If something like this was implemented, I would be interested in what the workaround is and how soon it comes out. We're real good at that stuff in CA. We have the "bullet button" for ARs, and though we have our stupid "safe handgun" list that prohibits a whole bunch of pistols, we can pretty much get any of them legally using what's called the Single Shot Exemption (SSE). The way it works is:
Choose the evil handgun you want.
Send it to an FFL that does the SSE conversion (there are a half dozen or so)
That FFL will remove your barrel and replace it with a 6" or greater length barrel
That FFL will replace the magazine that came with your pistol with a blocked mag that only accepts one round
That FFL will then ship the pistol in that configuration, with your original parts, to your local FFL
After your 10 day wait, you pick up your single shot pistol with the long ass barrel and take it home
At home, you remove the 6" barrel and blocked mag, replace with the originals, and send the borrowed barrel and mag back to the SSE FFL
You now have a CA legal pistol not on the "safe handgun" list
It costs around $150 on top of whatever the pistol cost, but the point is, whatever lame ass restrictions they pass, smart people find a workaround. I don't want to see any restrictions, but the antis usually get outsmarted on any they pass.
