Heard back from Rep Bert Kobayashi. Here's his take:
--snip--
Thanks for your email about SB219, which I have just glanced at; a multi-page bill, not easy digested quickly.
I'm not on Judiciary committee which will approve or not approve this bill, so likely will not see this bill until it comes to the floor, meaning the full House. By that time, the votes are relatively clearly set; i.e., most committee chairs will not bring a bill to the floor without votes to pass. The House Judiciary chair did take an informal poll on a gun control bill several weeks ago but I do not know the results of the poll.
Likely, there will be some sort of gun control bill passed, given public input and sentiment to date.
There is likely to be a grandfather clause in the bill, perhaps in addition to section 3 of the bill, which it talks about "mature" rights....but this was from my quick look.
