I too am in California. I got my Saiga-12 pre-converted and CA legal from Atlantic Firearms. The laws here are weird, confusing, and not particularly intuitive. I found this website very helpful (http://gunwiki.net/Gunwiki/LegalCalifornia). As you probably already know, no folding stock at all and some sort of bullet button will probably be necessary unless you don't want anything fun on it. You can find 10-round AGP mags right here on Saiga-12.com for a steal (especially if you buy 4+). I use them and have been nothing but happy with them.
