I personally like the feel of “minus” connector + NY1 trigger spring combination in my G19 and G26. (Perhaps that’s because I’m so used to it.) The original trigger spring that came in my G19 broke while dry-firing soon after I acquired the gun. I then installed a “minus” connector and NY1 trigger spring. I haven’t had any issue with my G19 for over two decades. The only part that ever broke besides the original trigger spring was the original extractor. ...

I would love to try it they are always sold out when I order.

The stock spring makes the trigger pull lighter by actually assisting in the pull, the N.Y. style adds resistance to the pull, so other parts changes would be needed even with a very light NY spring.
Glock actually did do this though, it’s called the Gen 5 :cheers:

Done, thanks.
Ok, just back from my second range trip of the day, and it proved interesting.
Ran 200 rounds thru my carry gun with its new trigger setup and I’ll be keeping it this way. My second target of the day didn’t look a whole lot different them my first. Maybe my groups opened up a bit but I’ve no doubt that will settle back in.
I kinda liked the way it is now just one smooth pull to fire instead of the “ two stage” stacking feel of the stock pull. I will of course need to see how that plays out when working out of a holster.
The reset is a definite plus with this setup. It is almost forceful in that you can feel it wanting to drive your finger forward. Next week I’ll get to the outdoor range and run it against the clock head to head with one of my others and see what the splits look like.
I don’t have a way to measure trigger pull so I have to go from feel. This seems just a bit heavier but that may very well be because it’s starts so early instead of stacking. I did have to pay attention to my support hand for the first couple mags to apply constant pressure as I wanted to drift left a bit but by the third mag it was just natural.
All in all I’m pretty pleased. I don’t know that I’d call this a better trigger but to me it’s sure no worse and honestly it feels more secure without all that loose first part of the pull when reholstering, but of course that’s just one guys impression.
I’ll be keeping this setup for a while and run a thousand or so rounds thru it before deciding if the others should be changed as well but for now it stays.

YEP380 - Thanks' for the Brownells free shipping heads up; ordered a couple of different springs. It's a PIA when shipping is more than the parts.

Actually, the GLOCK will work without the trigger return spring. Yes, handling is slightly different, but it will still work fine. This was demonstrated to us in the most recent armorer’s class.
This is a great combo. I used to use the NY1 with standard connector until we were shown in the most recent armorer’s class that the pistol will work fine without any trigger spring at all.

As WW points out, the coil trigger spring is the OPPOSITE of a trigger reset or trigger return spring. It exerts its force away from the direction that would pull the trigger back forward. The only trigger return spring in a Glock is the firing pin spring.
It's surprising how almost all of the big-name U-toob celebrities get this 100-percent wrong (including Hickok45 and Chris Bartocci). It's not a trivial point, because this error is *exactly* analogous to confusing an automobile's BRAKE with its ACCELERATOR. One can take no pride in that level of misunderstanding the basic fundamentals of how a Glock works..
The NY1 trigger spring exerts NO rearward pull on the trigger bar, so removing the rearward spring force on the trigger bar that the normal coil TS exerts will just by itself raise the required trigger pull above the original nominal 5.5-lbf by about 1.5-lbf. Any further desired increase in trigger pull force is obtained by the NY1 spring pushing its polymer upper surface against the bottom of the trigger bar cruciform. Use of a stronger coil spring in the NY-type TS will create the higher required pull of the NY2 TS. So, as has been pointed out earlier in this thread, it is *impossible* to get a nominal 5.5-lbf pull by using even a custom NY-style TS.

(Part of what follows has already been presented by others in this thread.)
Glock OEM Part Design Improvements
To Reduce Coil Trigger Spring Failure
1. In 2010, the new Gen4 pistols implemented:
a. A new coil trigger spring attachment point on the Trigger with Trigger Bar that reduces the stress on the forward TS hook to make hook failure less likely.
b. A new coil trigger spring attachment point on the Trigger Mechanism Housing that reduces the stress on the rear TS hook to make hook failure less likely.
2. By 2011, the Gen4 improvements were implemented on new Gen3 TWTB and TMH parts and pistols. Backfitting these improvements in older Gen3 and earlier pistols only requires replacing the TWTB and TMH with CURRENT Gen3 parts, and installing a new coil TS.
The coil trigger spring seems to fail most often at the rear hook with the pre-2010 design.
I would not waste time worrying about coil TS hook failure if I were using a Gen4 pistol, or a Gen3 or earlier pistol with the improved Gen3 TWTB and TMH.
The TMH for Gen5/M/G42/G43 incorporates an integral coil TS that compresses and has no hooks. TS spring failure should be very very very rare.

Hmmm... the trigger spring I broke was in the middle of a IDPA match. The solution was to rack the slide, and I finished the match with a few unplanned slide manipulations.
I then replaced all "5.5 coiled springs" with the NY1 spring just to keep life simple and standardized. Really like the positive feedback from the NY1 spring too!

Thanks Mike, always appreciate your insight!
Thank you for catching that. I have no idea why I typed “ trigger reset spring” as I know that’s not what it is. I correctly called it just the trigger spring from that point on and in other posts...no idea where that came from.FWIW, the Trigger Spring isn't the Trigger Reset Spring. It actually works against the reset process. The firing pin spring is what resets the trigger.
The Trigger Spring is the most frequent part on the Glock to break. Keep one and a punch in your range bag and you are covered for six sigma events when it comes to Glock failures. Or just change all your springs at say 20K round intervals.

Agreed. Sorry for the “ mis-typing”.

I think we all do the misnomer thing when we are slamming along typing in a stream of thought, less focused on names than what happened. When I see it, I just point it out so the less informed maybe get a more complete picture. Glad you got it sorted.

Erroneously calling the Trigger Spring a "Trigger Return/Reset Spring" is a no never mind issue from people who do not claim to be Glock experts. But many people with well-known public presence and reputation in Glock User World...in U-toob videos, website articles, and gun magazines...make that error over and over and over. Conclusion: The "expert" does NOT understand what the Glock coil trigger spring does.
