Nicholas, not at this time Sir. https://yubanet.com/california/ag-becerra-defends-ca-law-that-bans-the-acquisition-possession-of-large-capacity-magazines/

your problem will be that the gun will not be on the CA DOJ approved list so the magazine size does not matter oag.ca.gov/firearms/certified-handguns/search

With limited exceptions, California law prohibits any person from manufacturing, importing into the state, keeping for sale, offering or exposing for sale, giving, lending, buying, or receiving a large capacity magazine.1 (A “large capacity magazine” is defined as any ammunition feeding device with the capacity to accept more than ten rounds, but does not include any .22 caliber tube ammunition feeding device, any feeding device that has been permanently altered so that it cannot accommodate more than ten rounds, or any tubular magazine that is contained in a lever-action firearm)
