Good luck on your quest! I suppose the NRA or some other pro group might be willing to help, or even the local California organizations. Here in my area the only one is about an hours drive in Fallon, called Stillwater Firearms Association. I know they'd love to have a lawyer fighting with them (they already have one or two plus the Deputy DA).
Maybe someday you'll be able to get California to acknowledge reciprocity with sister states, and I won't have to disarm every time I come up to grandpa's house.
