Great trigger if u know what you're doing - Powder River Precision Springfield Echelon Trigger Kit

The install is difficult and the install video is terrible but with some patience and critical thought, you can get it installed. One issue was the trigger safety would catch like it supposed to but a little too much. A simple Dremel job to where it was catching fixed that issue. There is almost zero pre travel which takes some getting used to but the break is 3.5lbs and pretty clean. The reset is light.
