I a noticing a problem, often, where the trigger bar functions nicely, but does not drop down to release the sear. this is mostly seen on the G19 and G17 builds. A majority of the trigger parts are from 80P builder and Others. Any thoughts why the trigger bar would not drop as it moves backward in the trigger housing? This manifests as a failure of the firing pin to release from the sear. Do I just need to get Glock factory parts?

Sounds like the connector bar is too far in. The "bird beak" of the trigger bar is missing the connector "ear."
 
Also, aftermarket trigger housings have wildly varying dimensions and connector angles. You can't see the difference most of time but break out your calipers and do some measurements of the housing sizes and measure the connector angles. It's eye opening. That's why I only recommend Glock OEM trigger housings.
 
Speed in doing maintenance is not one of my metrics. I take my time when I'm fixing, cleaning or upgrading guns.

Pull a gun on me ... there will be a blur and a loud bang in under two seconds. :) I can be very fast at some things.

I once gave a girl named Jeannie the best 90 seconds of her life in the dugout after a game. :love::whistle:😜

In the frozen section or in a can. :outta here:
Bazeball was very very good to me. Next best thing to being a rock star. College ball... there were b-ball groupies. Just like Bull Durham.

I got lost for a few days there. I have tried adjusting the connector and will address it again. The video is great and I remember it from the past. After watching it I'm going through the adjustment procedure again. I have since replaced the trigger/bar/housing with Glock OEM parts (funny how most of the issues disappear with this simple change:eek:)). I can see that the problem is the trigger bar does not drop and release the sear. I have been looking at the connector and it's interaction with the end (Beak?) of the trigger bar. Once i get this figured out, I'll have a few builds complete.
 
Something is keeping the trigger bar just a bit high and engaged with the sear. I am beginning to suspect Upside
down
springs...

There is a Marinegunbuilder video regarding the trigger spring. It does have a correct orientation. The ends are different. It is also possible for the spring to slip to the side when you put the bar in the trigger housing. Happens a lot on aftermarket parts because the notch to hold it isn't deep enough.
 
I started with MGB and will have to review this video. thanks for the heads up. It would be embarrassing if I have the spring in wrong....
 
My springs are in correctly and the internals are Glock perfection OEM. With the short end plate I can see the trigger "beak" interacting just nicely with the top 'Ear' on the connector. As the trigger bar moves to the rear, the beak rides under the tab and lowers the sear; just not far enough to let go. The original engagement between the sear and firing pin is 110% or more. It sure looks like the sear on the Trigger Bar needs to be bent down just a bit. It is an Alpha Shooting Sports upper. Bending the sear down is an obvious solution, but it is making me uncomfortable. Is it less than intelligent to bend the sear tab down so you get 50-75% engagement with the firing pin?

I Have what appears to be over engagement between the sear and the firing pin; they do not release. I can watch the smooth progression of the trigger bar 'Beak' as it rides under the 'Tab' on the connector. Everything drops and the sear/firing pin are still 50 % engaged when they should have separated. Either file the firing pin down a smidgen or bend the sear down a hair. Yes, Smidgen and Hair are technical terms referring to a sort of small amount. Any thoughts out there by fellow adventurers who have done this and learned a lesson or two?
