This is incorrect. Attached is the penal code defining “loaded”
12031. (a) (1) A person is guilty of carrying a loaded firearm when he or she carries a loaded firearm on his or her person or in a vehicle while in any public place or on any public street in an incorporated city or in any public place or on any public street in a prohibited area of unincorporated territory. [Since this post concentrates on loaded, other parts of 12031 are omitted, including the definitions of other terms in (a)(1).](g) A firearm shall be deemed to be loaded for the purposes of this section when there is an unexpended cartridge or shell, consisting of a case that holds a charge of powder and a bullet or shot, in, or attached in any manner to, the firearm, including, but not limited to, in the firing chamber, magazine, or clip thereof attached to the firearm; except that a muzzle-loader firearm shall be deemed to be loaded when it is capped or primed and has a powder charge and ball or shot in the barrel or cylinder.
