mbuckdc Posted June 1, 2021 Share Posted June 1, 2021 I have a gen 4 Glock 34. It has 15-20k rounds through it, and lately the brass is ejecting and dropping at my feet. I have not had a malfunction but afraid a stovepipe issue is in my near future. The extractor spring, extractor, and recoil spring are all original. I am guessing one of these may be my culprit. I am shooting the same power factor as I was some time ago with better ejection. What parts should I look at to fix this?? Link to comment Share on other sites More sharing options...
Edwards30 Posted June 1, 2021 Share Posted June 1, 2021 At that sort of mileage, you might as well replace all the springs. I was having issues with weak ejection and a new ejector from a Gen 5 helped. That wouldn’t be your issue though since it’s a new problem. Big Tex Ordinance is where I grab my Glock parts from, they are closed today though and have their site off it appears. Link to comment Share on other sites More sharing options...

Braxton1 Posted June 3, 2021 Share Posted June 3, 2021 Has there been any change in ammo? In today's "ammo shortage" world, Quality Control seems to have exited stage left. I recently encountered a bunch of 40 ammo that was advertised as the nominal "180 grain at 950 fps" standard. When test-firing a few guns, I noticed the same weak ejection issue as the OP. I knew the ammo wasn't right because I have gotten quite "recoil averse" in my old age and I notice it when shooting 40 and 10mm. Chrono'ing that lot of ammo revealed that it was only going about 750 fps. Link to comment Share on other sites More sharing options...

CharlieD Posted June 3, 2021 Share Posted June 3, 2021 The Apex extractor fixed weak ejection in my Gen4 guns. Link to comment Share on other sites More sharing options...

Cuz Posted June 3, 2021 Share Posted June 3, 2021 I agree with Edwards30 suggestion that you might as well replace all the springs. It’s cheap enough to do, that it should be an automatic at that number of rounds. Now that I think about it, at 20,000 rounds it’s also probably time for it’s second cleaning as well.

Bowman Posted June 13, 2021 Share Posted June 13, 2021 I would definitely replace the springs, especially the recoil spring. 20 K rounds is quite a lot for a recoil spring and the others as well. Link to comment Share on other sites More sharing options...
OSP737 Posted July 15, 2021 Share Posted July 15, 2021 Another vote for replacing the recoil spring. Link to comment Share on other sites More sharing options...
Ajsomp Posted July 21, 2021 Share Posted July 21, 2021 I had this on my 17/sro combo and swapping out the RSA seemed to do the trick. That said - anyone have an aftermarket RSA where you can just replace the spring or just buy a bunch of factory ones and toss the old one when you’re done?

rooster Posted July 21, 2021 Share Posted July 21, 2021 Aftec extractor, get the ejector that’s in the gen5 guns if you can find one. Change rsa to a 13 lb spring and you should be gtg. Link to comment Share on other sites More sharing options...

Trump Posted July 25, 2021 Share Posted July 25, 2021 It sounds like you may have debris caught under the extractor or your rounds have a low powerfactor. Link to comment Share on other sites More sharing options...
tdp88 Posted August 6, 2021 Share Posted August 6, 2021 I agree on the extractor plunger spring. I would think a worn recoil spring could cause the slide to move much faster and cause the brass to eject faster and further. Link to comment Share on other sites More sharing options...
MemphisMechanic Posted August 6, 2021 Share Posted August 6, 2021 First clean the hole for the plunger and spring and around the extractor like crazy. ….and replace all the springs in the gun every 10-15k just as general maintenance. Link to comment Share on other sites More sharing options...

Take a look at these from NDZ: https://www.ndzperformance.com/NDZ-Glock-Gen-1-3-SST-Guide-Rod-17-22-24-31-34-35-p/ndz-glk-gro-g17.htm I use them and like them a lot.

What Memphis Mechanic said above. I went through this same problem with a Glock 17 Gen4. Tried the Apex "Failure Resistant Extractor" but later switched back to Glock OEM extractor and all was good. Didn't find the Apex extractor worked any better than Glock OEM. Link to comment Share on other sites More sharing options...
