California Gun Laws 2025: Complete Guide to the Most Regulated State
California has the most complex and restrictive firearms regulatory framework of any U.S. state. The state layers dozens of regulations on top of federal law: an assault weapons ban with unique feature-based definitions, a 'safe handgun roster' limiting which handguns can be sold by dealers, a mandatory 10-day waiting period for all purchases, one-handgun-per-30-day purchase limits, universal background checks for all transfers (including private sales), a Firearm Safety Certificate requirement, ammunition purchase background checks, and red flag laws — among many others. Despite these restrictions, California still has millions of lawful gun owners and thousands of active FFL dealers. This guide navigates the full regulatory landscape for 2025.

The Assault Weapons Ban: Feature-Based Restrictions
California's assault weapons ban (Penal Code § 30500-30530) is among the most complex firearm regulations in the country. Unlike a simple ban on named models, California uses a 'features test' that prohibits certain combinations of firearm characteristics. For semiautomatic centerfire rifles, a firearm is an 'assault weapon' if it has: a detachable magazine AND any one of the following features: pistol grip, thumbhole stock, folding/telescoping stock, grenade/flare launcher, flash suppressor, or forward pistol grip. Alternatively, a fixed-magazine rifle that accepts more than 10 rounds is an assault weapon regardless of features.
For semiautomatic centerfire pistols, the features test prohibits: a detachable magazine AND any one of: a threaded barrel capable of accepting a flash suppressor/silencer/forward handgrip, a second handgrip, a shroud surrounding the barrel (allowing the shooter to fire without burning their hand), or the capacity to accept a detachable magazine at some location outside the pistol grip. Semiautomatic shotguns are assault weapons if they have: a folding/telescoping stock, a pistol grip, a thumbhole stock, or a detachable magazine.
California gun owners have responded to the assault weapons ban through 'featureless' rifle builds — configurations that comply with the law by removing all prohibited features while retaining a detachable magazine. Common featureless builds use: a fin grip (replacing the pistol grip), a fixed stock (no telescoping/folding), no flash suppressor (muzzle brake only), and no vertical foregrip. Alternatively, 'fixed magazine' (maglocked) configurations use a device that requires disassembly of the action to release the magazine, allowing all features but limiting magazine changes.
The assault weapons ban has been the subject of significant litigation. In Miller v. Bonta (2021), a federal district court struck down the ban as unconstitutional. The Ninth Circuit initially stayed the ruling, and the case was remanded following the Supreme Court's Bruen decision (2022). As of 2025, the case remains in litigation and the ban remains enforceable. Gun owners should continue to comply with the current law while legal challenges proceed. Possession of a properly registered assault weapon (registered before the applicable deadline) remains legal, but new registrations are not accepted.

The Safe Handgun Roster: What You Can and Cannot Buy
California maintains a 'Roster of Certified Handguns' (Penal Code § 31900-31910) — a list of handgun models approved for retail sale by licensed dealers. Only handguns that have passed specific safety testing AND include required features may be sold new by California FFLs. Since 2013, new models must include a 'microstamping' capability (engraving a unique microscopic identifier on cartridge cases when fired). Because no manufacturer has commercially implemented microstamping, virtually no new models have been added to the roster since 2013, and the roster has shrunk each year as existing models are removed when manufacturers fail to renew certifications.
As of 2025, the roster contains approximately 250 handgun models — down from over 1,200 at its peak. Entire categories of modern handguns are unavailable through California dealers: most striker-fired pistols introduced after 2013, all new Glock Gen 5 models, most new Smith & Wesson M&P models, most SIG Sauer P320/P365 variants, and virtually all new production handguns from any manufacturer. This creates a situation where California residents have access to a fraction of the handgun market available in other states.
There are limited exceptions to the roster requirement. Off-roster handguns may be acquired through: private party transfers (PPT) from another California resident who already owns the handgun (requiring an FFL to process the transfer), intrafamilial transfers (parent-child, grandparent-grandchild), law enforcement sales (officers may buy off-roster for personal use and later transfer via PPT), and inheritance (from a deceased family member). This has created a secondary market where off-roster handguns command significant premiums — a Glock Gen 5 that retails for $550 in other states may sell for $1,200-$2,000 in California through a PPT.
The roster has faced multiple legal challenges. In Boland v. Bonta, plaintiffs argue the microstamping requirement is impossible to meet (since the technology doesn't exist commercially) and therefore constitutes a de facto ban on new handgun models. The case is proceeding through federal courts following the Bruen decision. Gun owners should monitor this litigation as a favorable ruling could dramatically expand handgun availability in California. Until then, the roster remains fully enforceable.

Purchase Requirements: FSC, Waiting Period, and Limits
California imposes more purchase requirements than any other state. Before you can buy a firearm, you must first obtain a Firearm Safety Certificate (FSC) by passing a 30-question written test at a licensed dealer (true/false and multiple choice, 75% passing score, $25 fee, valid for 5 years). The test covers: safe storage, safe handling, California firearm laws, and basic firearms operation. Exemptions exist for law enforcement, military, licensed hunters, and existing California Concealed Carry Weapon (CCW) permit holders.
All firearm purchases from dealers are subject to a mandatory 10-day waiting period — no exceptions (with very narrow exceptions for certain law enforcement and entertainment industry transactions). The 10-day clock starts when the Dealer Record of Sale (DROS) is submitted to the California DOJ. You cannot take possession until the full 10 days have elapsed AND the background check has been approved. If the background check is delayed beyond 10 days, you wait longer. The 10-day period applies to every purchase — even if you already own firearms and passed a background check yesterday.
California limits handgun purchases to one per 30-day period (with limited exceptions for private party transfers, law enforcement, and curio/relic collectors). Starting January 1, 2024 (SB 1327's provisions upheld pending litigation), semiautomatic centerfire rifles are also subject to the one-per-30-day limit. This means a California resident cannot buy more than one handgun or one semiautomatic centerfire rifle within any 30-day window from licensed dealers.
Additional purchase requirements include: valid California ID or driver's license showing current address (if your address has changed, you need supplemental proof of residency — utility bill, lease, or vehicle registration), proof of residency if using a California ID without a current address (two documents showing your current address), and for handguns specifically, proof of safe storage capability (presenting a California DOJ-approved lock or lockbox, or signing an affidavit that you own an approved safe). The cumulative effect of these requirements makes purchasing a firearm in California a significantly more complex process than in most other states.

Magazine Capacity Restrictions
California Penal Code § 32310 prohibits the sale, import, manufacture, and transfer of magazines capable of holding more than 10 rounds. Possession of such magazines was also banned effective July 1, 2017 (Proposition 63 / SB 1446). However, during a brief period in late March-early April 2019 (following the Duncan v. Bonta district court ruling striking down the possession ban), Californians legally purchased standard-capacity magazines — these magazines acquired during 'Freedom Week' are legal to possess, though subsequent purchases remain prohibited.
The magazine ban applies to all firearms: handguns, rifles, and shotguns. Tubular magazines on lever-action rifles and pump shotguns that exceed 10 rounds are included. Fixed magazines over 10 rounds are banned (relevant for some older firearms). Magazine repair kits that can be assembled into magazines over 10 rounds are treated as large-capacity magazines themselves. Possession of a non-compliant magazine (not acquired during Freedom Week) is a wobbler offense — prosecutable as either a misdemeanor or infraction.
Duncan v. Bonta (formerly Duncan v. Becerra) challenged the magazine ban on Second Amendment grounds. The case has been through multiple rounds of litigation: the district court struck down the law, the Ninth Circuit reversed, the Supreme Court vacated and remanded following Bruen, and the case is back before the Ninth Circuit as of 2025. The ban remains enforceable during litigation. If ultimately struck down, standard-capacity magazines would again become legal to purchase and possess in California — a development that would significantly affect the California firearms market.
For practical compliance: California gun owners are limited to 10-round magazines for all firearms (unless they possess Freedom Week magazines, which have no identifying marks distinguishing them from banned magazines — making enforcement challenging). Many manufacturers produce California-compliant 10-round versions of their standard magazines. Some firearms that ship from the factory with standard-capacity magazines are available in California with 10-round alternatives (often marked 'CA compliant' or 'LEO/MIL restriction').

Universal Background Checks and Private Transfers
California requires background checks for ALL firearm transfers — including private sales between individuals. There is no private sale exemption in California. Every transfer of a firearm (defined broadly as any change of ownership or possession) must be processed through a licensed dealer, with both parties present, with a full background check and 10-day waiting period. The transfer fee is $37.19 (DROS fee) plus the dealer's transfer fee (typically $35-$100 per firearm).
This universal background check requirement extends beyond traditional sales to include: gifts, loans exceeding certain timeframes, returns of borrowed firearms, and virtually any situation where a firearm passes from one person to another. There are limited exemptions: transfers between immediate family members (parent, child, grandparent, grandchild — NOT siblings, NOT spouses through 2025 legislation) may be done through a simplified intrafamilial process (still requires background check but may use a streamlined form), and temporary transfers at licensed shooting ranges or while hunting.
The California DOJ maintains the Dealer Record of Sale (DROS) system, which records every firearm transaction processed through a dealer. This creates a de facto registration system — the DOJ knows who purchased each firearm, when, and from whom. While California doesn't call it 'registration,' the practical effect is that the state maintains comprehensive records of firearm ownership. This database is used by law enforcement for tracing investigations and for cross-referencing against newly prohibited persons (APPS — Armed Prohibited Persons System).
For California residents purchasing firearms from online retailers or out-of-state sources, ALL transfers must go through a California FFL. The receiving dealer processes the DROS, conducts the background check, enforces the 10-day waiting period, verifies FSC and safe storage requirements, and ensures the firearm complies with all California regulations (assault weapons features test, roster compliance for handguns, magazine capacity). If the firearm arrives in a non-compliant configuration (standard magazines, prohibited features), the dealer must refuse the transfer or modify the firearm to comply before releasing it.

Concealed Carry in California: Post-Bruen Changes
California's concealed carry landscape changed dramatically following the Supreme Court's NYSRPA v. Bruen decision (June 2022), which struck down New York's 'proper cause' requirement and, by extension, California's similar 'good cause' requirement for CCW issuance. Prior to Bruen, California counties varied widely in CCW issuance — rural counties were effectively shall-issue while urban counties (Los Angeles, San Francisco, Santa Clara) denied virtually all applications. Post-Bruen, California shifted to a shall-issue system where applicants meeting objective criteria must be issued a permit.
In response to Bruen, the California Legislature passed SB 2 (effective January 1, 2024), which created an extensive list of 'sensitive places' where concealed carry is prohibited even with a permit: all public transit, parks, playgrounds, places of worship, financial institutions, hospitals, bars and restaurants serving alcohol, entertainment venues, libraries, museums, zoos, children's activity areas, and many more. A federal court temporarily blocked much of SB 2's sensitive places list, and the case (May v. Bonta) is actively litigated. The changing injunction landscape makes it critical for California CCW holders to stay current on court orders.
The CCW application process in California is administered by the county sheriff (or police chief in some cities). Requirements include: being at least 21, being a California resident, completing 16 hours of training (initial; 4 hours for renewal), passing a psychological evaluation (some counties), passing a background check, demonstrating good moral character (narrowed from 'good cause' post-Bruen), and paying application fees ($100-$300 depending on county). Processing times vary dramatically — from 30 days in gun-friendly counties to 6+ months in Los Angeles and San Francisco.
California CCW permits are issued with specific firearm restrictions — you must qualify with each handgun you intend to carry, and those firearms are listed on your permit. You may only carry handguns listed on your permit (maximum varies by county, typically 3-5 firearms). Adding a firearm to an existing permit requires re-qualification with that specific handgun. Rifles and shotguns cannot be carried concealed under a California CCW. The permit is valid statewide regardless of the issuing county.

Ammunition Restrictions and Background Checks
Since July 1, 2019, California requires a background check for all ammunition purchases (Proposition 63 / AB 1235). Every time you buy ammunition — whether at a store, online, or at a gun show — the seller must verify your identity against the California DOJ's Automated Firearms System (AFS) to confirm you are not a prohibited person AND that you are a registered firearm owner in California. This 'standard eligibility check' costs $1 per transaction and is instant for most buyers who already have firearms registered in the DROS system.
If you are NOT in the AFS as a registered firearm owner (perhaps because you acquired firearms before electronic record-keeping, moved to California with firearms, or inherited firearms without processing through a dealer), the $1 instant check will fail. You must then undergo a 'basic eligibility check' — a full background check costing $19 that takes 1-10 business days. Many new California residents and long-time gun owners who acquired firearms through pre-DROS-era private sales encounter this issue. The solution is to register your firearms with the DOJ through a Voluntary Registration form ($19 per firearm).
Online ammunition purchases must ship to a licensed ammunition vendor (typically an FFL) within California. You cannot have ammunition shipped directly to your home. The receiving vendor processes the eligibility check when you pick up. This adds cost (vendor fees of $5-$20 per transaction) and inconvenience (requiring a trip to the vendor). Some California gun owners travel to Nevada, Arizona, or Oregon to purchase ammunition, but importing ammunition into California without going through a vendor is illegal (Penal Code § 30312) — a misdemeanor offense.
Certain ammunition types are entirely prohibited in California regardless of background check status. Armor-piercing handgun ammunition (as defined by federal law), tracer ammunition in certain circumstances, and .50 BMG ammunition (banned under Penal Code § 30610) cannot be sold or possessed. Lead ammunition has been banned for hunting throughout California since 2019 (AB 711 / Ridley-Tree Condor Preservation Act), requiring the use of non-lead (copper, copper alloy) projectiles for all hunting on all lands. Lead ammunition remains legal for target shooting and self-defense use.

Storage, Transport, and Carry Outside the Home
California requires that firearms be stored in a manner that reasonably prevents access by unauthorized persons — particularly children. Under Penal Code § 25100-25140 (Criminal Storage), if a child under 18 gains access to a firearm that was not stored in a locked container or with a trigger lock, the owner is criminally liable for negligent storage (up to a felony if the child causes death or great bodily harm). All firearm sales must include a California DOJ-approved firearm safety device (cable lock, trigger lock, or approved lockbox). Buyers must present proof of safe storage (device or affidavit of safe ownership).
Transporting firearms in California is heavily regulated. For most persons without a CCW, handguns must be: unloaded, in a locked container (specifically NOT including the utility compartment or glove compartment of a motor vehicle), and transported directly to or from specified locations (range, dealer, hunting, etc.). Long guns must be unloaded during transport in a vehicle. A locked container means the trunk, or a fully enclosed locked case/box (Penal Code § 16850). Simply placing a handgun in the glove box — even unloaded — is not legal transport without a CCW.
Open carry is entirely banned in California — both loaded (Penal Code § 25850) and unloaded (Penal Code § 26350-26405). There is no exception for open carry in public, regardless of whether the firearm is loaded or unloaded, and regardless of whether you have a CCW (the CCW authorizes concealed carry only). The only exceptions are on your own property, at a fixed place of business you own, and while engaged in legal hunting activities in appropriate areas.
The combination of no open carry, restricted concealed carry (CCW required), strict transport rules, and the 'locked container' requirement means that for most California gun owners without a CCW, the only legal way to have a firearm outside the home is: unloaded, in a locked hard-sided case, separate from ammunition (ammunition may be in the same locked container but cannot be in a loaded magazine inserted into the firearm), during direct transport to or from a permitted destination. Any deviation from this (stopping for extended errands during transport, having the gun accessible rather than locked) can constitute a criminal violation.
