These CA laws are basically an end-a-round the Constitution in an attempt to practically ban firearms without explicitly doing so.
It's pretty clear to most people, that the intention of the micro-stamping requirement was to prevent the sale of any new model firearms in the California market. Its basically a back-door ban. They're hoping that over time (make no mistake, they're playing the long game here) as manufacturers develop new models, that the older ones will be discontinued and thus disappear from the market. Of course, criminals will get their guns somewhere else...
The same will be the case for the new ammo laws and tax (mark my words). All California legislators have to do, is increase the ammo tax to prohibitive levels or just make sure the background checks can't be done in a timely manner to effectively make any new ammunition impossible to get legally. Of course, criminals will get their ammo somewhere else...
