1st range trip:
100rds AE FMJ 230gr at indoor range. Did notice brass to the head/face/shoulder. Did not pay attention because I am so used to brass bouncing off the partitions and hitting me.

2nd range trip:
50rds PMC FMJ 230gr and 50rds Blazer CCI Aluminum FMJ 230gr. at outdoor range. No PMC brass to the head. About 5-6 alum blazer casings to the head/face. Maybe 2 Blazer casings to the shoulder.

3rd range trip:
50 rds Independence FMJ 230gr and 50 rds Blazer CCI Aluminum FMJ 230gr at outdoor range. About 15 casing to the head/face from both brass and aluminum casings. About 6 casings from both brass and aluminum to the shoulder.

Diamond, same situation happened with my G21 gen 4, serial # TAU. I had a post elsewhere on GT last week.

I shot several hundred rounds of 4 different types of factory ammo, all caused many cases to eject onto forearms or at my face. Right side ejects were also weak.

I locked my slide to rear for a week and then had same results. Shot 650 rounds until I'd had enough and the gun is now back at Glock with a long note on what is happening, what I did, and told them to run a lot of rounds through it before simply replacing a part or two and sending back.

On a side note, the ejector would hit the plastic slide plate when I reattached the slide after field stripping to the extent that I had to lift the rear of the slide when reattaching it. I told them this too.

Second Glock I've sent back. They fixed my G23 right when I had an issue of that ejector causing the slide to hang up, so I have confidence. Sucked to pay $68 for next day shipping, but the place I bought it from is 90 miles from my house and not worth the time and fuel cost.

Good luck with yours. I will post any fix they perform when I get my pistol back.

Buzz,
Do report back with what parts they change and the end result. I really don't want to send mine to Glock. If its something as simple as an extractor, I can do it myself.

In any event, this looks like the first instance of erratic ejection with a G21 gen4 that has popped up on GT, with probably thousands of guns sold most likely. Hardly an "issue" unless quite a few more pop up.

Here ya go. Just under 500 rounds

My G21 isn't even launching most of the shells I fire that far. I get hit in the forearms far more than the face.

How many of your Glocks are Gen 4?

If you have NO gen 4....then your reply was kind of dumb.

BuzznRose · 08-09-2012, 06:34

I have four Gen 4's, a 19, 23, 26, and 21. Only the 21 throws brass straight back or short.

Never had an issue with FTF/FTE but both the 19 & 23 had recall recoil springs that Glock replaced. No issues before or after new springs.

Did have an issue with the way the 23 slide seated...but Glock fixed it quickly.

That's what it looks like when I shoot my Gen4 G21. Although it's not every round like in this video. I did notice in the video the casings look like they are either steel or aluminum. The aluminum seems to worse than the brass.

I also have Gen4 - 2-19's, 26, & 23 that do not eject brass to face.

1-2man · 08-09-2012, 07:14

My Gen 4 21 ejects rather weakly 3-4 o'clock but only with my reloads (very light.) Full loads and personal protection ejects strong.

Ranger45 · 08-09-2012, 17:59

Gen4 G21 SSN###, spent casing collected 3/8/12, purchased in May 2012. No issues with ejection yet.

awpk03s · 08-09-2012, 21:11

I have a Gen4 G21. No problems here of any kind.

diamondd2 · 08-10-2012, 07:14

I went and ordered a new ejector (trigger housing) and new extractor from Glockparts. I also went and ordered a 250rd bulk pack of American Eagle 230gr FMJ. I paid the extra $$ for the AE because it is rated at 890fps and the poorly ejecting stuff I used was 840fps and less.

What my plan is:

-Clean and Lube
-Change to new ejector
-Use original extractor

Run 5 mags with original extractor, observe ejection.
Run 5 mags with new extractor, observe ejection.

Keep better ejection pattern extractor in.

This will be sometime next week

Slightly off topic but how do you like your xs sights?

Ok. Interesting devolpement. I recieved my new trigger housing with the 8196-2 ejector. Installed it in the pistol. 1st thing I noticed is the new ejector sits higher in the housing then the one that came with my G21 (maybe a 1/16"). Now my ejector is up tight to the bottom of the slide (seen when retracting slide). 2nd thing I noticed is the angle on the new ejector is a little more to the right then on the original one. I have a good feeling this is the source of my problem.

I also recieved a new non-dipped extractor with the #2 on it (my original is a #3). I will only put this in if the new ejector is not enough to fix the BTF problem.

I will get my ammo hopefully in a couple days and try it out.

You ordered a new non-dip .45 extractor? So it's true Glock is making non-dip extractors for more than just the 9mm? If true, depending on your results may make me reconsider the Glock as my platform of choice.

MY G21 Gen 4 came with a non-dipped extractor. The new one I ordered just happened to be non-dipped, I didn't specifically order non-dipped. I might be wrong, but I think all .45 Glock Gen4's are non-dip.

Beanie-Bean · 08-13-2012, 15:18

diamond,

I've got the 8196-2 ejector, 4256-1 cruciform/trigger bar, and a non-dipped extractor with "6." stamped on the inside. 0-7-2 RSA.

No weak ejections unless I didn't put enough powder when I loaded the ammo, and none w/factory.

bruzer · 08-13-2012, 15:32

Following the progress.
Mike

Bean,

Does you ejector sit "high" in the trigger housing like my new one or "low" like my original?

PopandGlock · 08-14-2012, 19:28

Has this issue been resolved by Glock yet?

I was showing you and the rest of the it might be this and not the gun people that the problem is real. That it's the gun and not a ricochet.

bruzer · 08-15-2012, 00:34

Hey diamond,
My Gen 4 G21 came with the 8196-2 ejector and it sits down like your original ejector. I am guessing your new one should also and is not properly seated.
Good luck and stay safe,
Mike

diamond,

Mine sits low/flush like your older one.

ricklee4570 · 08-15-2012, 03:27

Nothing more enjoyable than going to the range to shoot your new gun and then getting pelted in the face with hot brass every shot!

Upon closer inspection (idiot I am), it's the trigger housing that's a little different which gives the illusion of the ejector sitting higher. When in fact it's the same height. But the angle of the ejector is slightly different, which is what I am hoping will change the ejection. I might have just got a defective ejector. If not, it's got to be the extractor. There are no updated ejectors and everyone is running the same 8196-2, and most have no problems. But there are lots of different extractor casting #'s (at least 6).
