Suppressors are not legal for civilians in Delaware. State law classifies firearm silencers as “destructive weapons” under Title 11, Section 1444 of the Delaware Code, grouping them with bombs, sawed-off shotguns, and machine guns. Possessing one is a Class E felony that carries up to five years in prison.1FindLaw. Delaware Code Title 11 1444 – Possessing a Destructive Weapon Federal compliance does not override the state ban, and there is no permit, license, or registration process that makes civilian ownership legal.
What the Ban Covers
Section 1444 makes it illegal to make, sell, buy, receive, or possess a firearm silencer. Every stage of ownership is covered, so you cannot legally acquire a suppressor through any channel in Delaware, and simply having one is enough to support a felony charge.1FindLaw.

Hunters, sport shooters, and competitive marksmen have no carve-out. Full compliance with the National Firearms Act, including a registered suppressor and an approved ATF tax stamp, does nothing to shield you from state prosecution. Delaware’s prohibition runs independently of federal law.
Who Can Legally Possess a Suppressor
The statute recognizes three narrow exceptions, none of which reach ordinary civilians:
- Members of the armed forces acting in an official capacity.
- Police officers in Delaware who are authorized to carry these weapons.
- State and federal wildlife biologists certified by an accredited state enforcement agency, and only for wildlife disease control or population management.
The wildlife biologist exception is tied to a specific professional purpose. A certified biologist who kept a suppressor for personal recreational use would fall outside the exception.1FindLaw. Delaware Code Title 11 1444 – Possessing a Destructive Weapon
Penalties if You Are Caught
A Class E felony in Delaware carries up to five years of incarceration. There is no mandatory minimum, so a judge has discretion to impose a shorter sentence or suspend prison time in favor of probation. Any portion of the sentence actually served in prison is not eligible for parole.2Justia Law. Delaware Code Title 11 4205 – Sentence for Felonies
Judges may add a fine on top of incarceration, and Delaware gives the court broad discretion to set that amount for a felony conviction.2Justia Law. Delaware Code Title 11 4205 – Sentence for Felonies Expect to lose the suppressor itself, and potentially the firearm it was attached to. Delaware law enforcement has authority to seize and dispose of weapons connected to a criminal case, including transferring them to a federally licensed dealer or destroying them.3Justia Law.

Federal Charges Can Stack
A suppressor that violates Delaware law can also violate federal law if it is unregistered under the National Firearms Act. Under 26 U.S.C. § 5871, possession of an unregistered silencer is punishable by up to ten years in federal prison and a fine of up to $10,000.4Office of the Law Revision Counsel. 26 USC 5871 – Penalties
Most suppressor cases in ban states are prosecuted at the state level, but federal charges become more likely when a case involves interstate trafficking, organized crime, or other aggravating factors. Dual sovereignty allows separate state and federal prosecutions for the same conduct, so a defendant can theoretically face both.
Driving Through Delaware With a Suppressor
This is where owners from Pennsylvania, Maryland, and Virginia most often get caught off guard. If you legally own a suppressor in one of those states and drive through Delaware, you are carrying a Class E felony in your vehicle the moment you cross the state line.
Federal law offers a “peaceable journey” protection under 18 U.S.C. § 926A. You may transport a firearm through a state where it would otherwise be illegal if you can lawfully possess it at both your origin and destination, the firearm is unloaded, and it is not readily accessible during transport.5Office of the Law Revision Counsel. 18 USC 926A – Interstate Transportation of Firearms
On paper, that should cover a locked, cased suppressor in the trunk of a car driving from Pennsylvania to Virginia. In practice, relying on it with NFA items is risky. State and local officers may not recognize or respect the federal safe-passage provision at a traffic stop, and asserting it as a defense at trial is a far worse outcome than routing around Delaware. If you must pass through, keep the suppressor unloaded, locked in a hard case, and stored where the driver cannot access it. The safer choice is to plan a route that avoids the state.
Moving to Delaware With a Suppressor You Already Own
Relocating creates an immediate problem. The moment you establish residency, you are in possession of a destructive weapon under state law. There is no grace period, no grandfather clause, and no process for registering or legalizing a suppressor you lawfully owned in another state.
Before the move, transfer the suppressor to someone in a state where ownership is legal, store it with a trusted person outside Delaware, or transfer it to a federally licensed dealer. All NFA transfers go through the ATF’s registration process, so start well before your move date. Bringing the suppressor into Delaware “temporarily” while you sort out the transfer is still illegal possession.
Why the 2026 Tax Stamp Change Does Not Help
On January 1, 2026, the federal tax stamp fee for NFA items dropped from $200 to $0. The registration process itself is unchanged, but the financial barrier is gone in states where suppressors are legal.
For Delaware residents, this changes nothing. Even with a $0 federal tax stamp and a fully approved ATF registration, state law still prohibits possession. The destructive weapon classification applies regardless of federal paperwork, and prosecutors do not need to show you failed any federal step to charge you under Section 1444.
