Hard to say based on your description it sounds like you just don't understand how a 2 Stage Trigger functions
The first stage moves to the second, there is travel, then it hits a wall of the second stage, after the second stage breaks and fires the rifle there is travel after the second stage to the back wall
So you have a lot more movement in a 2 stage trigger vs a second stage,
I tend to leave most of my AI triggers as they are out of the box, I am fine that one, the AT I tend to shoot comps with so I lowered it a little, but not a lot, I dont' really wrench on my AI triggers I tend to like them as is
