Glock Trigger Mods

About 15 or more years ago I lent my G17 to a friend who is in the DOC. He ended up having their armorer do a little work to it. He installed a Glock extended mag & slide release, stainless steel guide rod, Wolff recoil spring, and did something with the trigger - possibly installing a Wolff trigger spring and it looks like he polished the surfaces up.

All I know is that when I got it back the trigger was a little stiffer to pull but all of the squishy feeling was gone. I put several thousand rounds through it over the years and never had any issues.

I want to see if I can get the trigger better so I read several posts on her regarding Glock triggers and it seems like using the 3.5# connector with a NY1 trigger spring seems to be the most widely used.

I picked up a Glock 3.5# connector and a NY1 trigger spring.

With the 3.5# connector and the standard type spring installed -

  • light pull, maybe a little too light
  • really shitty reset

With the 3.5# connector and the NY1 trigger spring install -

  • harder pull
  • really good reset
  • pretty damn close to what it felt like with the 5# connector and standard type spring

What I am looking for is something that will give me a heavier pull than the just the 3.5# connector but not as much as the 3.5# connector & NY1 spring AND provide a good, solid reset.

Am I chasing the impossible or does someone have a tried and true combo that will get me there?

Thanks.

Disclaimer - I have not had a chance to fire my pistol with these parts as of yet, just done dry firing exercises. For the reset I hold the trigger down after firing, rack the slide, and slowly release the trigger and see how it feels.

I’ve heard of a few guys that clip off a couple of coils on their NY1 spring, or completely remove the spring all together.

I personally like the factory 3.5lb with standard trigger spring. :slight_smile:

Tagged! I’ve been wrestling with this too .

Sounds like you may have had a 3.5lb Connector with NY1 Trigger that had its spring removed. I personally like the basich combination of 3.5lb Connector and NY1 Spring. I find that while it “seems” to heavy it’s actually a nice consistant 5lb pull making me much more accurate when shooting fast.

Try removing the inner coil from the Green NY1 Spring w/ the 3.5lb. Connector.

Results: Firm “Positive” First Shot Take Up, but with a Crisp Break & Short Reset. After the first shot, shooting from reset to reset is Short, Crisp, & Fast.

Thousand & Thousands of rounds from Various Small/Large Frame Glocks without one hiccup. Love this combo for Carry, Training, HD. No worries about breaking a coil trigger return spring.

That’s what mine currently has.

Glock factory ‘’-‘’ 3.5 lbs. connector + NY1 spring with inner coil removed.

I just switched from 3.5# connector to the 3.5# plus the NY1(with spring intact). I am liking the feel of everything so far. I like the constant weight of the pull, it is not “stagey” at all. It is also a factory approved configuration, if that is of any value to your situation.

ETA: After a few IDPA matches I switched to the regular connector plus NY1. I am shooting that one better.

Have you tried just swapping out springs and leaving the connector stock? I think Wolff sells a pack of springs reduced power striker, increased power trigger… You can mix and match. Just be sure to read and obey the warnings on which combinations to stay away from. You can also try different brands of connectors. I tried a couple of different ones till I found one that felt good to me. Good news is that the springs and connectors are cheap so it’s not like you’re flushing huge $$ down the toilet till you find what you like.

FWIW, Wolff does not recommend using ANY competition springs for duty/HD/CCW handguns.

I took out my comp trigger spring after one of the engineers told me on the phone they will not recommend them since they break more frequently than Glock standard trigger springs.

After reading the posts here and doing a little poking around on the net I now have the 3.5# connector with NY1 trigger spring with the coil removed.

The pull is not as hard as with the coil spring and the reset is great.

Wouldn’t mind something a little closer to the 3.5# connector with the standard spring installed.

I was wondering about filing the rounded end of the NY trigger spring where it contacts the connector.

I usually run a 3.5 and standard spring with a polish job on almost all of my Glocks.

The below video is part 1. I do an extended slide stop, 4.5 connector, keep the standard spring and do a polish job. The other parts of the series are on my channel.

Glock Trigger Job Part 1

While I can live with the standard Glock trigger, since going to the Apex Duty Kits on the M&P’s, I now prefer to run the Glock OEM (-) connector and stock trigger return spring in order for the Glock triggers to feel more like the M&P/Apex ones.

Excellent set of videos by the way. A couple of months ago I used your videos as a guideline and had great results with my 19.

The (-) connector and NY1 spring with coil removed plus the method of polishing you show makes for a truly excellent ~4.5 trigger pull.

I like the pull with the 3.5# connector and stock spring but the reset really sucks.

Nobody’s gonna wanna hear this but a Gen 4 gun with a 3.5 connector delivers something like what it sounds like your describing. :smiley: That’s what I’ve got in my Gen 4 17 and I like it mucho.

Is the Gen 4 trigger bar different from the earlier generations?

Try Vanek Custom

EZGoing - Yes it’s trigger bar has this pimple like bump like a G37 or newer G21 trigger bar. And the trigger spring has been moved to a different angle to make it more reliably longer lasting. It’s been explained to me that these changes are responsible for the slightly heavier but cleaner breaking trigger on Gen 4s (and yet harder reset). When combined with a 3.5 connector it’s not as light as a Gen 3 with a 3.5 connector but has less mush than the Gen 3 with 3.5 - in my experience anyway.

Thanks and I am glad it worked out well. The polish job really cleans up that standard Glock gritty or crunchy trigger feel.

Just to update this post, I played around with the minus connector and NY1 spring and did not find what I was looking for.

After reading the Glock article on Military Times I ordered a “dot” connector designed for the Gen 4. It finally arrived on Friday.

My current setup in my 3rd Gen G19 is:

  • Smooth G17 trigger
  • Glock “dot” connector
  • Factory Glock coil type trigger spring
  • Wolff reduced power firing pin safety spring
  • Wolff increased power firing pin spring

All I have done is dry fire the pistol so far but I will say this is the best setup I have tried thus far. All that squishy dead space is gone, the trigger is “crisper” than before with a slightly reduced pull compared to the original trigger. Reset is solid too.

For anyone looking to improve the trigger in their Gen 3 or earlier Glock pistol I would say to pick up a “dot” connector and give it a try.
