Not exactly. Maryland had ballistic 'fingerprinting' where they required a spent case from every handgun sold in Maryland. Supposedly all the fired cases would be entered into a database for matching with future crime brass.
That technology was shown to be deficient and has mostly been dropped. This is the next step, where instead of relying on the various random markings generated by firing a gun, a specific marker is used to stamp the brass.
Still a huge joke. They will have to ban all revolvers at the same time, and most handgun makers will forego the CA market rather than submit to the changes. Another back door gun ban.
