I used two S&W 686 revolvers when I shot PPC. A 4" with black sights and a 6" with black Patridge sights. The 6" eventually replaced my Davis custom revolver and the 4" rode in my duty holster.
The model 60 is a small revolver and built more for concealment than for shooting. Not to say it can't be shot, my M36 certainly helped me win a couple of off duty matches but I would never have considered it for my main match revolver.
As for the ported 686 (or any ported firearm), I personally have no use for them. Even with magnum ammo the 686 is a pussycat to shoot.
Glad to see there is still interest in the Distinguished Revolver Class.
Good Luck
