Just done the same mod on the trigger housing and also removed the adjusting screw whilst at it so the spring now sits down on top of the threaded brass insert that the screw resides in, trigger pull now at 3.5lbs as opposed to over 6lbs which was lightest pull setting when adjusted from standard, not polished anything as happy with result and just lubed sears and pivot point and put back together.

Had rifle from new and very happy with it apart from the heavy trigger but wantedto wait until out of warranty before modifying, was hoping to get out with it this afternoon/evening for a play ..... sat here now waiting for rain to pass
