Def not the sear. Everything is well lubed and the grittyness comes during takeup before the trigger pressure ever hits the sear. I’ve polished up contact areas between the trigger bar and the fcu and that helped a little. You can feel the resistance pick up after pretravel and it feels a bit gritty, then it hits the sear. Theres a little bit of travel where you can feel the sear sliding down the striker engagement then it breaks fairly crisply.
(Havent actually recieved the pelt2 yet, should be here friday)
