Ive been shooting the same 17 here all along while this thread has been going on, and as I mentioned back in the begining of it, its been running fine, except for the occasional head bop with my reloads. Factory has, and still seems to run fine.
About two weeks ago, it was like a switch was thrown, and ejection became very erratic and I started to get hit in the head and upper body every three or four rounds. I thought maybe it was time for a recoil spring swap, since its been about 5-6000 rounds since the last one was changed out, but that didnt seem to do any good. I then detail stripped the slide and gave everything a good cleaning last week. The extractor, as well as most of the rest was pretty loaded up with crap.
Took it out today, and the first round nailed me in the head, and out of the next 299 rounds, only a couple more got me or even came close, and it seems to be back on track.
Now my question is in regards to the "dipped" extractors and why they are dipped. Is that dip there to allow crap and crud to more easily clear itself, allowing the extractor to continue to move freely? Seems once I got that crap out of there, it straightened right up and started to run right.
Im starting to wonder if this isnt all just lack of hygiene.
Not in my case I've been meticulously cleaning between outings to include detail strip of the slide. In contrast, ToddG over at pistol training.com has been running a gen 4 g17 in the tens of thousands of rounds and has only cleaned it a couple times.
It seems that if you have one buggered up from the start it stays buggered up despite trips to Glock or part swaps. Mine has been through four extractors now and it got better but still does it. I'm starting to doubt it's the extractors or ejector being the problem in gen 3s with a problem from day one.
Others though seem good from the start but develop a problem after the first 500 or so rounds. That might just be a parts issue for the ones that started off okay then deterorated in consistency. Mine and some other people have ones that never ran right from go. IMHO. I think if you have one of those chance to fix gets slimmer.
I know the frame from my "bad" one is okay. I can take the slide from my older g17 and put it on the new frame and no BTF. If I take the slide from the bad one and put on the old frame it does the same BTF ejection. I think there is something hincky in the slide or the channel cut for the extractor. Looking at what others have tried even putting all the guts from a known good one into a problem pistol doesn't do much.
