The Glock is simple enough I'd try replacing stuff. Extractor, striker safety and spring etc.
Problem is if it only acts up once in a couple hundred it will take alot of shooting to determine if you really got it.
We had an officer who couldn't get through a mag without an issue. Instructors brought it to me and told me to replace everything.
I refused since I would never know which part was causing the issue. We'll do one piece at a time.
Turns out there was nothing wrong with the gun. I went to the range myself and there were several others there. I shot it fast, slow, I purposely limp wristed it, shot weak handed, I even shot the thing upside down and it never failed.
I gave it to the guys up there and said everybody shoot this thing, no failures.
Turns out it was him. I don't know now what they did to change his grip but he's had now issues since.
Still a mystery to me.
I agree they are ugly, we modified the grips on ours so the angle is better, still not perfect but they should run.
It could be you just don't like it and you'd rather leave it in the drawer or safe and that's perfectly fine too.
I got no issue with that at all.
