I installed the SSS trigger last year. Since then it felt like the pull was getting heavier. Recently I picked up a trigger gauge and sure enough.. the pull weight was at 4.5 lbs.

I got it adjusted down to a 1.5 lbs. After several dry fire attempts it stayed at 1.5lbs. This weekend i put 40 rounds through that rifle.. and sure enough the trigger felt like it was getting heavier. Measured when I got home and its back at 4.5 lbs. It's not consistent either. A couple of dry fires come in at 2.5 lbs but most are over 4.

Talk about frustrating.. does anyone have any suggestions?

Thanks
