Most people assume suppressors are just a federal issue. They’re not. Maryland has its own rules. And they are strict.
If you live in Maryland and own a firearm, you need to read this. The penalties can be serious, and ignorance is not a defense in court.
What Is a Suppressor?
A suppressor is a device attached to a firearm. It reduces the sound of a gunshot. You may also hear it called a “silencer.” Both words mean the same thing.
Suppressors do not make guns silent. That is mostly a movie myth. They do reduce noise. But they are still heavily regulated across the country.
Makes sense, right? Loud gunfire is one of the ways law enforcement identifies dangerous situations. So the government keeps a close eye on anything that changes that.
Are Suppressors Legal in Maryland?
Okay, this is the part most people get wrong.
Suppressors are illegal in Maryland. Full stop. The state bans civilians from owning, making, selling, or transferring suppressors. This is stricter than federal law.
Under federal law, you can own a suppressor. You just have to register it, pay a $200 tax, and pass a background check. That process goes through the National Firearms Act, or NFA.
But Maryland does not follow that path. The state goes further. Even if you have federal NFA approval, owning a suppressor in Maryland is still a crime.
You’re not alone if this surprises you. A lot of gun owners in other states assume NFA approval works everywhere. In Maryland, it does not.
Maryland’s Suppressor Ban: The Basics
Maryland law bans several types of devices related to suppressors. Let us break them down.
What Exactly Is Banned?
Maryland prohibits owning, making, transferring, or using a silencer or suppressor. The ban applies to devices for any firearm. It does not matter if the gun itself is legal.
The law also covers homemade devices. You cannot build a suppressor yourself and claim it is legal. Any device that reduces firearm sound is covered under this ban.
Wondering if partially built suppressors count? Yes, they do. Solvent trap kits and certain accessories can also fall under scrutiny if they are clearly intended to become suppressors.
Who Does the Ban Apply To?
The ban applies to regular civilians in Maryland. That means you, me, and most people reading this article.
There are some narrow exceptions. We will cover those below. But for the average gun owner, the answer is simple: suppressors are off-limits in Maryland.
Penalties for Owning a Suppressor in Maryland
Here is where things get serious.
Possessing a silencer in Maryland is a felony. Not a misdemeanor. A felony.
If convicted, you could face up to three years in prison. You could also face significant fines. A felony conviction can also strip you of your right to own any firearm going forward.
Think about that for a second. One illegal suppressor could cost you your gun rights permanently. That is a huge consequence.
Honestly, this is one of those laws where the penalty surprises people. Most folks think it would be a small fine. It is not.
Manufacturing or Selling Suppressors
It gets worse if you are making or selling them.
Manufacturing a suppressor in Maryland carries even heavier penalties. Selling or transferring one does too. If you are caught distributing suppressors, you are looking at serious felony charges.
Hold on, this part is important. Even gifting a suppressor to someone is illegal. You do not have to sell it to break the law. Transferring ownership in any way is prohibited.
This applies to online sales too. If you buy a suppressor online and have it shipped to Maryland, that is still illegal. The destination matters, not just where the sale happens.
What About Suppressors Bought in Other States?
A lot of people ask this one. I get it. It seems like it should work differently.
Here is the reality. If you legally buy a suppressor in another state and bring it to Maryland, you are breaking Maryland law. The suppressor does not become legal just because it was purchased elsewhere.
This is similar to how some states ban certain magazines or weapons that are legal in neighboring states. Crossing the state line does not clear you legally.
Many people find out the hard way. Do not be one of them.
Are There Any Exceptions?
Yes, there are a few narrow ones. But they are limited.
Law enforcement officers may be authorized to use suppressors in certain situations. This typically applies to on-duty use by authorized agencies. Even officers generally cannot own suppressors personally for off-duty use.
Licensed dealers who are federally authorized may handle suppressors for the purpose of transfer to law enforcement. But this is a very specific and narrow exception. Regular gun dealers cannot simply stock suppressors for civilian sale in Maryland.
Military personnel may also have exceptions that apply during official duties. But personal ownership is still restricted.
If you think you might qualify for an exception, talk to a licensed attorney. Do not assume you qualify without legal guidance.
Federal Law vs. Maryland Law
This comparison trips people up a lot.
At the federal level, the NFA allows suppressor ownership. You apply, pay the $200 tax, wait for approval, and then legally possess the suppressor under federal law.
Maryland does not recognize this process for civilian ownership. The state has the right to be stricter than federal law. And it is.
Think of it like a traffic law. A federal highway might allow 70 mph. But a state can lower the limit on its own roads. Maryland lowered the limit here to zero.
So even if the ATF gives you the green light federally, Maryland says no.
Recent Updates and Changes
As of 2026, Maryland has not loosened its suppressor laws. In fact, the political climate in Maryland continues to favor stricter gun regulations.
There have been national conversations about reforming the NFA or even removing suppressors from the NFA list entirely. Some states have moved toward easier suppressor ownership. Maryland has not followed that trend.
Personally, I think it is worth keeping an eye on any new legislation each year. Laws can change. Always check for updates if you are a gun owner in Maryland.
What You Should Do If You Already Own One
Okay, pause. Read this carefully.
If you moved to Maryland from another state and brought a suppressor with you, you may already be in violation of the law. This is a serious situation.
Do not try to figure this out on your own. Contact a licensed firearms attorney in Maryland immediately. They can advise you on how to legally handle the situation. Options may include transferring the suppressor out of state or surrendering it.
Do not attempt to sell it, give it away, or store it somewhere and hope for the best. Any of those actions could make your legal situation worse.
How to Stay on the Right Side of the Law
Pretty straightforward once you know the rules.
If you are a Maryland resident, do not purchase, own, make, or transfer a suppressor. That is the simplest path to staying legal.
If you are interested in hearing protection while shooting, Maryland law still allows electronic ear protection and traditional ear muffs. These are legal and widely available.
If you travel to other states to shoot, know the laws in those states as well. Suppressors may be legal there. But when you come home to Maryland, leave them behind.
And if you are ever unsure about a specific device or accessory, ask a licensed firearms attorney. It is always better to ask before you act.
