Piney Posted June 2, 2013 Share Posted June 2, 2013 (edited) I surrender-- My G34 stopped running at the TX state. Over and over, after the first round-- maybe 2nd round-- FTF-- some could be shaken loose, most jammed up good . Tried a different set of mags-- no help. I did a quick field strip -- no help. I dug out some commercial 124g ammo- no change. Got home and did a full cleaning. Replaced the recoil spring (same stock Glock model). Replaced the extractor and its spring for good measure as it was 18-24mo old. Went out to hopefully shoot more than a single shot-- slight change but still FTF every 4-5 rounds. Came home and I replaced the springs with stock Glock and followers in several mags. Went out this afternoon-- still FTF every few rounds. Tried my reloads, some commercial 124g ammo and even some 115g Lawman brand-- same thing I surrender-- What's left to replace ??

ericjhuber Posted June 2, 2013 Share Posted June 2, 2013 (edited) Is it a situation where you are pulling the trigger and the round doesn't fire? Are you getting good primer strikes on your FTF? Given all that you've swapped out so far and the fact that you've tried all sorts of ammo, I start to wonder what the story is with parts related to the firing pin if you're getting failure to fire (as opposed to failing to extract if you have consistent good firing). If you get enough debris, oil, etc around the firing pin and firing pin spring, it can end badly where you aren't getting consistent performance that you require out of it. The firing pin might just be fine, but if there is a lot of stuff there that shouldn't be, it can be hit and miss (so to speak). So it might not be a matter of swapping anything out, but a matter of doing a full disassembly and cleaning of the slide and its components. If you take the slide off your receiver...shake it around hard. Do you hear anything? If it's silent, then I really start to think we've got an issue with the firing pin, etc. You should hear some moving around there. If not, it could mean that there is so much gunk (the technical term) there that the firing pin is being restricted from doing what you need it to do consistently for you.

Piney Posted June 2, 2013 Author Share Posted June 2, 2013 (edited) Sorry I wasnt clear-- it fires-- one or twice, then jams. The round sticks at a 45 degree angle, nose stick at the top of the chamber. I should have said Failure to Feed. Thanks for the insight on the firing pin and area. Cleaned that out and it does rattle. If a round gets chambered-- it fires. No lite strikes On another note along the firing pin lines-- I did notice a tiny little nick on the breach face pin's hole. But since it does fire that's probably not an issue. Edited June 2, 2013 by Piney Link to comment Share on other sites More sharing options...
Sarge Posted June 3, 2013 Share Posted June 3, 2013 Recently put a magwell on it? New mag release? Sounds like a mag issue. Maybe the mags are not seating true if you did either of the two. Link to comment Share on other sites More sharing options...
maxpower Posted June 3, 2013 Share Posted June 3, 2013 does it have an aftermarket barrel? i know my lone wolf g22 barrel has that same issue. it rides up on the feed ramp then gets stuck going into the chamber with the flat nose umc ammo.

Piney Posted June 3, 2013 Author Share Posted June 3, 2013 No magwell Same stock mag release Stock barrel Mags aren't loose when seated. I can't make one wiggle at the base so one could assume it seated properly eh ?. That's a part I haven't replaced though. Link to comment Share on other sites More sharing options...
Fitzghan Posted June 3, 2013 Share Posted June 3, 2013 Are you using reloads or factory ammo and do you case gauge the ammo you shoot? If the rounds are feeding partially and getting lodged in the chamber it could be the ammo. If you case gauged the ammo then you can eliminate this possibility. If not I’d check it out. If you always reload on the same press and this suddenly became an issue maybe check your dies. Link to comment Share on other sites More sharing options...
Fitzghan Posted June 3, 2013 Share Posted June 3, 2013 Oh…just saw that you tried some other ammo. Not likely but if you didn’t gauge it, it could be the problem. Link to comment Share on other sites More sharing options...
Delmont Posted June 3, 2013 Share Posted June 3, 2013 You didn't mention whether you had fully stripped the frame when you cleaned it. Have you inspected the locking block for a crack or missing chunk? How about the bottom lug on the barrel? Does it look OK? Also inspect the frame rails to see if one is cracked, bent, etc. Probably a reach, but this one sounds weird. Link to comment Share on other sites More sharing options...

Glockman1000 Posted June 3, 2013 Share Posted June 3, 2013 How deep is the nick on the breechface? You mentioned G4, does this mean a G34 Gen 4 Glock with the dual recoil springs? Glock revised the design on that part. Had something to do with breakage & reliability issues in early Gen 4 models. You may want to contact Glock to see if your model needs the updated RSA. As mentioned earlier, a full detail strip & locking block inspection may be in order. I would also suggest checking you slide release & spring. If they somehow get out of place they could cause some problems. Hope you get it sorted out soon. Link to comment Share on other sites More sharing options...
Piney Posted June 3, 2013 Author Share Posted June 3, 2013 I"ll take it apart again and look for dings/cracks etc -- Its a tiny tiny nick on the breach face on the side of the pin hole Its a GEN 3 Mag feed lips-- I tried several different mags, of different vintages. I think I've got 3-4 NIB in the closet somewhere. What does one look for on the mag feed areas edges-- bent, worn, missing ? Re: Ammo-- same press, same settings. OAL on reloads is what it's been in the past. Reloads jam, two different brand comercial ammo jams. Link to comment Share on other sites More sharing options...
Ken_Bird Posted June 3, 2013 Share Posted June 3, 2013 Just for fun..... LOL check you loaded reload rounds look near the head of the case pretty close to it. See if you can see the famous glock bulge Link to comment Share on other sites More sharing options...
Glockman1000 Posted June 4, 2013 Share Posted June 4, 2013 Are you able to pull the slide back a little, release it & chamber the next round or is it locked up completely where you have to fully clear it? If you can find those other mags, give them a shot. Link to comment Share on other sites More sharing options...
fishhunter3 Posted June 4, 2013 Share Posted June 4, 2013 do you have the slide stop in backwards,if it is the barrel is set back a bit and you will have feed issues Link to comment Share on other sites More sharing options...
LarryP Posted June 4, 2013 Share Posted June 4, 2013 What about the magazine springs? What are they?...Glock Stock, Extra Power, Another Mfg.? or more importantly... How old are they? They may be too weak! I had a similar problem (although not as bad as yours.) In the end it turned out my mag springs needed replacing. As a precaution I change the followers as well.

Hi-Power Jack Posted June 4, 2013 Share Posted June 4, 2013 The round sticks at a 45 degree angle, nose stick at the top of the chamber. Does the fired cartridge case fully extract & eject? Link to comment Share on other sites More sharing options...
Piney Posted June 4, 2013 Author Share Posted June 4, 2013 The round sticks at a 45 degree angle, nose stick at the top of the chamber. Does the fired cartridge case fully extract & eject?

Tom C Posted June 4, 2013 Share Posted June 4, 2013 Don't know where you are Piney but sounds as thougg you've done everything short of going to a Glock armorer or sending it back to Glock. When you say you cleaned everything, did you make sure you had no hard buildup on the breach of the barrel? I'll talk to my friend who also happens to be a Glock Armorer and see what he thinks.

Piney Posted June 4, 2013 Author Share Posted June 4, 2013 Yeah, I checked the breach area- nice and clean. I've made arrangements to drop it off at a gunsmith next week. Link to comment Share on other sites More sharing options...

Robogunner Posted June 13, 2013 Share Posted June 13, 2013 Try running your fingernail (thumb) up the receiving ramp and see if it has a burr. If so polish it away. Link to comment Share on other sites More sharing options...
