I have a 4" stainless DAO model. This is the factory double-action only model with bobbed hammer. The 686 is a great gun, but not more accurate than the Ruger, and you can use the money you saved on the Ruger to have the trigger smoothed up, if needed, if you can't do it yourself.
I like mine because I believe double-action revolvers should be fired in double-action, and with this one, there is no SA to fall back on. Even so, I shoot this DA better than I shoot my 6" Dan Wesson in SA mode...about 2-1/2" at 25 yards, from a rest.
