Glock 19 Hard trigger fix question 

3x Certified Glock Armorer, worked on hundres of guns for a municipal police dept. This is not uncommon in Gen 3's. Replace the trigger bar. There will be some sort of deviation in it from manufacuturer spec that will be completely un noticible to the naked eye. The symptom is that the trigger will feel like its stacking heavier and heavier towards the rear of the trigger pull. It gets progressively heavier. It will feel like 15-20 lbs at some point before it finally wont break at the end of the pull.

So what I found was that the connector has a sweet spot where it likes to be if its too far in your trigger wont reset or too light of a reset. And if it too far out your trigger bar hangs up on the connector causing hard trigger pull. Take out your connector and bend it in a bit with a pliers and insert it back into place. then bend it out slightly little by little till your trigger is crisp and functioning perfectly. nice crisp trigger pull and reset.

Check your firing pin channel liner, I had a same issue with little more problem of slide. My Glock 19 Gen 4 had a very light & smooth trigger pull, but when I sent my slide for polishing as it had lots of wear & tear marks after a long use, when it came back and I roe-assembled the slide on frame, the trigger was almost freezed, I had to use another finger of my support hand to give force to my strong hand's trigger finger to pull it. You can say, it was around 50 pounds heavy trigger, which I was unable to pull. Then after inspection it deeply, I found the channel liner issue, that was stopping firing pin spring to work properly. I just changed the channel liner and the problem was fixed. Now I have again a smooth & light trigger pull.

Would be nice if you showed the internals, slide and receiver. I am a Glock armorer, the first thing I would check is the firing pin safety, remove it and clean. Could be trash under the safety in the spring. Then the connector. Please make another video showing the internals.

Hey John, I had the same problem come up this weekend on a Nomad build. New trigger kit, smooth install. Oiled all the sexy bits. After 30 or so pulls it started getting tighter and tighter, you could feel the binding. Pulled it apart so many times I feel like I should be teaching a class. Finally swapped connector (looked identical but it was a gen 4 to a gen 5) and the problem has gonna away. Did that fix your issue also?

Thanks for the video, an thanks to those who replied because yall helped me, I did a polish job an guess I pushed the connector in with to much force resulting in a very hard trigger pull, I bent the connector out a little an now I'm back to a 5 1/2 to 5 pd trigger pull, so much better

So there’s two main types of engagement when it comes to your trigger pull. The cruciform engaged with the striker and your connector engaged with the trigger bar. If your connectors angle is wrong or off that can cause a reset issue (that Audible click you hear) is the connector slipping off the trigger bar. Simultaneously the cruciform dropping off the striker..and then as the slide recoils back that resets everything else in place for the next shot.. now seems to me without seeing it that it in fact is a connector issue. Because off top it’s looking like you need to apply more pressure than necessary to get the trigger bar to engage the connector and reset. OR! A trigger housing spring issue. When installed the spring has to be vertical with the cruciform if crooked can cause issues. Or could be just an issue with the spring itself So check into all those components too and there’s vid to show you how to do your safety checks and assembly an all so make sure your doing things in proper order . And another thing it mostlikely is not a cleaning issue glocks have incredible reliability in even the worst conditions. But still keep up with common maintenance but still not the issue your dealing with…so I hope this is a little more helpful maybe to basically and quickly explain what’s happening inside when your pulling on your trigger.

Did you ever get it fixed? I’m having the same exact problem with two different triggers

No idea John. Sounds like some tolerances are off. I’ve got a bone stock Gen 3 19 with a good trigger so I never messed with it. Hopefully someone will be able to help you out.👍🏻

If you haven’t fixed this yet, try adjusting your connectors bend angle. It probably needs to come away from the housing a bit. Just look up how to adjust, I had this same issue then tried that, I figure the spring gets compressed over time and caused the issue.

Quick question, was it harder to rack also?

Did you ever try checking your trigger bar housing pin to make sure that it was seated correctly

Any resolve to this issue? Same problem I’m not experiencing with my gen 5. Was one of the best triggers I’ve had in a stock Glock and now this

What’s the trigger pull weight??? Get a gauge… stock is 5 lbs give or take … but it seems nice and christ to me …

I don't own a Glock the only thing I can think of is trash or junk down in the interior of the trigger assembly. Just my thoughts on that.

You fix it, I have this same issue ?

Remove the upper from the lower excessively this will solve the problem

Looks like a sweet break to me

What? The sacred Glock has issues?

I wish I can help sorry I don’t own a Glock 🤷‍♂️

I just had this happen to me. felt like if i pulled to hard i would break it and the trigger would not drop. this was right after a 25 cent polish. The connector had been push toward the housing to much. using the old reverse trick, I pulled out the connector and installed it backward in the housing and lifted it 3 times gently ( the bend will be away from housing) re-installed and done. here's a vid. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Z6BK2bglB4I.html Best of luck
