I had a beautiful 686 No Dash 4". Sold it to buy something else and I do miss it. I've owned a GP100 and it was great. Sold that too. I now have a Police Service Six and I love it. Size of a K frame with the strength of an L.

If I was looking for either revolver, I would get a used 686 or a used GP. I just can't get past the lock and black MIM parts on new S&W revolvers, and the new GP's come with those hideous Hogue rubber grips, so replacing them is gonna cost another 100 bucks or so. So in the end, whichever used 686 or GP was in better shape would get the nod. I am sure the used Ruger would be cheaper, too.
