I just picked up my first model 686 to go with my 66 no dash and 66-2. I really like the feel of this gun. BTW, a 4 incher. I have 2 questions; it appears to be an early one, no dash, serial ABW6566; anyone know the year? Also it has black rubber grips that look like Pachmyers, but there is no emblem of any kind; are these original? Can't wait to shoot it.
