Based on your description alone the indicators point to the ejector. That said I would not venture to make a complete diagnosis without seeing the firearm, the brass that has been ejected, the brass that stovepiped, and of course a sampling of the other brass that you indicate ejected without a problem. The subtile marks on a case can speak volumes about how a firearm is functioning. It appears you have been feeding your 19 a varied diet since it's purchase and have only one feed malfunction (caused by FTE). Please take the time to closely examine your spent brass and note if you are seeing any inconstistancies especially with the Hydra-shok rounds. They have been notorious for splitting or base rupture. As a personal note the Hydra-shok is the only round I have ever returned to the manufacturer for a closer inspection as a possible bad lot.

Do NOT give up on your Glock......both Glock and any Glock Armorer will go to great lenghts to ensure your Glock will perform as designed......EVERYTIME.

Be SAFE.....Shoot WELL

The first 100 rounds were American Eagle 115gr. My 47th shot was a stove pipe. Rest ejected fine except for the occasional ejection to my head.
The next day I shot 200 rounds of the same ammo (American Eagle 115gr) no problems except for the occasional ejection to my head and a couple the left. But this time no failures and I was sure it was something other than the gun that caused the failure the day before. Perhaps limp wristing or a bad round.
This morning I called Glock Tech Support and told them about my erratic ejections and that I saw that there was an updated ejector out there (30274). They said that they would send it out to a certified glock armorer free of charge and they could install it. The tech guy said that there were no problems with the extractor. I called the shop where I bought the gun and the gunsmith (who is a CGA) said he would order it and get back to me when they got it. He asked for my serial number to give to Glock.
So tonite I shot 185 rounds total. I started with 15 rounds of WWB. Everything fine (no failures) except for erratic ejections. I then shot 50 rounds of Tula. I probably won't shoot that again but I had no failures. Tula ammo makes sparks come out of the ejection port and it feels kinda "light" and sounds different. I then shot 15 rounds of WWB and on the 4th shot I had a FTE resulting in a double feed. The empty case was sitting in th ejection port parrellel to the slide almost half way out holding the slide open and there was a live round in the barrell. I cleared it out and loaded the round in the barrell back in the clip and finished the rest without failure. I was pissed. I then fired 5 rounds of Hydra Shok with no problems as I wanted to see how my home defense ammo would shoot. No problems with ejection with the Hydra shok and no failures. I then fired 85 rounds of WWB with no failures. But again I had erratic ejections.
This time I noticed that some of the rounds would shoot straight up about 6-8 inches. This happened enough for me to take note although I didn’t count how many. Same as casings shooting off to the left. It happened more than I noticed the first 2 trips to the range but I don't have an exact number but I’d say more than 5 times to the left and perhaps 10 times straight up about 6-8 inches.
I’m starting to worry. Do you guys think that the new ejector will fix this or does my gun need a new extractor? I was so happy when I first got this gun but now I’m regretting it.

Try shooting some American Eagle 124gr ammo.... It should help your FTE problems...

The 30274 ejector is designed to work with the Glock 19 043 recoil spring assembly. It should help with the erratic ejections...

Peace,

You are to be commended for taking notes and keeping records! I know that encountering the problems you have seen can be disheartening, but you have noted some possible causes, such as a light round and possibly limp-wristing the pistol once or twice. It sounds like you have some sort of scientific or problem-solving training. It is rare, and good to hear. You are not afraid to look at all of the evidence before drawing a conclusion.

The short answer is that the new ejector will solve the problems you have encountered that are not associated with ammunition or technique.

It seems to me that erratic ejection (mis-handling the empty case as it is moved out of the pistol) is caused by some combination of factors: ammunition, Recoil Spring Assembly, extractor, and ejector. I was able to solve the problem in a Gen 4 G17 using a different extractor, which I later learned was really a .40 cal extractor that was mis-shipped. The real cure that Glock has settled on is the newly-designed ejector (marked 30274, as __jb has noted). I have one of these in a new Gen4 G34, and it ejects perfectly. No other changes to the pistol were made, it has the original RSA and extractor.

Hang in there. While it is embarrassing to have to fix a problem like this in a brand new gun, it will be worth it in the end. The Gen 4 G19 is my favorite Glock.

In the mean time, practice your drills to clear jams, which should be a part of training for any semi-auto handgun. You may have had one ammunition failure already (light load), and you will certainly encounter others over time.

My gen4 G19 also has had some erratic ejection issues. I sent it back to Glock and the installed the new 30274 ejector, and while the pistol operates fine, no FTE or FTF problems, I still get less than perfect ejection.

I have a Lone Wolf extractor that I bought a year ago, and that part solved the issue in my gen3 G17L. I'll install that extractor in my G19 and test it to see what the new ejector and a "good" extractor does to the gen4 G19 and report back.

I have another Lone Wolf extractor that I bought more recently, and it's "different" than the "one that works"... I've "heard" that Lone Wolf sold some extractors marked for 9mm models, but were actually for .40 cal. That may explain my inconsistent results with the "Lone Wolf fix".

To the OP, hang in there, from what I've read from you, I'd suggest you try 124 gr American Eagle, but we should all be able to expect our Glocks to run well on decent 115 ammo and not rain empties on us. Lot's of folks are working on this. AND, it's not just a gen4 thing.... all the current 9mm Glock models are prone to this issue.

I believe its the 045 spring, and the new 30274 ejector that you will need. You can send it in your self and save the cost for the armor to do the work seeing how your the owner, call 1-770-432-1202. There is no charge for the replacements from Glock if you send it in your self.

Any issues with the RSA and ejector were not taken care of until test fire date in November 2011. I've been trying to find the information that backs up what I'm saying, I guess your best bet is just call Glock. Yours fell into the bad area.

0-4-3 spring not 045. In other words your spring is correct your ejector is needing replaced. Your RSA was replaced after the volunteer recall so your ok, but you do need to call about your ejector.

When I spoke to the Tech support guy at Glock he told me to have my armorer contact Glock to get the part. So I had the CGA at the shop where I bought the gun at contact Glock and he ordered it already so I'll wait to see what happens when the part comes in. It's funny because guys at the shop where I bought my gun acted like they never heard of this problem but I guess they didn't want to talk about it in front of customers. I should have done more homework and bought a gun with a later test date but I thought I was safe because my gun had the updated RSA.

I fired 170 more rounds (WWB) today which brings the total to 655. Had a FTE with the 64th round resulting in a double feed. It was sitting parallel to the slide holding it open. It was the 4th round in the mag. Rest fired with no failures. I was using WWB. I showed the brass of the FTE to the range guy and he looked at it and said it was probably a bad round as the brass looked OK. He looked at the end that comes in contact with the striker and the side where the ejector hit and said it looked normal. HOWEVER, I still had the occasional erratic ejection (to the left, straight up and to the face).

So far 655 rounds.
300 American Eagle 115gr: 1 stove pipe on the 47th shot
50 Tula 115gr: No failures
5 Hydra Shok 135 Gr: No failures but sometimes when I load the hollow points into the chamber they tend to "catch" before going into the chamber. Is this normal because of the hollow point? Again I'm new to this!
300 WWB: 2 FTE resulting in double feeds.

I cleaned my gun today because I'm not going to the range for a few weeks and I noticed that my spring and my ejection port had some wear to it.

Is this normal?

Peace
