spanky Posted August 28, 2010 Share Posted August 28, 2010 Can you guys help me diagnose this? I have a Glock 34 that I have personally put about maybe 7-8,000 rounds through and it has gone through, since I acquired it last April or so, about 4 trigger springs. It has gone through one factory spring before I changed out a few things and now has gone through three more Glockworx springs. Last time this happened, it was breaking on the side of the trigger housing so I swapped that with a spare that I had. This time it broke on the trigger bar side. Is it reasonable to assume there might be an issue there as well? I think I may have a spare trigger bar and, if not, I can order one. Just wanted to get some opinions from some more experienced people. Link to comment Share on other sites More sharing options...
Sarge Posted August 28, 2010 Share Posted August 28, 2010 (edited) Sorry, no problems at all yet with my 34. But I will be keeping an eye on this thread. Edited August 28, 2010 by Sarge Link to comment Share on other sites More sharing options...
BayouSlide Posted August 28, 2010 Share Posted August 28, 2010 (edited) Are you perhaps stressing it at the "loop" bends when removing it during detail strip/cleaning? I have broken only one trigger spring (a reduced Wolff which I won't use any longer) in 55K rounds. You've probably already checked the spring hole on the trigger bar for roughness/sharp edge. If the spot where it's breaking is consistent with this, you could put a chamfer on the edges of this hole.

Glockcomma Posted August 28, 2010 Share Posted August 28, 2010 I always carried spares but only broke one in about 18 years of shooting Glocks. Use Glock factory springs and make sure they are installed correctly, the opening on the spring should be down at the trigger bar or it will bind and break.

But seriously, no, I try my hardest not to pull on the spring during installation or removal. Link to comment Share on other sites More sharing options...

Tim I'll double check this (I'm at work right now) but I'm relatively certain that it is installed as you described. Link to comment Share on other sites More sharing options...

Jman Posted August 28, 2010 Share Posted August 28, 2010 Wow. Very VERY odd. Never heard of this at the breakage rate you are describing. Some geometry is way off and/or your trigger springs are junk. Make sure it's installed right...meaning the spring should have a "S" shape looking straight at it with the trigger in your right hand above the trigger mechanism housing in the left.

Biloxi23 Posted August 29, 2010 Share Posted August 29, 2010 I've been a Glock armorerfor a police departmetn since 1995 and the only ones I've seen broken were the ones that were installed backwards as some of the previous posters observed.

vluc Posted August 29, 2010 Share Posted August 29, 2010 LOL! I've only had one trigger spring break in 9 years of running a glock, and it was a stock one. I use either the factory or glockmeister springs. You may have it installed wrong, but still, three of them? From Charlie Vanek's site: Link to comment Share on other sites More sharing options...

dsmw5142 Posted August 29, 2010 Share Posted August 29, 2010 That seems really odd I have worked on tons of Glocks, my own and several hundred department guns. While I have fixed quite a few parts over time, I don't recall any one gun going through trigger springs like that. My suggestion would be to try a new trigger w/ trigger bar. I know you said you replaced the trigger housing, but the trigger bar is the part that moves and may be putting some type of undo stress on the springs. Last time I checked they were still pretty cheap. Worst case scenario (other than still having the same problem) is you have an extra part if you ever need it. Is it a factory connector? You may wish to try a replacement for that part as well. The angle of engagement with the trigger bar by be stressing the spring? If you have another 9mm Glock, just switch out the whole trigger group and see if that solves the problem. If that doesn't work, call Glock and see if they will send you a shipping label. Hopefully my educated guessing helped some Link to comment Share on other sites More sharing options...
vluc Posted August 29, 2010 Share Posted August 29, 2010 Mine looks just like the picture. Then I would look at a different spring. If you are putting them in correctly, the only other common thread is the spring itself. Link to comment Share on other sites More sharing options...

Glockcomma Posted August 29, 2010 Share Posted August 29, 2010 Has the front spring attachment point been relocated by someone doing trigger work? I relocate it on all the Glocks I do trigger jobs on, but If you leave the original hole as is the current trend you have to make sure the spacing is correct or it will bind. This would be two holes on the trigger bar tang, you would use the top one and snake the loop on the spring through the bottom one. Tim Link to comment Share on other sites More sharing options...

Were all these changes made at the same time and before you had the problem? I'd suggest you remove all the glockworx stuff, go back stock and change items one at a time, run them, then see what happens. There is the possibility that your spring combination's are at fault. Flex talks of the imbalance when you get these wrong. There is a proper mix to recoil, striker and trigger springs with Glock. Link to comment Share on other sites More sharing options...
Aircooled6racer Posted August 29, 2010 Share Posted August 29, 2010 Hello: Check the trigger bar for a burr. I would also contact the spring company to see if they have had problems with there springs. I would also try a stock trigger spring to see how it lasts. Thanks, Eric Link to comment Share on other sites More sharing options...
Duane Thomas Posted August 30, 2010 Share Posted August 30, 2010 My gut instinct is that if the spring is breaking, the problem is probably the spring. Simple I know, but simple answers are frequently correct. Try going for one of the current production battleship gray factory Glock trigger springs and see if that solves your problem - which it probably will.

BlueOvalBruin Posted August 30, 2010 Share Posted August 30, 2010 I got a new G35 last september. Within 200 rounds the trigger spring broke, then the replacement broke at around the 1000 round mark. Both stock parts. I'm using a glockworx spring now and no problems. It could just be a bad batch of springs, not unheard of. Link to comment Share on other sites More sharing options...

JonInWA Posted August 30, 2010 Share Posted August 30, 2010 (edited) I'll suggest several things for your consideration- First, as others have recommended, simply go to, and stick with, the OEM current-production battleship gray Glock coil trigger spring. Second, More recent production Gen 3 (and by definition, Gen4) Glocks have had the spring attachment holes both in the triggerbar and the trigger housing mechanism components slightly enlarged, to reduce flexation stress/fatigue on the spring portions in contact with the inner hole wall during the action sequence-so you might want to replace you trigger housing machanism and your triggerbar for new ones-which leads to... Three, Glock has just introduced an product-improved triggerbar, which has a sort of a "dogleg" bend and a channel for the spring attachment point; the purpose for the improvements is to further reduce potential spring wear/fatigue. While it arguably may be overkill (as others have mentioned, failures of the battleship gray coil trigger spring are extremely rare), it might be worthwhile to consider; I'm keeping my "non-dogleg" triggerbar in my G17 (partially as a comparison, more because it's sinfully nice as is), but have just put the new "dogleg" triggerbar in my G19. On a gun running a NY spring, it's irrelevant as to which one you go with, as it appears that the "dogleg" is the only running change, and that portion of the triggerbar is irrelevant to the activation of the NY springs. And to head off the inevitable ensuing question, no, this is NOT the Gen4/G37 triggerbar-it does not have the blister on the vertical extension. And Fourth, I suppose you could alternatively simply ditch the coil trigger spring and elect to go with a NY1 spring and the "-" 4.5 lb. "minus" connector...
