Shotguns are legal to own in California, but the state regulates almost every part of the process: who can buy one, which models and configurations are allowed, how the sale happens, and how the gun is stored, transported, and eventually transferred. If you can pass a background check, meet the age rules, and stick to legal configurations, you can own a shotgun. Break the rules and you’re looking at anything from a misdemeanor to years in state prison.
Who Is Barred From Owning a Shotgun
Some people cannot legally possess any firearm in California, shotguns included. Under Penal Code 29800, a felony conviction is a permanent bar. Two or more convictions for brandishing a firearm carry the same lifetime prohibition, and so does an outstanding warrant for certain offenses if you know the warrant exists.1California Legislative Information. California Penal Code 29800 – Person Convicted of Specified Offense Addiction to any narcotic drug also disqualifies you.
Mental health findings can trigger a prohibition too. A court finding that you’re a danger to others because of a mental disorder, or that you’re incompetent to stand trial, blocks purchase and possession unless a court later clears you.2California Department of Justice. Firearms Prohibiting Categories Federal law layers on additional bars, including for anyone dishonorably discharged from the military or convicted of a domestic violence misdemeanor.
Beyond those categorical bars, California allows Gun Violence Restraining Orders. Family members, household members, coworkers, and law enforcement can ask a court to temporarily remove firearms from someone who poses a significant risk to themselves or others. These orders can last anywhere from 21 days to five years.
Age Rules for Buying a Shotgun
Penal Code 27510 generally bars licensed dealers from selling any firearm to someone under 21. Shotguns are one of the few exceptions. If you’re at least 18, a dealer can sell you a shotgun when you fit one of these categories:3California Legislative Information. California Penal Code 27510
- You hold a valid, unexpired hunting license from the California Department of Fish and Wildlife.
- You’re currently serving in the U.S. Armed Forces, National Guard, Air National Guard, or an active reserve component.
- You’re an honorably discharged veteran and can document your discharge.
- You’re an active peace officer or federal agent authorized to carry a firearm on duty.
Under 18, no dealer can sell, loan, or transfer any firearm to you. If you’re 18 to 20 and none of the exemptions apply, you wait until your 21st birthday.
How a Shotgun Purchase Works
Every shotgun sale in California runs through a licensed firearms dealer, including private sales between two individuals. The dealer submits a Dealer’s Record of Sale to the California Department of Justice, which checks state and federal databases.4State of California – Department of Justice – Office of the Attorney General. Ammunition Purchase Authorization Program Frequently Asked Questions Even if the check clears the same day, you still wait a full 10 days before you can take the gun home.
You also need a Firearm Safety Certificate before the sale closes. You earn one by passing a written test on firearm laws and safe handling, given by a licensed dealer. The test fee is $25. The dealer verifies the certificate before finalizing the paperwork.
On top of the sticker price, California adds an 11% state excise tax on retail firearm and ammunition sales under Assembly Bill 28, which took effect in July 2024. That’s on top of regular sales tax and any dealer processing fee.
Which Shotguns Are Illegal in California
Some shotgun designs are banned outright. Penal Code 30515 classifies a shotgun as an assault weapon, and therefore illegal to possess, sell, or transfer, if it matches any of these descriptions:5California Legislative Information. California Penal Code 30515 – Assault Weapons
- A semiautomatic shotgun with a folding or telescoping stock combined with a conspicuous pistol grip, a thumbhole stock, or a vertical handgrip.
- A semiautomatic shotgun that accepts a detachable magazine.
- Any shotgun, regardless of action, with a revolving cylinder.
People who registered an assault-weapon-classified shotgun before the ban can keep it under that registration, but they cannot sell or transfer it inside California.
Short-Barreled Shotguns
Penal Code 33215 prohibits shotguns with a barrel under 18 inches or an overall length under 26 inches. Federal law lets you register short-barreled shotguns under the National Firearms Act; California offers no equivalent path. The offense is a wobbler: a misdemeanor carries up to one year in county jail, and a felony carries up to three years in state prison.6California Legislative Information. California Penal Code 33215
Modifications That Turn a Legal Shotgun Illegal
Small changes can move a shotgun into prohibited territory. Adding a detachable magazine to certain semiautomatics reclassifies them as assault weapons. Installing a vertical handgrip on a semiautomatic that already has a folding stock creates a banned combination.5California Legislative Information. California Penal Code 30515 – Assault Weapons Multiburst trigger activators, which let a single trigger pull fire multiple rounds, are separately banned under Penal Code 32900, with a penalty of up to one year in county jail or a state prison sentence.7California Legislative Information. California Penal Code 32900 – Multiburst Trigger Activator
Buying Shells
Ammunition has its own background check, separate from the one you cleared for the gun. The California Department of Justice must complete an eligibility check before every sale. You’ll present a California driver’s license, state ID card, or military ID at the counter.4State of California – Department of Justice – Office of the Attorney General. Ammunition Purchase Authorization Program Frequently Asked Questions The check costs $5 as of July 2025.8State of California – Department of Justice – Office of the Attorney General. Regulations: Ammunition Purchase Fee If your California ID reads “FEDERAL LIMITS APPLY” on the front, you’ll need proof of lawful presence too, such as a passport or certified birth certificate. The vendor runs everything at the point of sale.
Storing a Shotgun at Home
California treats careless storage as a crime. Under Penal Code 25100, keeping a shotgun somewhere a child is likely to reach without permission, if the child actually gets to it, is criminal storage of a firearm. The charge escalates if the child then takes the gun off the property or causes injury.
Penal Code 25135 adds a second rule for anyone living with a person prohibited from possessing firearms: every firearm in the home must be kept in a locked container or fitted with a firearm lock.9California Legislative Information. California Penal Code 25135 – Criminal Storage of Firearm No exception exists for keeping the shotgun close at hand.
Transporting a Shotgun
Transport rules for shotguns and rifles are looser than for handguns, and that difference confuses a lot of owners. The California Department of Justice confirms that shotguns and rifles are not required to be in a locked container. They must, however, be fully unloaded inside a vehicle.10State of California – Department of Justice – Office of the Attorney General. Transporting Firearms in California
Under Penal Code 25850, carrying a loaded shotgun in a vehicle or any public place is a misdemeanor punishable by up to one year in county jail and a $1,000 fine. The charge becomes a felony if you have a prior felony conviction, the firearm is stolen, or you’re an active participant in a criminal street gang.
Some cities go further than state law. Certain municipalities require any unattended firearm in a vehicle to be locked in a container or in the trunk, long guns included. Check your local ordinance before you assume the state rule is the only one that matters.
Hunting Rules for Shotguns
If you’re hunting game birds or mammals, your shotgun’s total capacity is capped at three shells across magazine and chamber. Higher-capacity models need a one-piece plug that cannot come out without disassembly.11California Department of Fish and Wildlife. California Outdoors Q&A
Since July 2019, all hunting ammunition must be nonlead. Lead shot and lead slugs are illegal for taking any wildlife on public or private land. Wildlife officers can inspect ammunition in the field and seize a cartridge for testing if they suspect lead.12California Department of Fish and Wildlife. Nonlead Ammunition in California Patterning your shotgun with nonlead loads at the range before a hunt saves surprises later, because different shells behave differently.
Reporting a Lost or Stolen Shotgun
If your shotgun is lost or stolen, notify local law enforcement in the jurisdiction where it happened within five days of finding out. If you get it back, you have another five days to tell the same agency.13California Legislative Information. California Penal Code 25250 Antique firearms are the only exception. Missing the deadline is itself a violation, so report even if you expect to recover the gun.
Transferring a Shotgun to Someone Else
Private transfers must go through a licensed dealer, who runs the same background check and applies the same 10-day wait as a retail sale. The dealer charges a processing fee.
Transfers between parents, children, grandparents, and grandchildren qualify for a familial transfer exemption. The recipient still needs to pass a background check, hold a Firearm Safety Certificate, and register the firearm with the California Department of Justice. A shotgun coming from out of state has to ship directly to a California-licensed dealer; you cannot bring it across the border yourself to hand off.
Siblings, cousins, aunts, and uncles do not qualify. Their transfers follow the standard private-party route through a dealer, exactly like a sale between strangers.
Penalties for Common Violations
Penalties depend heavily on the specific offense. Distributing an assault-weapon-classified shotgun (manufacturing, importing, selling, or giving one away) is a felony under Penal Code 30600, carrying four, six, or eight years in state prison.14California Legislative Information. California Penal Code 30600 – Unlawful Acts Relating to Assault Weapons and .50 BMG Rifles
Possessing a short-barreled shotgun is a wobbler under Penal Code 33215: up to one year in county jail as a misdemeanor, up to three years in state prison as a felony.6California Legislative Information. California Penal Code 33215
Brandishing a shotgun threateningly is a misdemeanor under Penal Code 417, with a minimum of three months in county jail. Doing it in front of a peace officer turns it into a wobbler with up to three years in state prison.15California Legislative Information. California Penal Code 417 – Drawing or Exhibiting Firearm or Deadly Weapon Firing a shotgun with gross negligence in a way that could injure or kill someone is punishable under Penal Code 246.3 by up to one year in county jail or a state prison sentence.16California Legislative Information. California Penal Code 246.3
Many of these are wobblers, meaning prosecutors decide between a misdemeanor and felony based on the facts. A felony conviction on any of them permanently bars you from possessing a firearm in California under Penal Code 29800.1California Legislative Information.
