I recommend that you say nothing to anyone about your firearms!
Some may be prohibited in CA and the problem is even the DOJ of CA doesn't really know what is and isn't prohibited!!!!!!!
Bolt actions are fairly safe, some shotguns are OK, watch out for the handgun thing! Almost all revolvers are OK! Magazines can be an issue!
Might wanna locate a site on the net that will tell you what is and what isn't OK and then don't trust it fully cause like I said the DOJ of CA doesn't know!!!!! Try look ups for NRA, Gun owners of America, Second Amendment Foundation, etc...... Don't use Google cause they have restricted all firearms stuff (you can still look up porn but no firearms go figure). Yahoo is still freedom based and should work.
I left the State of California (I was born there) because of this kinda stuff and I intend to stay away until they get some sense which may mean I never return.
