I do have the Henning flat trigger kit. The new sear at 1st with no filing at all would not reset the trigger at all with the slide on, After filing some the trigger would reset on slide rack, but at the rage it would not reset after a shot. I took a sanding stone to it and did a little more, and this past weekend I ran 150 rounds with zero issues. Now I just want to get the safety working, if possible without buying a new safety lever.
