Wouldn’t “micro” stamping be subject to quick wear from normal usage or even a quick swipe with a metal file? (Honest, it just felt a little rough when I was doing some maintenance so I fixed it)
Being the governor of California means never having to know how to pronounce the word, “Metallurgy.”
On the TV show Forensic Files....
The cops wiped a chemical solution on the area were the gun serial number was filed away....
Anyhow, they were able to retrieve the serial number....
That’s all I know about this.
A little valve lapping compound on the microstamp and good by microstamp! Or you can just buy a new part to replace the one with the stamp.
