"has a trigger variance pull of 2lb 7oz to 2lbs 9oz" That's the sort of thing that had so many people working on their triggers. I don't like them varying that much. From my years of active membership at RFC I thought every CZ rimfire owner worked on their triggers. The factory triggers I've tried were passable and certainly usable, but not clean, crisp and consistent. I bought a Brooks kit for my WMR American back when he first started selling them and it made a big difference. It was still not like a Cooper or Jewell trigger, but really nice.
