I noticed that there is a ridge on the striker spring guide rod where the trigger weight sits. Why is it necessary to have that ridge there? As the striker being compressed the trigger weight needs to slide down on the guide rod. It seems to me that the ridge might cause initial resistence where the trigger weight might get caught on there and therefore inconsistent trigger pull. I am so tempted to grind away the ridge and make the guide rod smooth. Of course before I do that I want to check with you guys who know the Steyr better.
