3. Notes/comments regarding your situation and your thoughts on this issue.
Just bought it on Sunday and it has a test fire date of 9/12/2011. I had read about the ejection issues many are/were experiencing w/ earlier run Gen 4 9mms in research prior to the purchase but unfortunately didn't come across the cutoff dates and/or specific part numbers to check for. It came w/ the new 042 RSA but the ejector is the 336 model.
I've put 100 rounds of Federal 115gr and 200 Winchester 115gr target ammo through it so far and have had a total of 5 FTFs and somewhere in the neighborhood of 20 FTEs (some vertical, most backwards half in the breech). The majority of ejected casings have noticable scoring/scuff marks on one side of them, I'm assuming from the ejector? I've had somewhere in the neighborhood of 1 in 4 casings that are successfully ejected hit me in the face/forehead and another 1/4 of them go over my head. Seems like none of the ejections wind up any more to the side than say 5 o'clock.
I called Glock today and they said I should take it to a certified armorer and have them replace the ejector free of charge. When I asked if I might need a different extractor as well they said that this was internet misinformation due to ejector and extractor sounding the same.
The good news is that the store I bought it from has Glock armorers on staff and is ~15 minutes away from my work or house. The bad news is that they kept insisting that the failures and BTFs were solely the result of my lack of technique. I freely admit to having no technique, but in the 500 rounds I put through 5 different rental pistols preceding my purchase (including a Gen 3 17) I didn't encounter a single failure or casing hitting me using equivalent ammo and technique. Gonna swing by there tomorrow and see how it goes.
I am just about a total noob so my input probably isn't worth a lot, but so far my experience w/ this gun is certainly counter to what I was led to expect from a Glock (simple, rock solid, and trouble free right out of the box). When it feeds/ejects correctly, I like the way it shoots and I feel pretty comfortable with it, but if the new ejector doesn't fix things I think I might look into cutting my losses and try a PPQ or a P30 v3 depending on how much I could recoup. Worst case, I've at least gained a bit of experience and confidence in dealing w/ misfeeds/jams.
Update: Fed it 200 more rounds of WWB last night, 2 more FTEs and a bunch more wacky ejections. New 30274 ejector on the way to the shop.
Update 2: Went to the gun show this weekend and got the whole trigger assembly swapped w/ a new 30274 ejector and picked up some 124 gr ammo. Put 100 rounds of UMC 124gr FMJ and 68 Federal AE 124gr FMJ through it w/o a single stove pipe and only a couple of BTFs even when I wound up limp wristing a few working on slowing down the trigger squeeze. Still need to try it w/ some 115gr and see if it's the new ejector or stronger ammo that's improved things for me. I'm going to be kinda bummed if I can't feed it 115 gr ammo for plinking like every other pistol I've tried so far but what you gonna do?
Update 3: Put another 150 of UMC 124gr, 30 Federal AE 124gr and 50 Magtech 115gr through my 17 yesterday. Had maybe 2 casings off the bill of the cap, 1 over my head, everything else was ejected strong to the right. No malfunctions even w/ the 115gr so I'm feeling the replacement ejector seems to have fixed my issue
Update 4: Up to ~1500 total round count and I'm really liking my G17 Gen 4 now. I'm still getting the occasional 6 o'clock ejection (maybe 1 or 2 per 200 rounds) w/ basically any ammo I feed it, but I can certainly live w/ that. Still not a single FTE/stovepipe since swapping the trigger assembly/ejector.
