I’d remove the stamp.
It amounts to a registry.
It amounts to a registry
Let's say that some gun maker comes out with a new handgun design that you want to buy. The problem is not the microstamp, but the fact that you won't be able to find that new handgun to buy in California in the first place. The manufacturer isn't going to produce special, California-only versions of their new gun. And since the microstamping tooling will be prohibitively expensive, they certainly won't add it to all of their guns by default. They will, instead, make guns for every State but California. They will just right off this market. And since all of their competitors will do the same, this de facto boycot won't hurt their bottom line.
And that is the real point of this law: To make new hanguns illegal in California.
