The spring is noticeably stronger and the trigger will pull back to the full retract when released. For anyone else if your trigger does not retract when you pull it to the end of the first stage then release, you may have a modified/wrong spring or a serious lack of lube with maybe gunk holding things up.
Did clean up the sides of the trigger channel per BR suggestions. Looking with the repaired bore scope from the sides there was no evidence of rubbing but the sides are now smoother and overflow accuglass has been removed. At least I will never have to think about that one again.
Still planning to take the front step off the trigger to lengthen first stage travel. No down side to that plus a little extra sear engaged initially is a good thing. Several more small things to address.
