its a slow process but it is definitely going to happen.
They really shot themselves in the foot, we had a victory nearly guaranteed in the Peruta case when the Judge- clasping at straws - ruled that CA doesn't need shall issue due to unloaded open carry was legal and that meant the right to self defense ( CA has great self defense laws ) was being upheld. Now that's its ( UOC ) is no longer legal that argument is moot.
Check out Hoffmang, Librarian, Bill Weise,Gray Peterson threads for more info but I'm sure well have CA shall issue in less then two yrs-the calguns legal brains are incredible.
