I checked all my K frame Targets the rear of the sight is smooth.
I think it is only the N frame that has the grooves.

Yes, I agree and I believe it coincides with the introduction of the RMs since most or all of those that I've seen have the grooved rear sight. But then again the sight I have off the gun is only a 4 digit # which has to be an early N frame unless it's not a complete #. However there's lotsa room for the entire # on the underside of the sight and I think I remember complete serial #'s on the rear sights.
