I'm ashamed to admit that I've been Glock armor for many years but let it lapse about 5 years ago. Since that time, I have a G43 of which I really like. Discovered today that racking the slide does not reset the trigger, it still appears at the back in the fired position. I detail stripped the frame (not the slide), cleaned it and re-assembled. Same problem and must admit that I'm not sure what area to focus (never worked on anything later than G3s) Any help would be appreciated. For what it's worth, if I pull the trigger for slide rack, then letting it go, it works.

Sounds like a trigger spring issue, possibly not installed correctly (or damaged). Had it happen before on a G48 that I took apart and cleaned, didn't situate the cruciform properly under the lip of the bar that compresses the spring.

My first thought is to make sure the front tab on the trigger bar is UNDER the trigger spring.
Then make sure the spring and retainer havn't shifted and cocked the spring sideways, rare but can be done.

I would check if the trigger bar is properly placed and engaged with the trigger spring as pictured below. (See where the red arrow is pointing.)

I will look - if it's wrong, it came from the factory which didn't occur because I've had it for years trouble free. Never did anything more than field strip until today. I'm going to inspect the trigger spring. Thank you.

Check to see that the connector is flat up against the trigger housing.

The story is already changing.
The first post said the OP detail stripped the frame.
Now in Post 5, the OP said it must have come from the factory wrong.

My first thought was also the trigger bar not re-installed into the trigger spring hook.
It's OK if admitting a reassembly mistake was made.
I know I've made several/various mistakes over the years, especially with Glocks, as I work on those more than with other brands.

Could it be something else? Sure, but do let us know so we can all learn.

 

[Uncle Don]

Actually, I didn't suggest that it came from the factory wrong, I was being facisous. My point is that it worked fine for so long (meaning it was right) and now displays the symptom. I think I also said that I had never taken it apart beyond field stripping until it displayed the issue.

The connector is tight. I'm just going to take it to blue label dealer it came from and see if he can see anything. Thank you all very much for your advise. I'll follow up with the result.

Thanks, I learned something today. I have had a G19 gen 4 for about 8 years, recently I bought a G44 and did a 25 cents trigger job and changed to a 3.5 lb connector and the trigger was behaving strange. After seeing this I disassembled it again and the cruciform wasn't under the trigger spring. Not being familiar with the gen 5 I assumed it was the same as the gen 4.

I would put money on GlockyQ having quickly diagnosed your problem. Have you checked your trigger mechanism against the photo he posted?

 

[fastbolt]

As others have asked, did you to secure the front of the TB's cruciform into the upper lip of the trigger spring bearing?

Did you disassemble the Trigger Mech Housing? Did you fail to replace the plastic trigger spring rod inside the spring in the correct orientation ('ramp' bevel facing upwards), and position it properly in the front of the metal bearing (twisting the beveled tip to be held by the bearing), and then slide the tip of the trigger spring rod downwards until it reached the lower slot in the Trigger Mech Housing, snapping it in place?

The trigger spring assembly has a definite proper orientation for assembly and installation in the Trigger Mech Housing, and then the front of the cruciform must be captured under the lip of the top of the bearing.

It's the prudent thing to do to take it to check it to be inspected by an armorer. The Gen5 Trigger Mech housing and spring assembly are a different beast than the earlier ones.

The striker spring!

That's the problem. I'll get that done - the photo explains everything. My question however is how did this symptom appear when the frame had never been disassembled prior to my thinking the problem came from being dirty? Anyway, thank you for posting such a good photo.

 

[GlockyQ]

OP, @fastbolt makes an excellent point and provides good information about how things must properly be oriented and then positioned inside the TMH. Here is another photo to supplement his information:

Now, it is highly unlikely that the cruciform of the trigger bar came disengaged from the upper lip of the trigger spring bearing by itself or without anyone having disassembled the trigger mechanism…. However, IF it turns out to be case, it is a good idea to check if the “polymer strut” inside the trigger spring is broken or somehow damaged.

It seems crazy to me too. I've never had or seen a Glock where something came "disengaged" without detail disassembly and I'm the only owner. No aftermarket parts.

Based on the photo, it is now fixed and re-sets at 100%. Next time I'm around a current armor, I'll point this out so they can focus on that first. Thank you and all who replied.

So what was it. Was the TB not engaged in the cruciform or something else?

 

[Uncle Don]

Correct, the front of the TB was not under the lip on the trigger spring assembly and just sitting on top of it. How it came out is still a mystery to me.

 

[Uncle Don]

Double post, sorry.

You might ask the armorer to inspect and confirm the proper assembly and installation of the trigger spring assembly in the trigger mech housing. Sometimes a simple assembly mistake can make it out the doors of a company, including a gun maker.

I've seen a few examples of pistol magazines pulled from a large box of factory mags (received by my former agency) which had been assembled with the mag springs installed either upside down and/or backwards ... and magazines are pretty simple to assemble.
