If the Gun Laws of California are what you value above the actual place you choose to live ? .... Then by all means LEAVE !!
Lived here in California my entire life, been too and visited @ 20 of the other western west of the Mississippi states and can can tell you FIRST HAND ..... California has within it state borders more diversity of terrain, Things to do in wild places, Beach's, Mountains, Desert etc than near those other 20 western states combined !!
Yea the Gun laws are tougher, but in no way a deal breaker in living within IMO one the most beautiful and diverse states in the union.
