Microstamping is simply a ban on guns.
Check it out:
Smith & Wesson announced it will stop selling its handguns in California rather than manufacture them to comply with the new microstamping law. The other publicly traded firearms manufacturer in the U.S., Sturm, Ruger, also said this month that it will stop new sales to California.
The announcement late Wednesday came a week after the National Shooting Sports Foundation (NSSF), the trade association for firearms manufacturers, filed suit against California for requiring that all new semi-automatic pistols that are not already on the state’s approved gun roster have the microstamping technology.
Microstamping is a patented process that, in theory, would have a unique code on the tip of a gun’s firing pin that would engrave that information on the casing when fired.
