I've got the Triggertech FX-9 Adjustable in mine and I love it. It's a huge improvement over the gritty stock trigger group. I have it set somewhere in the low-middle in terms of pull weight and it's so crisp with very tiny take-up and such a short reset that I can hardly believe it. No issues with light primer strikes so far, and have run 115, 124 and 147 gr. of various factory (Speer, Blazer, Winchester white box, PMC Bronze) and reloaded types. It's one of the few components that instantly made this thing more fun. The fit is great, the install was easy and feels really solid with the additional pins driving down and pressing off the bottom of the receiver against the receiver anti-walk pins. No rattle, no wobble, and no motion besides pew pew pew!
