California gun laws apply to out-of-state visitors the moment you cross the state line, and they don’t care what’s legal back home. Your firearm must be unloaded in the vehicle, handguns must be locked in the trunk or a locked container, certain guns and any magazine holding more than 10 rounds can’t come with you at all, and your home-state concealed carry permit has no effect here. If you’re moving to California rather than visiting, you have 60 days to report every firearm you brought with you.
How to Transport a Firearm in Your Vehicle
Every firearm in a vehicle in California must be unloaded. Under state law, a gun counts as loaded when a live round is in the chamber, in an attached magazine, or physically connected to the firearm in any way.1California Legislative Information. California Penal Code 16840 A handgun with an empty chamber but a loaded magazine inserted is still loaded for legal purposes. Remove the magazine and keep it detached.
Handguns carry an extra rule. They must be stored in the vehicle’s trunk or in a locked container, meaning a fully enclosed case secured by a padlock, key lock, combination lock, or similar device. A glove compartment or center console doesn’t count, even if it locks.2State of California – Department of Justice – Office of the Attorney General. Transporting Firearms in California
Rifles and shotguns must be unloaded during transport but don’t require a locked container in most circumstances.2State of California – Department of Justice – Office of the Attorney General. Transporting Firearms in California
One misconception worth clearing up: California does not require ammunition to be stored somewhere separate from the firearm. The rule is only that no ammunition can be in or attached to the gun. Ammo can ride in the same vehicle, even in the same case, as long as none of it is loaded into or connected to the firearm.
Passing Through California Without Stopping
If you’re driving through California to somewhere else, federal law provides a limited shield. The federal Peaceable Journey statute lets you transport a firearm through any state if you can legally possess it at both your origin and destination, the gun is unloaded, and neither the firearm nor the ammunition is readily accessible from the passenger compartment. If your vehicle has no separate trunk, both must be in a locked container other than the glove compartment or console.3Office of the Law Revision Counsel. 18 USC 926A – Interstate Transportation of Firearms
In practice, California law enforcement reads this protection narrowly. Stop for anything beyond brief fuel or food breaks, and you may be treated as present in the state rather than passing through. The safe approach is to comply with federal and California rules simultaneously: handguns unloaded and locked in the trunk, all firearms unloaded, no ammunition attached to any of them.
Firearms and Magazines You Cannot Bring
California bans entire categories of firearms that are legal in most other states. Bringing one across the border can result in felony charges carrying four to eight years in prison.4California Legislative Information. California Penal Code 30600
Assault Weapons
California defines assault weapons by features, not brand names. A semiautomatic centerfire rifle without a fixed magazine qualifies if it has any one of several features, including a pistol grip protruding below the action, a thumbhole stock, a folding or telescoping stock, a grenade or flare launcher, a flash suppressor, or a forward pistol grip. A semiautomatic centerfire rifle with a fixed magazine over 10 rounds, or an overall length under 30 inches, also qualifies. Similar tests apply to semiautomatic pistols and shotguns.5California Legislative Information. California Penal Code 30515
The registration windows for assault weapons closed years ago, and there is no current path for a new owner to register one.6State of California Department of Justice. Frequently Asked Questions – Assault Weapons and .50 BMG If your firearm falls into this category, it cannot legally enter California.
.50 BMG Rifles
California also prohibits .50 BMG rifles, defined as centerfire rifles capable of firing a .50 BMG cartridge. A person moving to California who already owns one can potentially bring it, but only after obtaining a permit from the Department of Justice before the rifle crosses the state line.7Justia Law. California Penal Code 30900-30965 – Registration of Assault Weapons and .50 BMG Rifles Importing one without that permit is a felony.4California Legislative Information. California Penal Code 30600
Magazines Over 10 Rounds
Any feeding device holding more than 10 rounds is illegal to possess, import, or buy in California. That applies to magazines for both handguns and rifles. Possession is a misdemeanor or infraction depending on the circumstances, and importing one can bring up to a year in county jail or a state prison sentence.8California Legislative Information. California Penal Code 32310 Leave any magazine holding more than 10 rounds at home or in another state before entering California. There are no exceptions for travelers or new residents.
Ammunition Rules Differ by Status
California treats ammunition differently for visitors and residents. Non-residents cannot buy ammunition inside California, because the state’s background check system requires a valid California driver’s license or ID card. But non-residents can bring their own ammunition into the state for personal use, without a background check or a vendor.
If you’ve moved here, the rules flip. Residents cannot simply buy ammunition out of state and bring it back. It has to be shipped to a licensed California ammunition vendor, who processes the transfer after a background check.9California Legislative Information. California Penal Code 30314 Buying in-state runs through a point-of-sale check as well. If you already have a firearm registered in California’s system, the standard check is about $1. If you don’t, expect $19 for a more thorough one.
Your Concealed Carry Permit Does Not Transfer
California does not honor concealed carry permits from any other state. A CCW license from Texas, Arizona, Florida, or anywhere else has zero legal effect in California.10State of California – Department of Justice – Office of the Attorney General. Regulations – Uniform Carry Concealed Weapons Licenses
Carrying a concealed handgun without a California-issued CCW is a criminal offense. For a first-time offender with no aggravating factors, it’s a misdemeanor punishable by up to a year in county jail, a fine of up to $1,000, or both. It becomes a felony if the gun is loaded and unregistered, if the person has prior felony convictions, or if other aggravating circumstances exist.11California Legislative Information. California Penal Code 25400
Open carry isn’t a workaround. California prohibits open carry of firearms in most public places, loaded or unloaded. Visitors who assume they can openly carry a holstered handgun because they lack a concealed permit are making a serious legal mistake.
Getting a California CCW as a non-resident is extremely difficult. State law directs applicants to the sheriff of the county where they reside, or the county where they maintain a principal place of employment or business and spend substantial time there. A visitor with no California residence or employment has no clear statutory path to apply.
If You Are Moving to California
Anyone who moves to California with firearms is classified as a “personal firearm importer” and must report every firearm brought into the state within 60 days of establishing residency.12State of California – Department of Justice – Office of the Attorney General. Firearms Information for New California Residents California determines residency the same way it does for driver’s licenses. Renting an apartment, starting a job, or enrolling children in school can start the clock.13California Legislative Information. California Penal Code 17000 For military members, residency begins on discharge from active service in the state.
The report is a New Resident Report of Firearm Ownership submitted to the California Department of Justice. It asks for the make, model, caliber, and serial number of each firearm, along with a $19 processing fee paid by check or money order.14California Department of Justice. New Resident Report of Firearm Ownership Incomplete forms are returned unprocessed, which can eat into the 60-day window quickly.
Missing the deadline is a criminal offense. For handguns and centerfire semiautomatic rifles, the penalty can reach up to a year in county jail, a state prison sentence, a fine of up to $1,000, or both.15California Legislative Information. California Penal Code 27590 For other firearms, it’s a misdemeanor. The reporting process covers only the firearms you already own; buying a new firearm after you’ve moved runs through a licensed dealer, including a 10-day waiting period.16State of California – Department of Justice – Office of the Attorney General. California Department of Justice Firearms Frequently Asked Questions
New residents also have alternatives to reporting. You can sell or transfer your firearm to a California licensed dealer or, through a licensed dealer, to another person, or you can surrender it to a California police or sheriff’s department.12State of California – Department of Justice – Office of the Attorney General. Firearms Information for New California Residents
Off-Roster Handguns and the New-Resident Exemption
California maintains a Roster of Handguns Certified for Sale, and licensed dealers can only sell listed models to the general public.17California Department of Justice – Office of the Attorney General. Handguns Certified for Sale New residents get an important exemption. When you file your New Resident Report, you can register handguns that are not on the roster, as long as they’re otherwise legal to possess in California. You keep what you legally owned in your previous state, even models that California dealers cannot sell.
Once those off-roster handguns are registered in California, you can transfer them to other private parties through a licensed dealer, because private party transfers are exempt from the roster requirement.17California Department of Justice – Office of the Attorney General. Handguns Certified for Sale The transfer still runs through a licensed dealer with a background check and a 10-day waiting period, but the roster itself doesn’t block the sale.
