California law classifies muzzleloaders(black powder guns) as antiques, even the reproductions.
So, if you live in Calif., you can defend yourself with a muzzleloader and avoid all the laws that restrict modern firearms. At close range, they are just as effective as modern guns, and much
less expensive. It takes a little more work to load them, but the difference is worth it.
You can get a blackpowder revolver for $150. A modern gun will cost you $400.
