Was easy to install. Well made- has a super small, precision ball bearing on the end that contacts the trigger plate. Polished all around.
Weaknesses:
Not the same geometry as original. Zero instructions. Requires sear lug height adjustment. To adjust, remove bolt. Insert a 1/8" hex wrench thru the small hole in the sight rail until the wrench is seated in the lug. Rotate approx. 1/2 turn counter clockwise.
Conclusion:
Provides minimal improvement. Replaces a short, crisp trigger pull with one that's long and "mushier". May not last longer- the lug end of this replacement sear is the same as the original.
