Glock 43X trigger spring failure

Anyone else have a failure like this? Trigger went dead at the range during my last session. The little hook broke off. I have close to 10k on the gun. I had a spare so no big deal, but was curious if it's common???

AFAIK - not very common.

Suggestion - send this picture and explanation to Glock. They might send you something?

ETA: I also noticed that your spring rod and bearing does not have the correct orientation in your picture (maybe this got moved after removal?).
Refer to the illustrated small circled picture from Glock Armorer's Manual:

I remember at my last Glock Armorer's recertification that the instructor mentioned that the orientation is important.

Parts break - good to have a spare. I will have to order a couple.

The spring rod is correct when installed. I replaced the part. Probably won't bother Glock about it unless it happens again, I was just curious if anyone else has broken these.

No, I have not seen the Slim Line trigger spring bearing broken like that....
In my experience with the G43s, which uses the same TMH as the G43X, that small trigger spring bearing should last far more rounds of live fire plus dry-fires. If it broke only after 10k rounds, perhaps the bearing was defective to begin with....

As a matter of fact, even when the Trigger Spring itself broke literally in two pieces inside the TMH of my G43 after about 41k rounds of live fire (plus numerous dry-fires), the original trigger spring bearing was still in a very good shape with no damage or deformation. Because the the trigger spring bearing was intact, my G43 kept functioning reliably even with the trigger spring broken into two pieces inside the TMH. (See this thread for detail: Keep your Glock parts handy!)

In any case, this broken trigger spring incident is one of the reasosns why I now have the NY-1 trigger spring (Part #39324) in all of my Slim Line models along with an aftermarket "3.5 LB" connector...

I'm glad I had a spare. I ordered a few more from Ghost. It's nice to be able to fix things right away.
Does Ghost sell OEM? I would not buy an aftermarket trigger spring.

FFL & Glock stocking dealer here. We sell NIB guns and have seen this happen exactly twice. 1st time was a G19.5 when they first came out, out of the box as we were removing the trigger bar it snapped. Glock sent us a replacement at no cost.

The second was a customer with a fairy new gun and this spring failed on a first range trip.

Glock has good warranty and good customer service, they will send you a new trigger housing at no cost.

Haven't heard of it happening among the Slimline or Gen5 Glock users at my former agency, but that's obviously a small sampling.

10+K rounds is a lot of usage for the 'average' Glock owner/issued user. If the manufacturing 'fold' of the hooked part of the trigger spring bearing had a sharp bend ('corner') on the bottom, it might've created the potential for an eventual stress riser.

Heavy use guns may benefit from some preventive maintenance replacement of parts. Dunno if Glock is currently considering that spring/bearing assembly as a Wearable Replacement Part. I usually replaced the trigger coil springs in my own Glocks (Gen3/older) sooner than 10K rounds, and if I were running a newer Glock with Gen5 parts I'd probably perform much the same periodic preventive maintenance replacement of some parts.

Did you remove or change it before this happened?

I don't think they sell them even to armorers.
Buy a Trigger Mechanism Housing.
The spring [unlike previous generations-all G5's and slimlines] comes installed in them

The plastic side 'rails' of the TMH (on which the wings of the cruciform rest & slide) might end up being worn enough to merit replacement of the TMH after 10K rounds, anyway.

I had to do that with my G27 to get engagement back in spec at something like 12K rounds, as replacing the FP and the Trigger Bar weren't enough to do it (which conformed to what we were told about hard-used .40's in one of the update classes). Sometimes it might take the TMH, FP and the Trigger Bar to restore optimal engagement spec in some guns ... all 3 assemblies ... which is what happened with mine.

It's so easy to replace the whole TMH assembly, anyway, and the new spring/bearing would already come with it.

I got a few TMH's from Ghost. I'll replace it next time before 10k like I do with the other springs. The pistol is back in action ready for another 10k. Besides the ammunition, I've dryfired this thing countless times. I honestly thought it would have been the little black plastic rod to break before anything, but that part seems fine. I tossed the whole TMH to be safe.
