Don't count on that. The DOJ approvals have expiration dates. Even if a Gen3 were resubmitted at that point it would fail since it too Would have to meet the then current rules to be recertified. Given them racheting up the requirements and the expiration dates, eventually very few handguns will qualify to be sold in CA, which is the whole idea.
