I have a 6" silhouette model (the one with the four position front sight) 686 that's had an action job and the front of the trigger guard stippled. It is by far and away the best centerfire pistol I've ever owned or fired.
The best rimfire revolver I've ever fired was my buddy's 4" blue S&W Kit Gun. It was a sad day when his truck was broken into and that gun stolen. Close second is my 5 1/2" blue Single Six.
Its all downhill from here. Except the parts that are uphill.
