BudsGunShop.com - Is this California legal? I am getting mixed nswer

Yes CA legal. Because it is a pump action, it does not fall into any of the banned categories.
"Prohibited:
Shotguns
✘ Shotguns with revolving cylinders (e.g. Franchi SPAS 12, USAS-12, Striker-12, or Street sweeper).
✘ Semi-automatic shotgun that has both a folding/telescoping stock ​and ​a pistol grip, thumbhole stock, or vertical handgrip. ✘ Semi-automatic shotgun that has the ability to accept any detachable magazine. ✘ Shotguns with tubular magazines in which the ​combined​ammunition capacity ​exceeds 10 rounds AND can be fired by the shooter without either manipulating the magazine selector switch (such as the Standard Manufacturing DP-12), OR that can be fired using a selector switch that allows the shooter to alternatingly use ammunition from more than one tubular magazine without having to manually switch the magazine feeding process (such as the UTAS UTS-15), ​are prohibited​"
