Federal gun storage laws do very little to tell private owners how to keep firearms at home. There is no federal statute requiring you to use a safe, a trigger lock, or any other device on the guns you own. The federal rules that do exist target licensed dealers at the point of sale, set conditions for transporting firearms across state lines, and govern how guns must be packed for air travel. Everything else about home storage is left to the states.
No Federal Rule Requires You to Lock Up Guns at Home
No federal law tells you to store your firearms in a safe or fit them with a trigger lock inside your own home. That holds true regardless of who else lives there. Even if a minor or a person legally barred from possessing firearms shares your household, federal statutes impose no duty on you to secure your weapons.
The Bipartisan Safer Communities Act, signed in 2022, is sometimes assumed to have changed this. It did not. That law expanded background check procedures, funded mental health programs, and supported state crisis intervention efforts, but it created no national standard for secure firearm storage in private residences. What you actually have to do at home depends on your state, not on Washington.
The Juvenile Handgun Rule Creates an Indirect Duty
Federal law does not tell you how to store a handgun, but it does restrict who may possess one. Under 18 U.S.C. § 922(x), it is illegal to transfer a handgun or handgun-only ammunition to anyone you know or reasonably believe is under 18. It is equally illegal for a juvenile to knowingly possess a handgun or handgun-only ammunition. Violations carry up to one year in prison, rising to up to ten years if the adult had reason to believe the juvenile would use the handgun in a violent crime.1Office of the Law Revision Counsel. 18 USC 922 – Unlawful Acts
This is not a storage law on its face. It never says “lock your handgun in a safe.” But it creates real criminal exposure for adults whose handguns end up in the hands of minors, which makes secure storage a practical necessity in any household with someone under 18. Statutory exceptions allow juvenile handgun possession in narrow circumstances, including hunting, target practice, certain employment and farming activities, military duty, defense against an intruder, and situations covered by written parental consent that the juvenile carries at all times. During transport tied to any of these exceptions, the handgun must be unloaded and kept in a locked container.1Office of the Law Revision Counsel. 18 USC 922 – Unlawful Acts
What Licensed Dealers Must Provide With a Handgun
The clearest federal storage requirement falls on anyone holding a Federal Firearms License. Under 18 U.S.C. § 922(z), every licensed importer, manufacturer, and dealer must provide a secure gun storage or safety device with every handgun transferred to a non-licensee. This obligation was added by the Child Safety Lock Act of 2005.2Bureau of Alcohol, Tobacco, Firearms and Explosives. Open Letter to Federal Firearms Licensees – Child Safety Lock Act of 2005
Federal law defines a qualifying device broadly. It covers external locking devices such as trigger locks and cable locks; built-in mechanisms designed into the firearm that prevent operation without deactivating them; and storage containers like safes, gun cases, or lock boxes opened only by a key, combination, or equivalent method.3Office of the Law Revision Counsel. 18 USC 921 – Definitions
The requirement applies only to handguns. Rifles and shotguns are not covered. Transfers between licensees, transfers to government agencies or law enforcement officers, and transfers of handguns classified as curios or relics are also outside the rule. If a device is temporarily unavailable, the dealer has 10 calendar days after delivering the handgun to get one to the buyer.1Office of the Law Revision Counsel. 18 USC 922 – Unlawful Acts
Dealers who fail to comply face administrative penalties. The ATF may suspend a license for up to six months or revoke it. As an alternative, the ATF may impose a civil penalty of up to $2,500 per violation.4Office of the Law Revision Counsel. 18 USC 924 – Penalties
Civil Immunity When You Actually Use the Device
There is a federal incentive to use the storage device that came with your handgun. Under 18 U.S.C. § 922(z)(3), if you lawfully possess a handgun and store it with a qualifying secure gun storage or safety device, you are immune from civil lawsuits arising out of criminal misuse of that handgun by an unauthorized third party. The protection applies when someone without your permission accessed the handgun and the device rendered it inoperable at the time.1Office of the Law Revision Counsel. 18 USC 922 – Unlawful Acts
The immunity has limits. It does not shield you from claims of negligent entrustment, meaning cases where you knowingly gave access to someone you should have known was dangerous. It also does not cover negligence per se claims. But for the specific scenario of a secured handgun being stolen or accessed without your knowledge and then misused, this provision can block a civil damages suit in both federal and state court.
Transporting Firearms Between States by Car
Interstate transport is one area where federal law does set specific storage rules for private owners. The Firearms Owners’ Protection Act includes a “safe passage” provision at 18 U.S.C. § 926A. If you can lawfully possess a firearm at both the start and end of your trip, no state or local law along the route can penalize you for transporting it, provided you follow the storage requirements.5Office of the Law Revision Counsel. 18 USC 926A – Interstate Transportation of Firearms
Those requirements are strict. The firearm must be unloaded. Neither the firearm nor any ammunition can be readily accessible from the passenger compartment. In a sedan, the trunk satisfies this. In an SUV, hatchback, or pickup with no separate compartment, the firearm and ammunition must go in a locked container. A glove box or center console does not qualify as a locked container, even if it has a lock.6Office of the Law Revision Counsel. 18 USC 926A – Interstate Transportation of Firearms
The protection covers pass-through travel. If you stop in a state where you cannot legally possess the firearm and do anything beyond brief, necessary stops such as refueling, you risk losing the safe-passage defense. Some states have prosecuted travelers aggressively for extended stops, so the letter of the statute matters.
Flying With Firearms
Federal regulations set separate storage rules for air travel. A firearm may go only in checked baggage, never in a carry-on. It must be unloaded and placed in a locked, hard-sided container that completely prevents access. Soft-sided cases and containers that can be pried open do not qualify.7Transportation Security Administration. Transporting Firearms and Ammunition
The TSA’s definition of “loaded” is broader than many owners expect. A firearm is loaded if a live round or any component of a round is in the chamber, cylinder, or an inserted magazine. For civil enforcement, the TSA also treats a firearm as loaded whenever the gun and ammunition are both accessible to the passenger, even if nothing is chambered. Keeping ammunition in a separate locked container, or in factory packaging within the same case, is the safest approach.7Transportation Security Administration. Transporting Firearms and Ammunition
State Law Is Where Home Storage Duties Actually Live
Because federal law leaves home storage alone, states have written their own rules. Some have child access prevention laws that impose criminal liability when a minor obtains an unsecured firearm. Others require all firearms in a home to be locked regardless of who lives there. Penalties range from misdemeanor charges to felony liability when a child is injured or killed.
Federal law does not preempt these state rules, and many states have gone well beyond it. If you own firearms, the storage obligations that actually affect your day-to-day life almost certainly come from your state code. Checking your state’s child access prevention and secure storage statutes is the next step after understanding the federal baseline.
