Here is a sticky from Calguns forum that was posted by Librarian.
The wiki has a long article: Large-capacity magazine restrictions and there is a long thread here at Calguns but for those people who find themselves unable to click on a link:
California restricts certain things about magazines greater than 10 rounds; it has created a silly legal name for them - "large-capacity magazines" - and says we 'regular people' cannot import, sell or manufacture them. ("Dealer" FFLs may get licenses from DOJ for these activities; curio and relic licensees cannot.) The restriction applies to both centerfire and rimfire weapons.
It is perfectly legal - no restrictions at all in the Penal Code - to own and possess and use those "large-capacity magazines" in any gun*(see footnote), at any time, under any circumstances where it is legal to use a gun. Ownership, possession and use of "large-capacity magazines" are not crimes in PC; there is no section under which you could be charged.
Those who own "large-capacity magazines" are not required to keep records or receipts, and not required to explain how they got them.
The age of the magazine and the age of the gun mean nothing. The critical item is possession of the magazine(s) in California before January 1, 2000.
Yes, you can go out of state and buy magazines of any capacity - but you may not bring "large-capacity magazines" back to CA as complete magazines - that would be importing and that can be charged as a felony. 'Importing' ALSO applies to moving here or visiting here.
Yes, you can buy part kits to repair your existing magazines - but you cannot assemble them into complete "large-capacity magazines" inside CA - that would be manufacturing and that can be charged as a felony.
Yes, you can take one of those kits and create a 10-round magazine from the parts and some method of blocking the capacity; one example here.
You can have "large-capacity magazines"; no one may give them or sell them to you in California, and you may not give or sell them to anyone else in California. This includes sales from LEO and intrafamilial transfers - that would be included in selling and that can be charged as a felony.
There is no such thing as a "pre-ban" or "post-ban" "large-capacity magazine", and it doesn't matter. Markings on magazines have no legal meaning.
If you think your legal question has not been answered, follow the links at the top of this post and read the articles, then re-read items (2) and (3) above several times. Other questions are addressed below.
* Note: it is not a part of the "large-capacity magazine" law, but part of the 'assault weapon' law that says a semiautomatic, centerfire rifle with a fixed magazine that holds more than 10 rounds is an 'assault weapon'.
That means that
if your otherwise legal semiautomatic, centerfire rifle has a magazine lock, such as a 'bullet button',
and you use a "large-capacity magazine" in that weapon, (which, because of the magazine lock is effectively a fixed magazine rifle)
then you will have manufactured an 'assault weapon'.
That's a felony. Don't do that.
NOTE: A Registered Assault Weapon (RAW) is already an 'assault weapon', and not included in this problem. If you have a RAW, use any magazine you legally own.

Political and Meta-legal items
No, there is no 'expiration date' or 'sunset' on the magazine law.
No, there is no possibility the law will be repealed with the Legislature we have in 2011.
No, there is no current lawsuit in place or planned on the topic - mostly because gun rights litigators in CA have higher priorities.
Yes, something is being done - but you must exercise a rare quality - patience! Look for a new thread in the 2nd Amendment Forum from member hoffmang - Gene Hoffman.
