WOW! I just found this post and I need to read the entire thread and reply to it. The information posted by Sal and the others weighing in is nothing short of amazing. I had the pleasure of meeting Richard McMillan in Reno and found him to be a true authority on the model 39. I hope to meet Kevin Williams some day and pick his brain as well. Sal gives many accolades to others such as Roy, Richard and Kevin and they are well deserved however Sal has shown time and time again that he is an S&W authority in his own right. I own many variations of the model 39 and have collected them for over 25 years yet each time I talk to or read a post by our members, I learn something new.
