California Firearms Laws Explained
Owning a Glock 19 in California isn’t the same as owning one in Texas. The state’s complex web of regulations, from the Handgun Roster to the Assault Weapons Ban, directly dictates what you can buy, how you can configure it, and where you can take it. Getting it wrong isn’t just inconvenient—it’s a felony. This breakdown cuts through the legal jargon to give you the operational knowledge you need.
The California Handgun Roster
The Roster of Certified Handguns is a California-specific hurdle. For a new semi-automatic pistol to be sold by a dealer to a private citizen, it must be on this state-approved list. The requirements include microstamping technology, which is functionally unavailable, effectively freezing the list. This means popular new models like the latest SIG P365 variants or the Springfield Hellcat Pro are not roster-approved for standard sale. Your options are to purchase a used, off-roster handgun from another California resident via private party transfer (PPT) at a significant markup, or acquire one through a few narrow exemptions like intra-familial gift from an out-of-state parent. At Conwayhuntingsupply, we clearly label which pistols, like the Springfield Armory XD Mod.4, are roster-compliant for direct shipment to your FFL.
Assault Weapons & Feature-Based Bans
California’s Assault Weapons Control Act (AWCA) prohibits firearms classified as “assault weapons.” For semi-automatic, centerfire rifles, this is primarily a feature-based test. If a rifle has a detachable magazine and any one of several “evil features” (like a pistol grip, flash hider, or telescoping stock), it is banned. The common workaround is a “featureless” build: remove the offending features by using a fixed stock, a fin grip that prevents wrapping the thumb, and a muzzle brake instead of a flash hider. Alternatively, a “fixed magazine” kit, like the AR MagLock, legally makes the magazine non-detachable without disassembling the action, allowing you to keep features like a pistol grip. Pistols and shotguns have their own, even more restrictive, feature lists.
Magazine Capacity Restrictions
It is illegal to manufacture, import, keep for sale, offer for sale, or give away any magazine capable of holding more than 10 rounds. Possession of such “large-capacity magazines” (LCMs) is also generally illegal. There was a brief freedom week in 2019 when possession became legal, but that window has closed. This law impacts nearly every modern firearm. A standard Glock 17 ships with a 17-round magazine; to own one in California, you must either use a permanently blocked (pinned) 10-round magazine or possess it under very specific, narrow exemptions. This is why many firearms shipped to California come with state-compliant 10-round mags. Always verify capacity when purchasing ammunition or magazines.
The 10-Day Wait & Ammunition Background Check
All firearm purchases from a dealer require a 10-day waiting period, starting when the DROS (Dealer’s Record of Sale) information is submitted to the DOJ. This is a mandatory cooling-off period, no exceptions. For ammunition, since 2019, you must pass an instant background check for each purchase, with a $1 fee. You must be 21 for handgun ammo and 18 for rifle/shotgun ammo. The ammo check runs through the California Ammunition Purchase Records database. Having a current Curio & Relic (C&R) FFL with a COE (Certificate of Eligibility) or having a firearm registered to you in the state’s AFS database can streamline this process. Purchasing defensive ammunition requires the same check as range ammo.
Transportation and Storage Requirements
You cannot legally carry a loaded firearm in public without a permit, which are nearly impossible to obtain in many counties. During transport, unloaded firearms must be in a locked container. The trunk of a car counts as a locked container if it’s separate from the passenger compartment. For handguns, the locked container is mandatory. For long guns, they must be unloaded but do not explicitly require a locked container, though using one is the best practice to avoid any ambiguity. At home, if a child could potentially access the firearm, you must store it in a locked container or disable it with a state-approved safety device. This is a strict liability law.
Frequently Asked Questions
Can I buy a pistol that’s not on the Roster if I’m moving to California?
Yes, but you must act before establishing residency. New residents moving into California have a 60-day window to report any firearms they bring with them using a New Resident Report of Firearm Ownership (BOF 4010A). You can bring off-roster handguns you already own, but they must be California-legal (10-round mags, no threaded barrels for semi-autos). You cannot move to California with the intent to sell them.
Is it legal to own a .50 BMG rifle in California?
No. California Penal Code 12280 explicitly prohibits the possession, sale, or transfer of any .50 BMG caliber rifle. This is separate from the assault weapon laws. The ban is based on the cartridge itself. Some similar-caliber rifles, like those chambered in .416 Barrett, are not banned by this specific statute, but they may still fall under the assault weapon rules based on their features.
Absolutely not. Bump stocks and any other “multiburst trigger activators” are completely banned in California under Penal Code 16930. This includes devices like the SSAR-15 OGR. Possession, sale, or transfer is a felony. This state ban was in place years before the federal rule change.
