it has a target spring. I can remove the sear and blade spring and manually set the trigger and I still get that same measurement. The sear is polished to a shine. I did not mess much in the trigger surface other than a few passes. I have two sear, the original one which will give me 1.5 pounds and the side release one which will be right under 2 lbs.. I will check the 2 sears again, I might try to cut the top release sear just like the original sear is.
