I have one (of many rifles) and like it. I gotta say though, changing from light finger pressure mode to "swing" mode is a challenge for anyone. I like two stages for moving, single stages for stationary. That said it's adjustable. Which helps tremendously.
I was reading something David Tubb wrote, and I may have misunderstood it, about taking out the backstop of a two stage. So,I took all of the backstop out of the trigger. Meaning, it swings well past the release point. On a fast pull of the trigger then, there is nothing to jerk the rifle as you move through the trigger pull. My K-31 is like that along with a couple other military two stage triggers. They are not adjustable.
