Gun registration in California started in 1923, when a new state law required every licensed dealer to record each sale of a pistol, revolver, or other concealable firearm and send a duplicate record to local law enforcement the same day.1Duke Center for Firearms Law. 1923 Cal Stat 698-99 – An Act to Control and Regulate the Possession, Sale and Use of Pistols, Revolvers, and Other Firearms Capable of Being Concealed Upon the Person That dealer-recording rule, which actually originated in a 1917 statute the 1923 law carried forward, is the beginning of the registration system California still runs today. Over the following century the state added assault weapons in 1989, long guns in 2014, and self-manufactured firearms in 2018, until nearly every legally owned firearm in the state ended up in a central database called the Automated Firearms System.
1923: Handgun Sales Enter the Record
The 1923 legislation covered the possession, sale, and use of concealable firearms and specifically provided for registering all sales of pistols, revolvers, and similar weapons.1Duke Center for Firearms Law. 1923 Cal Stat 698-99 – An Act to Control and Regulate the Possession, Sale and Use of Pistols, Revolvers, and Other Firearms Capable of Being Concealed Upon the Person Under the retained 1917 provisions, every dealer kept a register showing the date, the salesman, the location, and the make, model, serial number, and caliber of each concealable firearm sold. The dealer mailed a duplicate sheet to the local police chief, city marshal, or county clerk on the evening of the sale day.
That point-of-sale paperwork is the direct ancestor of the modern Dealer Record of Sale, or DROS, process. The state eventually centralized the records under the Department of Justice instead of leaving them scattered across local agencies, and today every handgun sale through a licensed dealer generates a permanent entry in the Automated Firearms System that links the buyer’s identity to the weapon’s serial number.2State of California – Department of Justice – Office of the Attorney General.

1989: Assault Weapons Added
The next big expansion was the Roberti-Roos Assault Weapons Control Act of 1989, now codified starting at Penal Code section 30500.3California Department of Justice. Assault Weapons Identification Guide Roberti-Roos named specific rifles, pistols, and shotguns by make and model and declared them assault weapons. That designated list now sits in Penal Code section 30510 and has grown through additions by the Attorney General and later legislation covering the AK and AR-15 series.4California Legislative Information.

Owners who already possessed these firearms got a registration window to put them on the books with the Department of Justice. The original deadline fell in January 1991, and the Legislature then extended it to March 30, 1992. Missing the window made the firearm illegal to possess in California regardless of when it was purchased. Later amendments broadened the definition to include firearms with specific physical features, and each change opened a new registration period with its own hard deadline.
2014: Long Guns Join the Registry
Rifles and shotguns stayed off the registration books for decades. Before 2014, a long gun sale went through a DROS form and a background check, but state law actually required the Department of Justice to destroy those records within five days of clearing the buyer. Peace officers and DOJ employees were prohibited from retaining or compiling long gun transaction information, and violating that prohibition was itself a misdemeanor.5California Legislative Information. AB 809 Assembly Bill – Bill Analysis
Assembly Bill 809 reversed that framework. Effective January 1, 2014, the law repealed the destruction requirement and conformed long gun record retention to the rules already governing handguns. Every rifle and shotgun sold through a licensed dealer from that date forward produces a permanent entry in the Automated Firearms System.5California Legislative Information. AB 809 Assembly Bill – Bill Analysis A long gun bought from a California dealer on or after January 1, 2014, is linked to its buyer in the state database for good. Long guns bought earlier are not, because those records were destroyed under the pre-2014 rule.
2018: Self-Manufactured Firearms
The most recent expansion covered firearms built outside traditional manufacturing channels. Assembly Bill 857, which became fully operative in 2018, responded to the fact that homemade firearms carried no serial numbers and existed entirely outside state records. Under Penal Code section 29180, anyone who manufactures or assembles a firearm must first apply to the Department of Justice for a unique serial number through the California Firearms Application Reporting System.6State of California – Department of Justice – Office of the Attorney General. Unique Serial Number Application
The initial application fee is $46.19, which covers a firearms eligibility background check and one serial number. Each additional number in the same transaction costs $15.6State of California – Department of Justice – Office of the Attorney General. Unique Serial Number Application Once the application is approved, the builder has 10 calendar days from the date of manufacturing or assembling the firearm to engrave or permanently affix the assigned serial number, and then uploads photographs through the online system to confirm compliance. New residents who bring unserialized firearms into California must also apply for a serial number within 60 days of arrival.7State of California – Department of Justice – Office of the Attorney General. Regulations: Self Manufactured and Self Assembled Firearms
Where the Timeline Stands Today
Taken together, these four milestones mean virtually every legally owned firearm in California now appears somewhere in the Automated Firearms System: handguns since 1923, assault weapons after Roberti-Roos registration windows beginning in 1989, long guns sold on or after January 1, 2014, and self-built firearms since 2018. The gaps that remain are mostly historical, covering long guns sold before 2014 whose records were destroyed under the old rule, and firearms that existed in California before the registration category covering them took effect.
What California’s Registry Does Not Cover
California’s system is a state creation and does not mirror a comparable federal registry. Federal law has no registry for ordinary handguns, rifles, or shotguns. The Bureau of Alcohol, Tobacco, Firearms and Explosives maintains the National Firearms Registration and Transfer Record, but that database only tracks short-barreled rifles and shotguns, machine guns, silencers, destructive devices, and certain other specialized weapons regulated by the National Firearms Act.8Bureau of Alcohol, Tobacco, Firearms and Explosives. National Firearms Act Every manufacturer, importer, and transferor of those items must register them with the ATF, and proof of registration must be retained and made available on request.9Office of the Law Revision Counsel. 26 USC 5841 If you own an NFA-regulated item in California, the federal and state registration requirements apply independently.
