The Glock Competition Trigger Spring Kit will give your trigger a smoother, lighter, more crisp feel, reducing your trigger pull by 33%. This kit includes three different firing pin spring weights, so you can adjust your trigger pull to your exact liking. Plus, our springs are made from the finest American spring steel, so you can trust in their quality and durability.
For even better performance, we highly recommend using our Firearm Polishing Kit to polish all the internal components of your Glock. This is the best Glock trigger kit available, with more reliability than any 25 cent trigger job. You won't find a smoother, more refined trigger pull for your Glock anywhere else.
Our custom Glock Trigger Kit includes accurately calibrated spring weights that deliver consistent force through the entire compression and release cycle, giving you a light, refined trigger pull without sacrificing the reliability of your pistol's Safe Action system. The Extra Power 6lb Trigger Spring is 28% more powerful than stock, reducing felt trigger pull and providing increased tension for a faster trigger reset.
The M*CARBO Glock Trigger Spring Kit gives your Glock increased power for a stronger primer hit/strike. You can change specific springs to improve a particular aspect of the trigger pull, or do a complete upgrade for the best performance. This kit works with all Gen 1-4 or Gen 5 options, including the Glock 19 Trigger Kit or Glock 17 Trigger Kit.
Watch our step-by-step Glock Trigger Spring Install video for easy-to-follow instructions on how to install your new Glock trigger kit. This is the ultimate aftermarket Glock trigger upgrade for available Glock drop-in trigger kits, and it's better than any 25 cent trigger job.

Worked so well I bought second kit
I installed this in my Gen 5 Glock 17 which already felt pretty good out of the box. After inspecting the internals I opted not to sand or polish anything and just installed the springs. The improvement was immediate and the trigger pull is much smoother now. I was so impressed I bought I second kit for my other gen 5 Glock
Glock springs
I used the 4lb spring and all other springs. Easy installation, nice instruction video.
The trigger smoothed up and had a predictable break and reset while firing the Glock. Works great.
I'm very satisfied with all my mcarbo purchases. This is not the first time or last when my triggers need upgrade I trust mcarbo ....
glock 17 gen 5 spring kit
spring kit works great easy install if you're looking for an inexpensive trigger reduction can't
go wrong with this spring kit
Disappointed
Ordered for gen 5 only received firing pin spring Sent several emails and called haven’t got response in 3 weeks don’t know what’s with this company.
Glock 43x
Overall the spring kit does the intended job, however I had to use the factory striker spring in order to retain the safety of the trigger dingus functionality. With the softer springs the trigger wouldn't return forward enough to reset the dingus. I emailed about the issue over a week ago and have yet to hear anything back, will update my review once I've heard back.
Easy install
Parts arrived quickly, install videos were helpful. Once the spring kit was installed the trigger was much lighter and smoother. Big bang for the buck upgrade. Go for the polishing kit as well while you're at it.
Glock Spring Kit
MCarbo is fantastic and makes superb products. Could'nt be happier with this upgrade!!
What gen is the Glock 19X?
Will this work with a 43x?
Can you add this spring kit to the glock performance trigger?
What kind of results should I expect from a Glock 26 that already has the OEM minus disconnector installed (no other mods)?
Which pound firing pin spring should i use for my Glock 30 .45 Auto? Thank you guys for your time!
Will it work in the g42 as well?
Will this work with gen 5 Glock 17
Which kit works with a Glock 26? Thanks
I HAVE INSTALLED A NUMBER OF YOUR GEN 1-4 TRIGGER SPRING KITS BUT I NOW HAVE A GEN 5 MODEL 45 AND IT SEEMS AS THOUGH THERE ARE NOT AS MANY PINS TO REMOVE AND ONE OF THE SMALLER SPRINGS IN THIS KIT SEEMS DIFFERENT FROM THE GEN 1-4 KIT. YOUR VIDEOS ARE GREAT!!! WILL THERE BE ONE COMING TO SHOW THE DIFFERENCE BETWEEN GEN 1-4 AND THE GEN 5 KIT INSTALLATION? THANKS FOR WHAT YOU DO!!
I already purchased the gen. 5 spring kit, and just put a bid on a "Glock Performance Trigger Flat Faced 70272 for Gen 5 Glocks" kit. It seems to me like they are as the glock kit does not seem to include any kind of spring, but I just want to make sure. Thanks!
Which kit works with Glock 41
Will the gen5 kit work in the G48?
Yes! Just make sure to get the Gen 5 kit.
Yes.YOU WILL NEED TO SELECT THE GEN 5 KIT
I had heard that the Glock 19X was a generation 4 so I ordered that kit without looking at the lower compared to the G23 Gen 3 I have. Are the trigger springs and firing pin safety spring interchangeable between the two kits?
The Gen 5 kit has a different Trigger Spring that will not fit on earlier Gens. The firing pin safety and firing pin springs are the same between both kits.
Will the Gen5 work on the slimline G43X MOS?
December 26, 2022 12:06 PM
Yes! Just make sure to get the Gen 5 kit.
I just bought a Glock 23 Gen 5. Can I assume the Glock gen 5 kit will work ok on it?
I bought the kit for my Glock 19 gen 5, but there is no video or written instructions for the trigger spring (disassembly/reassembly/polishing of the lower). Can I expect to see something to remedy any time soon?
The slide mod was a piece of cake thanks to the gen 4 video.
