I just purchased my second smith and wesson. I picked up a 686 talo with three inch barrel. Only one issue, something is a miss with the trigger. DA is fine. SA when the hammer is pulled back sometimes it randomly goes foward on its own, also if it is back and you push ever so slightly on the hammer it goes foward. My thoughts are the mainspring and or the trigger spring. Maybe a botched job by the previous owner. Considering buying a wolf spring kit but would be fine with a factory kit as well.
