Thanks for the assistance. I downloaded the manual
S&W_Metal_Frame_Autos_Manual_05_30_11.pdf and it appears to be what I need. Hopefully I will get sometime this weekend to try to field strip it. If that works out I really need to schedule a trip to the range. Haven't been out shooting since I left Alaska and I don't want to say how long ago that was.

Actually the smartest thing may be to take a gun class first to refresh myself.
