Well, I got the pro-package fully installed but haven't put loctite on the trigger yet.
The break is
clean on SA!!!!
The grittiness of the trigger is waaaaay reduced!!!! (And I didn't even polish)
The reset is so short.
There is virtually no over travel after reset (both SA and DA)
I can't say the DA is that much easier but it is way smoother and feels shorter.
Haven't shot yet so can't comment on it and the Kadet. I'll hopefully get some time next week.
In the mean time, here is new trigger pin retaining pin install. Open side at 12 o'clock per CGW.
