I have a new m27 s&w that I've put about 750 rounds through. The trigger is a little heavy but it's fairly smooth and I can live with that. The single action is pretty good. The problem is with the da trigger. After the action is staged, the last 1/8" or so is really rough ad gritty feeling. I've had the sideplate off twice to clean and re-oil, but it hasn't helped. What is it that I would need to do to smooth up that last 1/8" or so of the trigger? Thanks.
