I think it would look like a Saiga 12, only the reciever would be aluminum, embedded in plastic, and it would of course have the trigger safety, firing pin safety, and every other kind of Glock safety (inluding a safety against looking good), the magazine would be plastic and load 19 rounds, except for those states (Kali) where you're not permitted to have that much fun at once.
Springfield's Croatian partners would follow suit with a similar model for a few bucks less. It would "Out-Glock" those ducks! :barf:
