...I'm getting fed up with Glock's ejection problems and just about to jump ship. I have 5 Glocks all Gen 4...a 26, 19, two 17's and an extra Glock slide for one of those, and a 34. The oldest (a 17) is about 18 months old and the newest ( the 19) about 3 months. Every single one of those barely ejects a casing. I catch my casings on a net when shooting outside. If I stand on the edge of the net, some casings miss the net at my feet. They are falling straight down from the ejection port.
I am not a weakling who allows uninhibited muzzle flip. I am not an occasional shooter. I shoot 6 days a week routinely. I shoot both factory ammo and reloaded ammo of both high and low PF. I shoot at least 5 different powders (by necessity) and 115 and 124 grain FMJ round nose bullets from brand name manufacturers (mostly Montana Gold, but not all). It makes absolutely no difference. The casing barely escape the gun. Other than sights, my guns are (until now) stock. I have Lone Wolf extractor for my 34 on the truck now so we will see what happens....
I've been thinking about your post for a few days, wondering what could be going wrong here that's causing your frustration. Can't say I really have an answer. Since it seems that you've read earlier posts on the topic, I'll assume that your guns have the current parts (especially the ejectors), and that they all have enough rounds through them to be considered "broken in", so that the coating is worn on the top and bottom of the extractors.
One thing I will suggest: if your Lone Wolf extractor does make a difference for you, the first thing I would do is to really scrub the claw of your other extractors with a wire brush, to make sure that they're as tidy as a new one. If you shoot a lot (and you do...), carbon buildup on the extractor
might be a factor here. That's really grasping for straws, isn't it?
Oh, one other idea: if you've taken the guns apart, be sure to get the EDP assembly inserted so that the metal end is touching the extractor. If you reverse them and put the polymer Spring-Loaded Bearing against the extractor they really won't work well at all. Don't laugh, I've seen this happen.
I wonder if maybe the Glock extractor claw is shallow compared to other makes..hmmm...something for me to look at. I'll do that later today and will come back to this thread with the results. I'll compare the claw depth of the standard 9mm Glock LCI extractor, the non-LCI extractor (I think I have one), the Lone Wolf Extractor, and extractors from a 1911, a Beretta 92Fs, and a CZ 75 Shadow. A little data might tell us something.
For ammo I shoot mainly competition reloads (147-grain Montana Gold bullets at about 880 fps), some Winchester NATO, some Winchester White Box, Fiocchi, Federal, and Magtech (whatever is available through retailers), probably similar to what you're using. Right now I'm shooting a G34 frequently, a G19 once a month or so, and a G17 when I realize I haven't fired it for a few months. Most of my Glock time is spent with the G34 in USPSA matches. They all exhibit the same 100% reliability in cycling and ejection.
Personally, I don't pay a lot of attention to where the empties go unless they are jamming or hitting me in the face. I did have some Brass-To-Face (BTF) problems a long time ago, but they were cured by the new 30274 ejector. Generally my brass is off to the right rear, about 2-3 feet if I recall correctly. The last time I had a stovepipe jam in a Glock was literally years ago, when I had just acquired my first one, a Gen4 G17. In my case, it was purely a skill problem, I didn't know how to hold ANY pistol properly.
My Beretta is a 92FS, and although I don't know where the empties go, I do know that I don't have problems with it, but that is a heavier gun, really designed to be able to function reliably with very little training. One thing that I've learned that separates the Beretta from some other makes is that it seems to fit small hands well, with a nice short reach to the trigger. This thought takes me off on a tangent, so I need to ask: do Glocks fit your hands well, and since you're using all Gen4 guns, what backstraps (if any) are you using? Maybe we've got a fit problem that is contributing to a handling problem. Just asking, fishing around here, trying to come up with ideas.
I wonder, have you had a friend shoot your Glocks and have the same kind of problems? That might tell you something, at least it would rule out operator error.
So, stay tuned for a update on the extractor claw depth, that might be significant or it might not, at least I'll post up a little data for further consideration.
And please try to hang in there with your Glocks a little longer, for no reason other than to try out a few ideas and see if the dialog brings forth other suggestions. We might just make some progress!
