So I removed the disco to check behavior without it.
I still experienced drag on the slide.
So started messing with the trigger bar support spring and that seems to have alleviated the problem. But the trigger bar is definitely not the best. One side has a channel with very little wall on one side..
I polished the wing of the disco and it fixed the issues with the hammer not falling.
At the moment I am at 7 pounds 6 ounce DA and 2 pounds 0 ounce SA.
The SA is fine. The DA is not.
I may experiment with trying to cut the channel deeper in the trigger bar to see if I can make sure it is consistent.
