Catch 22. - Residents of Calif are felons if they try to opt out.
Coming soon to a State near you.
And the band plays on....
California has so many anti-gun laws that you can become a felon without even trying. Just buy a handgun magazine and appropriate ammo for the mag. Put just 1 round into the magazine and step onto a public sidewalk or street. Bingo! You are now a felon. The magazine is part of a gun, thus loading it makes puts you in possession of a "loaded gun". If you possess a loaded gun on a public street and you don't have that gun registered to you on a Form 4473, you are have committed a felony under California law.
I have a nice collection of guns...all relocated to my home in Idaho. I'm finished with California.
