Not sure what you are referring to. I do my own Encore trigger job. Cleaning up the trigger, sear, and hammer; along with adjusting engagement and trigger pull. The only screw adjustment is for trigger over-travel. Some frames did not come with the over travel screw, located in the trigger gaurd behind the trigger. But, I'm fairly certain these were earlier frames. I would assume the over-travel screw is on your pro-hunter.

Let me know if you have more questions.
