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!!
my choice
this is my 25th build using Mcarbo Glock springs, either i order them or I heavily promote the parts for customers to purchase and I install them. these spring kits are the best only spring kit I will use and recommend to customers

Works on PSA Dagger
For liability reasons, both PSA and MCARBO do not recommend this spring kit for the Dagger but I decided to try it out anyway since the Dagger is basically an exact clone of the glock gen 3. Low and behold the MCARBO springs were an exact match in fitment as the Dagger OEM springs. I did a function test before going to the range, dry fired and made sure the trigger reset and it did. I took it to the range but only had time for a box of ammo of which it ran flawlessly and a noticeable and pleasant upgrade on the trigger. I did not polish anything, only upgraded the springs using the 4lb firing pin spring and it dropped an estimated pound or pound and a half. I do not have a trigger gauge but based off my other guns I would guess it's now a 5lb or possibly 4.5lb trigger. I'm really happy with the upgrade. I was able to do a few rapid fire drills and keep a decent grouping at 10 yards. I really just wanted to slightly improve the OEM trigger and did not want to shell out $200 for a drop in trigger which is what I got. Love MCARBO and have bought their kits for my SKS and my Rossi RS22. Both of which were manageable upgrades with their instruction videos. Great company and well worth the time for a rather cheap yet reliable and functional upgrade for your triggers.
CZ SP-01 Spring Kit and Polishing
I've been shooting over 35 years. I shot competition in the early 90's with a CZ and a Glock 17. I have recently gotten back into shooting matches again. I saw a slightly used CZ-SP01 for sale and bought it, but the dbl. action was way too heavy (I was used to my Glock 17 and 34). I read some of the claims by M-Carbo and decided , why not? I sent off the gun and when I received it back , in a word , "unbelievable!!!" The trigger is smooth as glass, and the trigger pull is half of the weight or more . The gunsmith who called me to tell me the gun was on its way, told me that the single action was very light. Well , that doesnt come close to again, the smoothness or crisp light trigger pull and release of the hammer. Im beyond happy and if I get another CZ I will be sending it off to M-Carbo again . I cant thank them enough for the quality and workmanship that they put into my gun. well worth the money.
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.

December 1, 2021 10:22 AM
