owning guns in CA is perfectly legal. Depends on what county you are in whether “brandishing” can get you in trouble or not. If you are in your house you can brandish all you want, off your property you had better be in real danger before showing a weapon. BTW, I own many firearms here in the Northern part of the state.
It doesn't matter what remote CA county you're in where you think you're safe from the gun grabbers, the fact is that over here to the East across the NV border, we pity you Californians on the RKBA issue, Castle Doctrine, right to defense, 'Shall Issue' policies, identity protection, immunity from prosecution, and protection from civil suits resulting from lawful defense.
Pity, I said.
