So Russian American Armory Saigas are legal?
I totally want a shotgun!!!!!
Yes.
If you are talking about center-fire semi-auto rifles, check out the CA AW ID Flowchart at
http://www.calguns.net/calgunforum/index.php. You'll either need a "non-detachable" magazine (10 rounds max) or a "Monsterman/U15" feature-less build. See the link for more info. With AR's the consensus seems to be use Bullet Buttons. For AK's, people seem to use RADLOCKS.
If you are talking about RAA Saiga-12 Shotguns, they are available as well. They MUST have a "non-detachable" magazine. There are several vendors that sell them with just the magazine locking method or converted to pistol grip, sights, etc by installing enough US-made parts to satisfy the the Federal 922 requirements. In Nor Cal (PRK Arms, Bullseye). Not sure about So Cal. Cold War Shooters? Just search for Henderson, Fedup and AlohaRover on Calguns.
http://www.calguns.net/calgunforum/showthread.php?t=141543. Just know they are EXPENSIVE.
Also check out forum.saiga-12.com and dinzagarms.com for good 922r compliance info, conversion info, and conversion parts.
A semi-automatic shotgun that has the ability to accept a detachable magazine is an "assault weapon" in California.
Saiga shotguns sold legally in California have been modified to require a "tool" to detach the magazine.
In addition to complying with California's assault weapons laws, you also have to comply with Federal law (922r) related to the importation of foreign "sporting" firearms. If you change out enough foreign parts with US made parts, you can use 10 round magazines in CA. See the 922r info on the sites above for more info.
Just remember you have to comply with both 922r and California's assault weapon laws.
In the case of a Saiga shotgun:
You can't have
(6) A semiautomatic shotgun that has BOTH of the following:
(A) A folding or telescoping stock.
(B) A pistol grip that protrudes conspicuously beneath the action of the weapon, thumbhole stock, or vertical handgrip.
(7) A semiautomatic shotgun that has the ability to accept a detachable magazine.
