matter Here
Stay with me here, because this part confuses a lot of people. Under federal law, suppressors are regulated by the National Firearms Act. You can apply through the ATF, the federal agency that oversees firearms. You pay a tax, pass a background check, and get approved.
Sound complicated? It’s actually not that bad on the federal side. In fact, big news dropped in 2026. The federal $200 tax on suppressors was eliminated entirely. That tax had been in place since 1934.
But here’s the catch. None of that matters in Hawaii. Even if the ATF approves you and you have a valid federal tax stamp, Hawaii state law still says no. State law wins here. Federal approval means literally nothing once you’re on Hawaii soil.
Why Does Hawaii Ban Suppressors?
Honestly, this is the part most people miss. Hawaii lawmakers have long argued that suppressors make gun crimes harder to detect. A gunshot without the loud bang is harder for neighbors or police to notice.
Supporters of suppressors disagree. They say suppressors protect hearing and reduce noise pollution near ranges. This is a real debate happening across the country right now.
But in Hawaii, that debate hasn’t changed the law. Some state lawmakers have floated the idea of loosening suppressor rules. As of now, nothing has passed. The ban stands exactly as it has for decades.
Penalties and Consequences
Okay, this part is important. Read it carefully.
Possessing a suppressor in Hawaii is charged as a Class B felony. That’s not a minor citation. A Class B felony is serious business, similar to charges for burglary or certain drug crimes.
If convicted, you could face up to 10 years in prison. You could also face steep fines on top of that. This isn’t a slap on the wrist. It’s a conviction that can follow you for life.
Think of it like the difference between a speeding ticket and a DUI. A speeding ticket is annoying but temporary. A felony conviction changes your job prospects, your voting rights in some cases, and your ability to own any firearm again. That’s the level we’re talking about here.
Selling or transferring a suppressor to someone else carries the same felony-level consequences. It doesn’t matter if money changed hands or if you just gave it to a friend. The law treats it the same way.
Special Circumstances
You might be wondering about exceptions. Law enforcement officers and military personnel using suppressors in an official capacity are handled differently under separate legal provisions. That’s standard across most states.
For everyday civilians though? There are no known exceptions. Not for hunting. Not for target practice. Not for collectors who just want one for display. None of it matters.
A friend of mine looked into this a while back. He figured his federal paperwork would count for something in Hawaii. Turns out, it didn’t. He found out the hard way that state law is the final word here.
Don’t be that person. If you’re moving to Hawaii from a state where suppressors are legal, you cannot bring one with you. You’d need to sell it, transfer it out of state, or leave it behind before relocating.
Traveling With a Suppressor
Here’s where it gets interesting. If you legally own a suppressor somewhere else, like Texas or Florida, you generally don’t need federal approval just to drive it through other states. Most states don’t require notification for suppressors crossing their borders.
But Hawaii is an island. Getting there means flying or shipping items, not driving. And Hawaii’s ban means you legally cannot bring a suppressor into the state at all, even temporarily.
This trips up hunters and shooters visiting from the mainland more than you’d expect. Always check the current rules before you pack anything firearm-related for a Hawaii trip. When in doubt, leave it at home.
What About Short-Barreled Rifles and Other NFA Items?
Suppressors aren’t the only restricted item in Hawaii. Short-barreled rifles, sometimes called SBRs, are also prohibited for civilian ownership. Same goes for short-barreled shotguns.
Basically, Hawaii takes a hard line against most items regulated under the National Firearms Act. If you’re used to gun laws in a more permissive state, Hawaii is going to feel like a totally different world.
Personally, I think this is one of those areas where doing your research before you move or travel really pays off. Gun laws vary wildly state to state, and assuming your home state’s rules apply elsewhere is a mistake people make constantly.
How to Stay Compliant
So what should you actually do with this information? First, if you own a suppressor and you’re moving to Hawaii, get rid of it before you arrive. Sell it, transfer it legally to someone in a state where it’s allowed, or store it with a trusted person outside Hawaii.
Second, don’t try to bring one for a visit. It’s not worth the risk. A felony charge over a quiet trip to the range isn’t a trade anyone should make.
Third, if you’re unsure about any part of this, talk to a licensed attorney in Hawaii. Gun laws are detailed, and specific situations can get complicated fast. A quick consultation is way cheaper than a felony defense.
Finally, keep an eye on state legislation. Laws around suppressors have shifted in other states recently, and Hawaii lawmakers do periodically revisit firearm policy. What’s true today might not be true in a few years.
Reporting Violations
If you believe someone is illegally possessing or selling a suppressor in Hawaii, you can report it to local police or the Honolulu Police Department’s firearms unit. You can also contact the ATF, since federal registration violations may apply too.
Most people don’t realize how seriously law enforcement treats these reports. Given the felony status, tips about suppressor violations are typically taken seriously and investigated.
Frequently Asked Questions
Are suppressors illegal in Hawaii?
Yes. Hawaii bans civilian possession, sale, and transfer of firearm suppressors under state law, with no exceptions.
Can I use my federal ATF approval to own a suppressor in Hawaii?
No. Federal approval through the ATF does not override Hawaii’s state ban. State law controls, and possession remains illegal regardless of federal paperwork.
What happens if I’m caught with a suppressor in Hawaii?

Can I bring my suppressor with me while visiting Hawaii?
No. Even temporary possession during travel is illegal. Leave it at home before your trip.

No. The elimination of the federal $200 tax only affects the federal process. Hawaii’s state ban remains completely unchanged.
Final Thoughts
Hawaii’s suppressor ban is about as strict as it gets. No permits, no workarounds, no exceptions for civilians. A felony conviction with up to 10 years in prison is a heavy price for a device that’s legal almost everywhere else in the country.
Now you know the basics. Stay informed, stay compliant, and if you’re ever unsure, talk to a licensed attorney before making any decisions involving suppressors in Hawaii.
