I have never seen one that did. You can get a scribbing pin and do it yourself and or take it to a engraver and let them do it for you. Once you do so take pic's of the trigger group and save them. If the gun is stolen then you have pic's to ID the gun and or trigger group. I had my trigger group stolen one time and now I have marked the hell out of the trigger group to ID it. Pic's have also been taken.
