From what I understand if you grind or file a serial number off they can still look microscopically at the metaI and see the number because of impression that goes through the metal. I don’t know how deep that will go with that method.

Probably because you aren't a criminal

I believe that law enforcement would much rather prosecute one in posession of a firearm with the serial number removed, than to find the actual origin of the firearm.

Some heinous criminals punch the numbers out with a sharp punch, or sometimes they drill them out. Like you said, simply filing or grinding them off does not get the job done.

deep enough... acid etch will bring it out

Grind it off then take it to a dentist and have em X-ray it ...... shows up every time. I’v seen me do it when I was EOD ......

Steal a gun if your going to shoot some one and then bring it back to who ya stole it from. Get yer security cameras and popcorn and put it on u-tuub and get a million views.
