I installed the basic polymer trigger and sear spring in my 9c.
FWIW, it got rid of the finger pounding experienced with the stock unit but it feels a bit spongier now.
I had to open the loop to get sear release but was not real precise about it.
Question is, does "excess" opening cause any probs?

You need to be more precise on what parts you replace and what parts you used.
The trigger bar needs to be adjusted in small increments until you get sear reset, there is a very well explained video on youtube, or you can contact apex customer service.
Hard to be more precise - I installed the 2 parts I mentioned, replacing the 2 stock parts, and sear release was the issue, not reset.
Anyhoo, I called Apex, spoke to Jim (super friendly, helpful) who said .003"-.005" per trial is suggested.
Too much (unspecified) opening can cause several possible problems so "just enough" is best.

Take a feeler gauge to the opening of the loop, what does it read?
It will vary from gun to gun but I had to set my loop at .019" to get reliable sear release.
FWIW to anyone doing this install, my sear block doesn't slip in and out easily with the trigger assy in place as in the video Shield & LG reference - I have to torque the trigger bar up and wrestle the block in and out.
Also unlike in the video, my sear block pin has to be fully in place to check release - partial pin install may release the sear yet still not release when it's fully inserted.
YMMV.

0.019" doesn't sound like much. 0.021-0.24" have been measured in unmodified trigger bars, i have gone to 0.028 and 0.016 but 0.028 increased overtravel too much. reset lengthened as well.
