[EDITED TO BE AS ACCURATE AS I CAN STATE MY UNDERSTANDINGS]
Generally, CA discussions should not mix up "short-barreled shotguns" ("SBS") and AOWs....
A NEW SBS is specifically not legal in CA for average citizens under CA law, even if it has a federal SBS tax stamp (ie, "paper").
A C&R shoulder-fired shotgun can apparently have the barrel shortened (and/or the entire gun shortened) to otherwise-illegal length(s) under CA law because its C&R and has a blanket exemption. I believe it still needs federal paper as a SBS.
A federally-papered AOW "shotgun" of any age is OK in CA as its exempted.
