The Sig Sauer P365 is legal to buy in California, but only in the specific California-compliant versions Sig Sauer submitted to the state’s Roster of Certified Handguns in late 2023. Standard P365 configurations sold in other states remain off-roster and cannot be purchased new at a California gun store. If you want one of those, you’re looking at a private party transfer or a narrow exemption, usually at a steep premium.
What You’re Actually Buying With a CA-Compliant P365
A California P365 is a factory-modified version of the pistol, not a standard model with aftermarket parts. Sig Sauer built three features into the gun specifically to meet California’s roster requirements:
- A magazine disconnect, so the gun won’t fire with the magazine removed even if a round is still chambered.
- A loaded chamber indicator — a small lever on top of the slide that rises when a round is chambered, with “LOADED WHEN UP” printed on the optic-plate cover.
- An ambidextrous manual safety that mechanically blocks the trigger. Standard P365s are commonly sold without one in other states.
The California model also ships with 10-round magazines. Any P365 magazine holding more than 10 rounds is prohibited in California no matter how you got it, so if you’re buying used or receiving the gun through a transfer, check what’s in the case.1SIG SAUER. P365-XMACRO COMP California
One important detail: only the exact SKU listed on the state’s roster is legal for retail sale. A P365 on a dealer’s shelf that doesn’t carry a California-specific SKU cannot be sold to you, even if it looks identical to one that can.
Which P365 Models Are California-Legal
Sig Sauer offers multiple California-compliant variants, not a single model. The lineup includes versions of the base P365 along with the P365-XMACRO COMP, which integrates a compensator into the slide, and other configurations.2SIG SAUER. California Compliant Each one carries its own California SKU. The XMACRO COMP, for example, is SKU 365XCA-9-COMP-MS-CA.1SIG SAUER. P365-XMACRO COMP California
MSRP for the compliant base P365 starts around $580, with street prices often closer to $500. Ask the dealer to confirm the SKU matches a current roster listing before you put money down.
How to Buy a P365 in California
Walking out with the gun takes more than picking it off the shelf. You’ll need to work through several steps:
- Get a Firearm Safety Certificate before the dealer will process anything. The test costs $25 and covers basic firearm safety and California law; the fee includes two attempts.3State of California – Department of Justice – Office of the Attorney General.

- Fill out ATF Form 4473 at the dealer, who submits your information for the background check.4Federal Bureau of Investigation. Firearms Checks (NICS)
- Pay $37.19 in state fees: a $31.19 DROS fee, a $1.00 Firearms Safety Act fee, and a $5.00 Safety and Enforcement fee.5State of California – Department of Justice – Office of the Attorney General. Frequently Asked Questions
- Wait out the mandatory 10-day waiting period, measured in 24-hour increments from the moment the dealer submits your paperwork, before the firearm can be released to you.5State of California – Department of Justice – Office of the Attorney General. Frequently Asked Questions
Plan on roughly $60 to $65 in non-negotiable government fees on top of the sticker price. Dealers add their own transfer or processing margins, so ask for the full out-the-door number before committing.
If You Want a Standard, Off-Roster P365
Maybe you want a configuration Sig didn’t submit for the roster, or you don’t want the manual safety. There are legal ways to get an off-roster P365 in California, but they’re limited and generally expensive.
Private Party Transfers
A California resident who already owns an off-roster P365 can sell it to another California resident. The transaction has to run through a licensed dealer, who handles the background check and paperwork. The dealer can charge up to $10 per firearm on top of the standard $37.19 DROS fee, and the same 10-day waiting period applies.5State of California – Department of Justice – Office of the Attorney General. Frequently Asked Questions
The real cost is in the sticker. Off-roster P365s routinely sell for well over their standard retail value because demand far outstrips supply. A pistol that retails under $600 in other states can run roughly double on the California private market.
Peace Officer Purchases and Resales
Sworn peace officers affiliated with qualifying agencies are exempt from the roster and can buy off-roster handguns for personal use.6California Legislative Information.

State Exemptions for Authorized Peace Officers This is one of the main ways off-roster handguns reach the California civilian market.
Intrafamilial Transfers
Immediate family members can transfer an off-roster P365 as a gift or through inheritance without going through a dealer, as long as the recipient reports the transfer to the DOJ within 30 days and holds a valid Firearm Safety Certificate. This exemption does not reach across state lines. If the relative lives out of state, the firearm has to ship to a California dealer and move through the standard transfer process under federal law.
Don’t Try a Straw Purchase
Asking an officer, family member, or friend to buy a specific gun on your behalf to work around the roster is a federal straw purchase. Penalties reach up to 15 years in prison and a $250,000 fine, and climb to 25 years if the weapon is later used in a felony or drug trafficking crime.8Bureau of Alcohol, Tobacco, Firearms and Explosives. Don’t Lie for the Other Guy The person who bought it faces the same penalties. This is where buyers most commonly land in serious trouble trying to shortcut the roster.
Could the Roster Be Struck Down?
California’s handgun roster has faced ongoing constitutional challenges, particularly after the Supreme Court’s 2022 decision in New York State Rifle & Pistol Association v. Bruen. A federal court ruled in 2024 that California’s roster requirements were unconstitutional, but the case is still working through the appeals process and the roster remains fully enforced while litigation is pending.
If you’re buying a P365 now, plan around the current rules. A favorable court outcome could take years, and nothing about today’s purchase process changes until it does.
