Because if you so much as change the finish on a pistol, it has to go through the whole DOJ approval process to get on the "safe gun" list again. I doubt the Gen4 is going to get approved in CA in any event. As of Jan 1, new guns for approval have to have a magazine safety which Glocks don't have.
Best just get the Gen3.
My condolences to the OP for having to live there.
