You can bring a gun to another state under federal law, provided you can legally possess it where you start and where you end, and provided you follow the transport rules of every jurisdiction in between. Whether the firearm is “registered” almost never matters. Only a handful of states require any form of firearm registration, and there is no national registry. What controls your trip is how you carry the gun, what kind of firearm it is, and what the laws look like at your destination.
The Federal Safe Passage Rule
The Firearm Owners’ Protection Act, 18 U.S.C. ยง 926A, lets you move a firearm from one place where you legally possess it to another place where you legally possess it, even through states with stricter laws.1Office of the Law Revision Counsel. 18 USC 926A: Interstate Transportation of Firearms
The conditions are rigid. The firearm must be unloaded. Neither the gun nor the ammunition can be readily accessible from the passenger compartment. If your vehicle has a trunk, put everything there. If you drive an SUV, a pickup, or anything else without a separate trunk, the firearm and ammunition go in a locked container, and that container cannot be the glove compartment or the center console.1Office of the Law Revision Counsel. 18 USC 926A: Interstate Transportation of Firearms
Where Federal Protection Runs Out
FOPA is not immunity from arrest. It is an affirmative defense you raise in court. In states with strict handgun laws, officers can and do arrest travelers who are technically covered by the federal statute, and the defense gets sorted out later. That can mean days in jail before a judge weighs in.
FOPA also protects a journey through a state, not a visit to one. A Utah man flying through Newark had his connecting flight canceled, collected his checked bag containing a properly secured handgun, and spent the night at an airport hotel. When he tried to recheck the bag the next morning, he was arrested for illegal handgun possession and for carrying hollow-point ammunition. The Third Circuit held that the overnight stay took him outside FOPA’s protection, because the statute only covers continuous travel.2United States Courts. Revell v. Port Authority of New York and New Jersey, No. 09-2029p>
Brief stops for gas or food are generally fine. Overnight stays, sightseeing, and unplanned layovers are where people get caught. If a canceled flight or a vehicle breakdown forces you to linger, you may find yourself subject to the possession laws of a state where your firearm is a felony to hold.
What to Check at Your Destination
Once you arrive, FOPA drops away and the destination state’s laws take over. Three areas trip up travelers most often.
Magazine Capacity
Many states cap magazine capacity, usually at 10 rounds, sometimes 15. Driving into one of these states with a standard 17-round handgun magazine is a crime the moment you cross the line, even though the magazine was legal where you bought it. Some states restrict only sale or manufacture; others ban possession outright. Check before you go and leave noncompliant magazines behind.
Assault Weapon Bans
Some states ban firearms they classify as assault weapons. The definitions are not consistent. A few states ban specific makes and models by name. Others use a features-based test targeting semi-automatic rifles with combinations of characteristics like pistol grips, adjustable stocks, or threaded barrels. A rifle that is unremarkable in most of the country can be a felony in one of these states.
Ammunition
Ammunition can be illegal on its own. New Jersey, for example, restricts possession of hollow-point ammunition outside the home, with narrow exceptions for hunting and for transport directly to or from a range. In the Newark case, the traveler was charged separately for the hollow points in his luggage.2United States Courts. Revell v. Port Authority of New York and New Jersey, No. 09-2029 Verify your self-defense ammunition is legal at your destination before packing it.
Carrying vs. Transporting
Transporting a locked, unloaded firearm to another state is one question. Carrying it on your person once you arrive is a different one. Whether your concealed carry permit works elsewhere depends on reciprocity between the two states, and the map changes as legislatures update their laws. Official state attorney general or state police websites publish current reciprocity lists, and checking shortly before your trip is more useful than checking a month out.
Even where your permit is recognized, you still follow the host state’s carry rules. Prohibited-location lists vary. Schools, government buildings, courthouses, and bars are common restricted zones, but the details differ. Some states give legal weight to “no firearms” signs on private businesses; others treat those as a request enforceable only through trespass.
Permitless Carry Doesn’t Always Travel
As of 2025, 29 states have adopted some form of permitless carry. Not all of them extend that right to visitors. Some limit permitless carry to residents, so an out-of-state traveler still needs a recognized permit. Verify how the law applies to non-residents before you rely on it. Even if your home state does not require a permit, getting one gives you documentation to present during a stop and unlocks reciprocity agreements that permitless carry alone does not.
If You Get Pulled Over
About a dozen states require you to tell an officer you are carrying a firearm as soon as they identify themselves, without waiting to be asked. These “duty to inform” laws vary in their specifics, but failing to disclose is a separate offense in those states.
Even where the law does not require it, volunteering the information early is the smarter move. Keep your hands visible, tell the officer calmly that there is a firearm in the vehicle and where it is located, and follow their instructions. If the gun is locked in the trunk to satisfy FOPA, say so. That context signals you are a lawful traveler.
Flying With a Firearm
The air-travel rules are uniform and set by TSA, regardless of airline or airport.
Firearms travel in checked baggage only. They are never allowed in the cabin or in a carry-on. At the ticket counter, you must verbally declare that you are checking a firearm.3Transportation Security Administration. Transporting Firearms and Ammunition
The firearm must be unloaded and locked in a hard-sided container. The container has to fully prevent access, and only you should have the key or combination. TSA may ask for the key to inspect the case, but no one else should be able to open it.3Transportation Security Administration. Transporting Firearms and Ammunition
Ammunition must be declared and packed in its original box or a container designed for ammunition. It can go in the same locked case as the firearm. Magazines, loaded or empty, must be securely boxed or enclosed within the hard-sided case. A loose magazine does not count as ammunition packaging unless it completely encloses the rounds.3Transportation Security Administration. Transporting Firearms and Ammunition Airlines add their own restrictions on top of TSA’s, including weight limits on ammunition commonly set around 11 pounds per passenger.4Delta Air Lines. Ammunition, Explosives and Firearms
Checkpoint Mistakes Are Expensive
If TSA finds a firearm in your carry-on at the security checkpoint, the consequences are immediate. Civil penalties reach up to $17,062 per violation. A loaded firearm or one with accessible ammunition typically draws $3,000 to $12,210, plus an automatic criminal referral to local police. Even an unloaded firearm carries a $1,500 to $6,130 range with a criminal referral.5Transportation Security Administration. Civil Enforcement That referral hands you to the laws of whatever state the airport sits in, and in restrictive states those charges can be felonies.
Connecting flights compound the risk. If a cancellation forces you to take possession of your checked bag in a restrictive state, you can end up in exactly the situation the Newark traveler faced. Direct flights are safer when you are traveling armed.
If You Own an NFA Firearm
Short-barreled rifles, short-barreled shotguns, machine guns, destructive devices, and suppressors are regulated under the National Firearms Act, and moving them across state lines requires prior written approval from ATF.6Office of the Law Revision Counsel. 18 U.S. Code 922 – Unlawful Acts The approval comes through ATF Form 5320.20, which you submit before the trip with the firearms, destination, and travel dates. It can go in by mail, fax, or email.7ATF. Application to Transport Interstate or to Temporarily Export Certain National Firearms Act (NFA) Firearms
Skipping this is a federal felony. Conviction carries a fine of up to $10,000, up to 10 years in prison, or both, and the firearm is subject to seizure and forfeiture.8ATF. The National Firearms Act, Title 26, United States Code, Chapter 53 Suppressor owners are the ones most often caught out, because a suppressor that is legal to own at home may be banned outright at the destination.
What a Violation Actually Costs
Knowingly transporting a firearm across state lines with intent to commit a crime carries up to 10 years in federal prison.9Office of the Law Revision Counsel. 18 U.S. Code 924 – Penalties A general willful violation of federal firearms transport rules can bring up to five years. State penalties for possession offenses are often harsher. Unlicensed handgun possession in New York can be charged as a felony carrying years in state prison.
The longer shadow is federal. Anyone convicted of a crime punishable by more than one year of imprisonment is permanently barred from owning, buying, or transporting firearms anywhere in the country.6Office of the Law Revision Counsel. 18 U.S. Code 922 – Unlawful Acts A single mistake on a road trip can mean you never legally touch a firearm again. That is the reason to do the homework before you cross the state line, not after.
