I don’t know about sillycalafornia but the Beretta Cougar came out about the time that the polymer craze started and they didn’t sell very well. I have one and I like it much better than the 92. Better balance and much easier to carry.
The Cougar came out after the Clinton craze and used a different magazine than the 92 that only held 10 rounds. I think what happened was that Beretta knew that it was a good gun and very accurate due to the rotating barrel so they started designing a new polymer gun (PX4 Storm) and had Stoger start building the Cougar (They owned Stoger at the time) who has been building it for Years.
Beretta took the same barrel design and build it in the Storm.
As far as I know none of the Beretta’s came with 15 round magazines due to the Clintion magazine band but as soon at that slyness went away the deep vertical groves were removed from the mag and that is what’s being supplied with the Stoger Cougar. I do know that Stoger does sell the 10 round magazines so as long as you only own the 10 rounder it would be the same gun as the legal Beretta.
California as I understand it semi’s are limited to ten rounds. Guns made 1994 do not have a legal limit provided the magazine was purchased before 94 or 95. It allows one more way for the Gestapo to keep certain guns out of our collections.
So removing all logic from the decision, my guess is that since the Stoger is considered a new build (after 2000) and is sold with a 15 round magazine it’s a BAD gun. But if Stoger sold the gun as a Calafornia only and just the 10 rounder’s it might be legal. What's the chance that gun companies don't want to invest the money or effort to try to match CA's ever constant changing laws?
I have the Beretta 8000 and 12 Stoger 15 round magazines, I also have the Storm 9mm carbine that takes the same magazine.
