This is a picture of a no-dash Mod 60 I bought new in 1982. It was the first S&W revolver to show up in my area that didn't have a pinned barrel, yet still retained the "no-dash" designation.... It and many other S&W's of that era shipped without a pinned barrel and/or a recessed cylinder. They became known as "transitional guns" until both those features were completely phased out later...
I would guess these fine Mod 60 firearms had to be among the most carried off-duty and CCW revolvers by law enforcement officers for a couple of decades. They were in short supply to the public from their introduction for that very reason....
Just a short recalled history lesson, children...
Long live the Mod 60!!
