Well, I thought this would be a FUN project. So far it has not been. This is my first one. Before anyone responds, I would like you to know I've built about a dozen AR's and do action jobs on my Ruger revolvers with stones, not a big Dremel fan for most things. Anyway, this is my first Glock build, but it's not my first gunsmithing outing by far. But it has been the most frustrating I've ever done.
Details:
Just so you know, I've hit the usual culprits, not adequately clearing the recoil spring channel, and not having the spring for the takedown latch flush with the bottom of the recoil spring channel. I've also rounded and polished the firing pin safety plunger and stoned the mating surface on the trigger bar that interfaces with it. I've cycled the slide a couple hundred times by hand and it works flawlessly when not actually loading a round. I've used both a Glock 19 magazine and a P-Mag in my range testing, and both feed reliably, and both lock the slide back properly when empty.
So, off to the range today with 200 rounds, thinking I might have some breakin issues my first 50 rounds, but expecting pretty clear sailing after that. No such luck. For this 200-round range test session, here were my issues.
Issues:
Soooooo frustrating. I was so irritated on the way home, I thought of handing it over to a local gunsmith, but, my pride kept me from driving right over there with it, so went home and did a little Internet sleuthing. What I've discovered is that these builds typically are tight but break in quite nicely most of the time, and 200 rounds usually does it.
I also found that some have had issues with reliable ejection and have suggested the APEX TACTICAL SPECIALTIES INC - FAILURE RESISTANT EXTRACTOR FOR GLOCK, at $56, and it gets high ratings. I'd like to know if anyone here has used one before I go on a parts buying spree.
At least one YouTuber had consistent FTRB issues much like mine, and said replacing the stock (I think) 18# recoil spring with a 20# recoil spring cleared up the issue for him completely. I'll likely get the steel recoil spring guide if I replace the spring, as I think it's just a good idea on principle, although Glock is fine with a polymer guide.
I am delighted with the pistol's feel, its shootability, and accuracy so far, but I'd love it a lot more if the darn thing was reliable! Here is a shot of the polished striker safety plunger and the trigger bar that I polished.

And here is some light stoning I did before the range trip to ease the front and rear edge of the locking block on the barrel. I did a little light stoning on the inside of the ejection port with that long square stone, as well, thinking it would help the last bit of going into battery. But the range trip was still awful.

Thoughts on a fix? Take it to a smith? Toss it in the bin and chalk it up to experience? I'm open to any and all thoughts. Oh, ammo was IMI 115 grain HP. I used Tetra gun grease on the rails expecting it to help with breaking in.

Issues:
- The slide will not go into battery that last 1/16th inch on 85% of my shots. About 15% it will and I can take a second shot, but the other 85% I have to smack the rear of the slide to send it all the way home. There was no improvement at all as round count rose.
- About once per magazine it will fail to eject and the case is stuck backwards in the ejection port, typically.
- Ejected brass is everywhere, hits me in the head, flies behind me, off to the side, very inconsistent ejection.
- For some odd reason, the trigger pin walks out of the frame to the right side as I shoot. I had to pound it back flush three times during the 200 rounds.
