Pulling the trigger group apart was educational when I first installed the TTI lifter.
Lost the carrier spring washer, that made ftf and fte go from seldom to constant.
Lost the axel c-clip, but that was easily temporarily fixed with a traditional c-clip.
Installing the heavier carrier spring from Brownell's fixed a bunch of existing issues made worse by losing a washer.
Reinstalled my stock lifter and shells stopped nosing downward. Decided to go back to a Wolff factory power recoil spring. The reduced power recoil spring increased felt recoil. It actually ran a mixed tube of low recoil bird/buck/slug 100% when I was done.
Timing, it's such a misunderstood and critical operation.
I'll bend the TTi nose in increments, shooting it for feed reliability this weekend. I gotta hide in a corner with a torch and a vise. Hope no one notices when I hog out a couple holes in the shooting table
