I took it down and everything looked OK? Maybe I'm missing something...
This might sound weird, but...did you check to make sure the safety plunger spring is oriented properly underneath the plunger? I had battery issues with a G17 that ended up being a safety plunger spring that had bound up, which was preventing the trigger bar "fin" from smoothly passing over and depressing the plunger. So when I would hold the trigger down and the spent case would eject, the slide wouldn't go fully back into battery until I released the trigger, and even then it didn't always have enough energy to finish that last 5-10% of travel, especially while trying to feed a live round into the chamber. Getting that spring properly re-installed was all it took to get that gun running with no failure-to-fire or failure-to-feed. Not saying that's your issue, but it's worth popping it out to take a look and make sure it's sitting correctly under the plunger.
Shoutout to the Cerakote King of Tacoma for helping figure that issue out!
