Cleaning and moving guns and ammo.Came across this 19-4 I have not seen for a while and gave it a scrubbing down. Got the grips off...and it appears to have the serial number stamped on the RH grip. Factory? Not that it's a "collectible" as the nickel finish has a couple of grey spots here and there, but otherwise it is just a well kept shooter. Just wondering if S&W did box these up with factory Combats if someone ordered one?
