Got any friends in an adjacent state who would hold 30 rounders for you? They don't take up much space. Then you could buy the 10s for CA.
If it gets bad and Dementia Joe somehow bans 30 round mags, you could always convert the 30s, out of state, to 10s with mag blocks and some pins. (I suggest buying the mag blocks ahead of time)
The idea is that you put a spacer in the Magazine to keep the mag from accepting more than 10 rounds. Then you pin the floor plate in place to make it permanent. In actuality it is semi permanent.
With a plastic mag (Magpul) you can drill a very small hole through the lip of the floor plate and mag body on each side. Then push a thick sewing pin through the lip and mag body just far enough that the floor plate cannot be slid off the body. One on each side. Cut the pin off flush at the plastic with wire cutters.
You don't have to use sewing pins. Any stiff small diameter wire will work.
If you don't want the pins to show you can melt the plastic slightly with a soldering or wood burning iron to just cover the pins on each side with hot plastic.
This is meant to be done with Magpul 10 round blocks that convert a 30 to a 10. I think Magpul still makes these.
Here is another brand. MagazineBlocks.com. I used these several years ago and they work. They are available on Amazon too.
This will make the mags legal 10 round magazines. And it doesn't take too long.
If you ever need to open the magazine for maintenance, you cut the plastic slightly until you can pull the needle pins out with small pliers. Then you can slide the floor plate off without much damage.
OR you can push the pins into the magazine body to be retrieved upon opening the mag.
BTW - Just do a Google search for AR 15 magazines for sale. Probably the biggest is GunMagWarehouse
