I just don't get it... how in the world does Jerry Miculek manage to put up with his inferior MIM equipped S&W revolvers all of these years and yet still do the things that he does while shooting them DA?
A miracle I tell you... or the devils work
To the OP's question... I have owned a 686 no-dash, a -1 and -3... they've all worked fine for me, but I do have a preference for the -3... only because of it's 2.5 inch barrel.
