GlorifiedMailman-a few points:
1) If you are past 2000 rounds on any gun, IMO, clean it if you are carrying it.
2) A GLOCK Armorer should inspect yearly, and the recoil spring should be replaced at 5000 rounds(their recommendation if I recall correctly).
3) Good ammo and mags are part of the function equation. Put crap in gun, get crappy results.
I’ve had a Gen2 21 since the early 1990’s. Shot matches with it and carried it. I have a Gen3; not much shooting, but I wouldn’t hesitate to carry it with vetted mags and factory ammo. I have been issued a Gen4 which went through 1000 rounds at a GUNSITE class. It was field stripped mid week and cleaned, lightly lubed-no issues. I had better eyes several years ago, and could ring a popper at 50 yards about 90% of the time. A miss would be on me and my trigger work.
If your example works, drive on, reload ammo carefully and don’t worry so much about what is on the internet sometimes...
No thing made by humans is perfect, and ALL brands have an issue from time to time
