Regardless of which combo of parts, the last thing you need to do after all the fitting is put dye on the sear, and cycle the hammer 15-20 times. Take it apart, and confirm both hooks are grabbing the sear evenly. Saw it again today, beautiful crisp sub 2Lbs trigger, only using one side of the sear. Back in the jig 3 times to get it even. As is, it was beautiful, but would not have lasted. Super happy with end result, good luck.
