I bought a custom shop M45 A1 in 2014 ( about ). I put it in the safe and only occasionally shot a box of hardball thru it. Saving it for I don't know what. I had a reverse shoulder replacement and decided to seek some training. I am 72 and have no children. I could give a f*** about the gun when I am dead, so I decided to train with it. I noticed the serial # is inked on the cerakote . what happens the serial # if I have the gun refinished?
