'Microstamping' is a (mis)feature required for all semi-automatic handguns to be placed on the Roster. The law was passed in 2007, but did not take effect until May 17, 2013.

Guns on the Roster already do NOT need to be changed. So Glocks and others will not need 'microstamping'.

Guns with significant upgrades are considered to be 'new' by CADOJ; that's the issue with both Ruger and S&W. Those manufacturers have updated their guns, and choose not to keep selling the old, on-Roster versions. The changes put the guns back at the beginning, and must meet today's requirements - Loaded Chamber Indicator, Magazine Disconnect, and 'microstamping' - as well as pass the testing procedures to be placed on the Roster.

Since there is no practical implementation of 'microstamping' (and no rational manufacturer would add a 'feature' none of its customers want), S&W and Ruger are not able to meet the requirements of CA law.

Microstamping FAQ
Also, since there are no implementations to test, several other frequently asked questions are unanswerable due to lack of data:

* What parts of the gun will actually do the microstamping?
The law says
(7) Commencing January 1, 2010, for all semiautomatic pistols that
are not already listed on the roster pursuant to Section 12131, it
is not designed and equipped with a microscopic array of characters
that identify the make, model, and serial number of the pistol,
etched or otherwise imprinted in two or more places on the interior
surface or internal working parts of the pistol, ...
With no actual guns designed to comply, which parts will do the marking is not yet known, and is not specified in the law.

* Would it be legal to alter the parts that do the marking, or replace them?
With the law as it is in 2014, yes.

* What happens if a 'microstamped' case is reloaded?
Unknown, has not happened yet.

* What happens if a microstamped case is picked up in some place and dropped at the scene of a crime?
Unknown, has not happened yet; seems likely to have bad/distracting effects on the investigation of the incident.

* What about imprintability of steel case ammo vs brass? Or increased wear on internal, etched parts by steel case ammo?
Unknown, has not happened yet.

* Does 'microstamping' apply to rimfire handguns?
Yes; no exclusion in the law.

Roster FAQ

* What if a gun falls off the Roster while in my 10-day wait?
If the gun is on the DROS software 'pick list' when you purchase, and the gun is not removed 'for cause', the sale will continue.

* What about a CA PPT? (2 CA residents using a CA FFL to mediated the sale, because CA law requires it)
PPT is not, under current law, subject to the Roster.
No one will really understand politics until they understand that politicians are not trying to solve our problems. They are trying to solve their own problems - of which getting elected and re-elected are number one and number two. Whatever is number three is far behind.
- Thomas Sowell
I've been saying that for years ...

There is no value at all complaining or analyzing or reading tea leaves to decide what these bills really mean or actually do; any bill with a chance to pass will be bad for gun owners.

The details only count after the Governor signs the bills.

Gregg Easterbrook’s “Law of Doomsaying”: Predict catastrophe no later than ten years hence but no sooner than five years away — soon enough to terrify people but distant enough that they will not remember that you were wrong.
