California-legal .45 ACP pistols fall into two groups: models currently on the state’s Roster of Certified Handguns, which licensed dealers can sell new, and off-roster models, which residents can still legally own but must acquire through specific channels like private-party transfers, family gifts, or a move into the state. Either way, the buyer clears a background check, waits 10 days, and takes delivery with a 10-round magazine.
The Handgun Roster and What’s on It
Penal Code section 32000 bars dealers from selling any handgun not listed on the Roster of Certified Handguns.1California Legislative Information. California Penal Code 32000 To get on the roster, a pistol must pass drop-safety and firing-reliability testing at a DOJ-certified lab.2State of California – Department of Justice – Office of the Attorney General. Handguns Certified for Sale Under Penal Code section 31910, any centerfire semiautomatic pistol added after July 2022 must also have a chamber load indicator and, if it accepts a detachable magazine, a magazine disconnect.3California Legislative Information. California Penal Code 31910 Most manufacturers have declined to redesign current models to meet those requirements, so the .45 ACP options on dealer shelves are almost entirely designs grandfathered in years ago.
The roster shifts, and the DOJ’s searchable database is the only authoritative source at any given moment.2State of California – Department of Justice – Office of the Attorney General. Handguns Certified for Sale A few platforms have stayed on it consistently. The 1911 is well represented, with Springfield Armory and Kimber maintaining multiple variants such as the Springfield Loaded and the Kimber Custom II. The Sig Sauer P220 remains available for buyers who prefer a hammer-fired, double-action/single-action design. Striker-fired options are thin. The Glock 21 Gen 3 is on the roster; the Gen 4 and Gen 5 are not, because they were introduced after the newer feature requirements took effect. That pattern repeats across brands: newer generations of popular pistols are absent from California retail.
Owning an Off-Roster .45 ACP
The roster controls what dealers can sell as new inventory. It does not control what individuals can own. Several legal routes exist to acquire an off-roster .45 ACP.
Private Party Transfer
Any California resident who already owns an off-roster pistol can sell it to another resident through a private party transfer. The transfer still runs through a licensed dealer, who handles the background check, DROS paperwork, and 10-day waiting period.4State of California – Department of Justice – Office of the Attorney General. Frequently Asked Questions You’ll pay the $37.19 DROS fee plus a dealer processing fee, typically around $10. Because demand outstrips supply, off-roster pistols often sell at a premium over what the same gun costs new in other states.
Intrafamilial Transfer
Penal Code section 27875 permits transfers between immediate family without going through a dealer. Parents, grandparents, children, grandchildren, siblings, and spouses qualify. The transfer can come from out of state, so a parent in Arizona can lawfully gift an off-roster .45 ACP to their adult child in California. The recipient needs a valid Firearm Safety Certificate and must report the transfer to the DOJ within 30 days.5California Legislative Information. California Penal Code 27875 The magazine still has to comply with California’s 10-round cap.
Moving to California With a Pistol You Already Own
New residents who already own an off-roster .45 ACP can bring it into the state as a “personal firearm importer.” You have 60 days after establishing residency to report the firearm to the DOJ using Form BOF 4010A with a $19 fee.6California Legislative Information. California Penal Code 27560 The other options are selling or transferring it through a licensed dealer or surrendering it to law enforcement.7State of California – Department of Justice – Office of the Attorney General. Firearms Information for New California Residents Miss the 60-day window and you’re in possession of an unregistered firearm.
Law Enforcement Exemption
Sworn peace officers can buy off-roster handguns under Penal Code section 32000(b)(4), covering police, sheriff’s, CHP, corrections, district attorney, and federal agency personnel.1California Legislative Information. California Penal Code 32000 An officer who lawfully purchases an off-roster pistol can later sell it to a non-exempt resident through a private party transfer, with a notice filed to the DOJ within 72 hours. That secondary market is one of the main ways off-roster .45 ACPs end up in civilian hands in California.
Who Can Buy and How Often
You must be at least 21 to buy any handgun in California.8State of California – Department of Justice – Office of the Attorney General. Frequently Asked Questions Penal Code section 27535 limits purchases to one handgun or semiautomatic centerfire rifle per 30 days, with exceptions for law enforcement, licensed curio and relic collectors holding a Certificate of Eligibility, and replacements for lost or stolen firearms. As of mid-2024, a federal court injunction blocked enforcement of that limit, but injunctions can be lifted or modified, so confirm the current status before planning multiple purchases in a month.4State of California – Department of Justice – Office of the Attorney General. Frequently Asked Questions
What to Bring to the Dealer
- A Firearm Safety Certificate. You earn it by passing a 30-question written test on firearm safety and California law with at least 75%. The test costs $25 through a DOJ-certified instructor, usually at the dealership, and the certificate is good for five years.9State of California – Department of Justice – Office of the Attorney General. Firearm Safety Certificate Program
- A California driver’s license or state ID. Military ID works if you also present permanent duty station orders showing a California posting.8State of California – Department of Justice – Office of the Attorney General. Frequently Asked Questions
- Proof of California residency, separate from your ID. A utility bill from the past three months, a residential lease, a property deed, or military duty station orders all qualify.10California Legislative Information. California Penal Code 26845
The name and address on your residency document should match your ID. A mismatch will stall the sale.
At the Counter: DROS, the 10-Day Wait, and Pickup
Once your paperwork checks out, the dealer submits the Dealer’s Record of Sale electronically. You pay a $37.19 state fee at that point, in addition to whatever the dealer charges for the transaction itself.4State of California – Department of Justice – Office of the Attorney General. Frequently Asked Questions Then the 10-day waiting period runs. No firearm can be delivered within 10 days of the application, regardless of how fast the background check clears.11California Legislative Information. California Penal Code 26815 If the DOJ can’t reach an eligibility decision within 30 days, the dealer gets notice and may release the firearm at their discretion.12State of California – Department of Justice – Office of the Attorney General. Bureau of Firearms
When you come back to pick up the pistol, you perform a safe handling demonstration in front of the dealer. For a semiautomatic .45 ACP that means removing the magazine, locking the slide back to inspect the chamber, loading a dummy round into the magazine, inserting it, cycling the slide, removing the magazine again, locking the slide to eject the dummy round, and applying any safety mechanisms, all with proper muzzle awareness and trigger discipline. Fail the demonstration and the dealer cannot release the gun that day.
You also need to leave with a DOJ-approved Firearm Safety Device such as a cable or trigger lock. If you already own a compliant gun safe, you can sign an affidavit under penalty of perjury attesting to that, and the dealer waives the device requirement.13State of California – Department of Justice – Office of the Attorney General. Firearm Safety Devices Otherwise, plan on buying an approved lock at pickup.
Magazine Cap and Feature Rules
California limits magazines to 10 rounds. Penal Code section 32310 makes it illegal to buy, sell, import, or possess any magazine holding more.14California Legislative Information. California Penal Code 32310 Most .45 ACP magazines run between 7 and 13 rounds depending on the model, so this affects double-stack designs like the Glock 21 more than single-stack 1911s. A pistol that ships from the factory with a higher-capacity magazine has to come with a blocked or reduced-capacity magazine at the California dealer.
Feature rules apply as well. Under Penal Code section 30515, a semiautomatic pistol with a detachable magazine becomes an assault weapon if it has a threaded barrel that can accept a suppressor or flash hider, a second handgrip, a barrel shroud that isn’t just the slide, or a magazine well outside the pistol grip.15California Legislative Information. California Penal Code 30515 Factory .45 ACPs generally don’t have these features, but aftermarket parts can cross the line. Threading a 1911 barrel for a suppressor, for instance, turns the pistol into an assault weapon under state law.
Transport
Without a concealed carry permit, you cannot carry a loaded handgun in your vehicle. For transport, the pistol must be unloaded and either locked in the trunk or in a locked container.16State of California – Department of Justice – Office of the Attorney General. Transporting Firearms in California A locked container is a fully enclosed case secured by a padlock, key lock, or combination lock. The glove compartment and center console don’t qualify, even if they lock. A padlocked pistol case in the back seat does.
Storage and Child Access
California holds owners responsible when minors reach improperly stored firearms. If you keep a loaded firearm on premises you control and a child under 18 obtains it and causes injury, carries it in public, or uses it, you face misdemeanor or felony charges depending on what happens.17State of California – Department of Justice – Office of the Attorney General. Firearm Safety The DOJ’s guidance is to store guns unloaded, locked with a safety device, inside a locked container, with ammunition separate. The rule reaches any child who gains access, not just children who live with you, so visiting grandchildren and neighbors count.
Buying Ammunition
Each .45 ACP ammunition purchase in California triggers its own background check at the point of sale, with a fee of at least $5. All sales happen face-to-face at a licensed ammunition vendor in California. Out-of-state residents generally can’t buy ammunition in the state, and California residents can’t lawfully bring in ammunition ordered online or from out of state without routing it through a licensed vendor for transfer.
