I don't know if I wouldn't take them up on this, Sam. Who knows what might happen down the road and have some dunderheaded fool try to charge you for defacing a serial number or some such foolishness like that because S&W put 2 different serials on your gun. Of course the one on the butt is the official number but I could foresee some kind of problem potentially because the serial in the yoke cut not matching the official serial number.
