Niether here nor there, but in California where the gun laws are at their craziest IIRC...
As far as travelling, they want unloaded handguns in a locked container within the trunk or other inaccessible location. Outside the vehicle open carry of an unloaded (empty chambers, no magazines) handgun is allowed, while a loaded handgun may be carried by a sportsman actively engaged in fishing or hunting,
or while going to and/or coming back from fishing or hunting.
