From time to time I update my personal database of my firearms and today I realized I never had entered my Model 17-4 into it. I spent about an hour researching topics before making this post. As a new member I appreciated all the information I was able to find. I have a Model 17-4 SN 25K23XX
I couldn't find a thread that listed serial number ranges but I know the -4 would put it 1977-1980 if I read things correctly. Any help narrowing that date down would be appreciated. Also would the diamond grips be the OEM grips for the revolver?
