The legislation probably has a provision that make it an offense to possess a gun which does not have an operational micro-stamping ability. This then turns into a way to convict a legal gun owner who defended himself with a gun whose microstamping had worn away.
Yep, just another way to hassle legal gun owners and manufacturers. Criminals won’t be affected one bit.
I hope the idiot company that is pushing this micro-stamping idea on state governments loses every cent they have.
