There is no such thing as a Shield or any other handgun with microstamping. Not sure where you guys are getting this? There has not been a single gun ever sold with microstamping. It is a totally non-workable, impractical technology that other than experiments in a development lab, doesn't exist. Our anti-gun Attorney General made an arbitrary and capricious ruling that no new handgun could be added to the California Not Unsafe Handgun Roster without microstamping. Since none of the manufacturers will ever add microstamping since it is basically science fiction, the handgun roster has turned into a defacto gun ban on new handguns in California. Point, tyrants. We have a court case in progress, called Pena vs. Cid that is challenging this. The case will go to the 9th and probably the SCOTUS as the roster is totally illegal and unconstitutional.
