They weren't "theories" old chap.
Here's one of the companies that deal in it:
NanoVia also dabbles in waveguides, inkjet nozzles and other markets. One intriguing application is the ballistic NanoTag, where lasers etch a guns serial number onto its firing pin. When the gun is fired, the pin imprints that serial number onto a bullets shell casing giving police an easy way to identify what gun was used at a shooting.
Lizotte and Ohar, who say they are firearms hobbyists, add the NanoTag letters are only 20 microns tall. For just about every bullet on the market today, Ohar says, that leaves a lot of room to put information in there.
NanoVia is in a pilot program now with the California Department of Justice to test the NanoTags. Lizotte said preliminary results should be available by January.

The firing pin can be replaced or the existing one can be removed, filed off and replaced in under two minutes.

The firing pin does not strike the shell casing

The fining pin does not strike the bullet. The bullet sits in the nose of the brass and is the projectile that causes damage to the target.

People need to understand the basic fundementals of firearms and the components of a typical weapons' round.
There are four components to a cartridge.
1) Shell casing the shiny brass or nickel cylinder - that holds the following
2) Primer - ignites powder
3) Powder - the stuff that goes boom when ignited by the primer
4) Bullet - the thingy that travels down a barrel and spins due to the lands and grooves in the barrel - the bullet is the projectile.
The casing is not imprinted because the firing pin does not contact the casing. Firing pins can be replaced, or the s/n can be ground off.
People who pretend to be experts need to understand what they're taslking about, or use the correct terminology. Maybe spending 3 minutes reading a reloading guide might prevent people from embarassing themselves.
The article was written by a dim bulb who obviously does not know the components of a round.
I agree with you, most folks who have never reloaded don't know the first thing about a round.
But the point is, they do have the technology to etch on the head of a pin.
Which brings us back to my original point on that thread:
"Change the firing pin and make their good idea a bad joke."
Yup.
