Love my 63 4" pinned barrel (1981). I have had it for about 5 years. Found some NOS square butt J frame target grips on E-Bay. (See H Richard Post above). Fun to shoot and always goes to the range with the bigger boys.

The few I have seen at gun shows in our area are priced around $900. Glad I got mine when I did. If you find one at a good price - jump on it.
