Parashooter,
Take a look at reply#6 Butlersrangers reposted one of my photos with a box drawn around the trigger where it will contact the trigger guard. On the front of the trigger there is a small pad that limits the sear engagement and maybe a little extra thickness at that point. I intend to take that pad off as well as a little extra on that front surface. I too like the humps of the first stage and do not intend to touch them. :-)
