I think the mag restriction only applies to weapons made after a certain date, other wise they would have had to grandfather the law and I believe that is illegal. It wouldn’t hurt for MistrX to check on line to see if this is the case or not.
The mag restrictions were passed back in the early 90s. It doesn’t matter when they were made, it’s when you owned them. If you owned them before they passed the law, they are grandfathered in. If you acquired them after that they are illegal. In this case it would be illegal.
That's incorrect. The only way a mag over 10 rounds can be in the state (barring purchase by a LEO, etc) is if the owner can prove he had it before they were outlawed. If a private citizen wants such a mag, he must disassemble it and classify it as parts. Kommiefornia won't allow 11+ round mags, but they'll allow all the parts for 11+ round mags. Go figure.
