As advertised
I installed this spring kit with the M*CARBO trigger and it has significant less trigger pull and smooth. I haven’t tried it in the range and I am concerned about light strikes. But, judging by the reviews, I think it should be okay. Impressive Customer Service.
Fine product - Not that easy to fit
The springs are fine. Unless you are an octopus, you don't have enough hands to fit them. The Sig P365 has a high number of minute parts that all leap off the fire control mechanism as you handle it. It took me several hours to eventually get it back together. Have 40 years engineering experience and wondered at times if I would end up buying a replacement FCM. The striker body is plastic with a bendable tab to release it. The aft end of the body is a tight fit in the sliding rear cover, requiring considerable force to release it, whilst mangling the back of the striker body out of shape. If you don't have a high degree of engineering common sense and appreciation coupled with infinite patience, take it to a gun smith. If you do decide to do it, the long, detailed video is absolutely essential. Be sure to photograph from every angle before starting, and at each major stage.
Best 20 Bucks I've Ever Spent
I replaced the springs when I did the flat trigger upgrade but there was only one trigger at my local gun shop so I did the springs on both guns. The factory trigger actually became halfway decent with this kit. So if you only have 20 bucks you can't go wrong purchasing this spring kit. But I do have to recommend you get the Flat Trigger as well but that's for another review.
trigger springs work well
I'm not sure why anyone would want a lighter spring on the striker pin, so I didn't install this. The other two springs were installed and worked find.
Great upgrades @!
I have been carrying my o365 for years as a bone stock pistol. I decided to do some upgrading so I purchased the flat short stroke flat trigger, and the spring pack. Easy enough installation, and the results are outstanding. I've been pretty handy with this edc but now after the upgrade is easy better. 10 dot 95 percent of the time at 15 yards, grouping led than 3 inches.. just wow!! Consistent break point after the takeup, very little/ almost no overtravel.
Looks good too. This is a definite recommend. Thanoverrated.

Just do it
Installing this kit with the flat trigger led to a whole crap moment of no more crunchy factory trigger and hello to something that feels like quality
Great Produce!!!
Great inexpensive upgrade. Do it!
Good products with a good installation video library. Complete spring and "Short Stroke" trigger replacement.
Replaced all springs along with the stock trigger on my P365X Macro. This is my first handgun, along with a Canik TP9 SFX. I successfully changed out all parts with very little hassle, although I did disassemble the FCU back to step 1 after I ran into dificulty with the takedown lever. This was simply to take advantage of an opportunity to really nail down the inner workings of the unit more than any real problem. Glad I did. Anyway, the shank tool definitely made the process a LOT easier, and puts much less wear on the spring than needle nose pliers would have.
Will this spring kit work with the P365 AXG?

Will this trigger kit work on the CA model 365's?
I own an XMacro, just got the kit today, and the video shows a completely different end cap assembly than the XMacro, so now I am stuck and cant install this, because there isn't a space to push the striker ring down and I don't want to mess my gun up. What gives, and why didn't anyone mention that Xmacros aren't the same?!
Try SigGuy on YouTube. Best videos of they're. Super clear videos and great explanations including what could happen and shortcuts.
While I found the somewhat obscure video in question Blythe same evening before the other reply to my question, it’s stilll torques me that MCarbo wouldn’t take the time to make some sort of small note somewhere on the page or in the notes of the installation video (not saying you’d have to reshoot it) that would make people aware that ALL NEW. 365s ship with a slide striker spring collar that prevents the end cap from being removed in the manner shown on the video.
This isn’t some small detail and should be addressed considering you’re emphasizing the ease of the DYI aspect of this.
To MCarbo,
Guys this is a failure, and I’m surprised I have to address this, make some small notation or warning statement saying that all newer models can’t be disassembled in this manner.

There are other videos on Youtube that show the other end cap removal. You have to deform the plastic tab and push it to the left and down to remove the end cap. Just do a little more research, you'll find it.

Would *YOU* hesitate to install this " MCARBO spring kit " with the "MCARBO SHORT STROKE FLAT TRIGGER" on your everyday carry gun.
rbdjr August 19, 2023 11:36 AM
I can confirm; I have standard P365 (with M*CARBO flat trigger) and while I love the feel of the lighter trigger spring kit, I too am getting much higher rate of lighter/failed striker hits on certain ammo. NOT COOL for an EDC. I’m going to have to go back to stock striker spring and just enjoy the flat trigger and whatever the other two remaining springs afford me.

Well... I am getting light primer strikes on both an XL and XMacro 365 that have this spring kit, causing the round not to go bang, very bad for an EDC.
Can't 100% verify it's the new spring kit, for sure, but will soon swap back in the original spring and see if that helps.

Put it in mine - WOW great improvement!
Will your kit work with Armory Craft's Positive Reset Trigger Return / Trigger Bar Spring? Their full kit is a 4 piece while yours is just 3. I keep hearing about your springs so, I'm swapping my Armory Craft - P365 Ultimate Master Spring Tuning Kit with yours to see what the rave is about.

Will the spring kit also work on the p365xl spectre comp?
Why no sanding/ polishing on this spring set change? Will polishing reduce the trigger pull a little more?
Thanks brothers!!

Will this kit work on the P365XL, I the FCU ’s are the same besides the flat trigger
Thanks
Yes it will, our kit has been tested on all 365 models outside the Macro since that is a relatively new model.
Do you have an installation video for p365-380 without the manual safety?
the installation video on the website is without a manual safety.

the installation video on the website is without a manual safety.
What would be the effect if I installed just the striker springs? I am looking to reduce the trigger pull but also smooth it out.
By Just changing a spring you won't be getting the full benefits from the kit so you won't see much reduction
How much will this lower the pull weight WITHOUT installing the striker spring?
if you install the other springs it should be pretty close to what we advertise. It wont be spot on however it should be with in a pound. Its hard to give an exact measurement since each firearm is different and springs usually have a + or - a pound to them.
How much harder is it to install in a p365 with external safety?
Not much harder, all you have to do is remove the safety to make it easier to complete the install.
Does this work with the P365 .380 model?
yes our spring kit works in all P365 models!
Looking to improve take up and reset WITHOUT lowering pull weight. Will a combination of your springs and stock springs do the trick? Looking at your trigger shoe as well. Thanks!
Sorry for our delayed response in the Q&A's! If you want reduced pretravel and a crisper reset without decreasing your trigger pull weight, you definitely need our Short-Stroke Flat Trigger! Here's the link to this product:
https://www.mcarbo.com/sig-sauer-p365-short-stroke-flat-trigger-upgrade.aspx
This trigger will fit and function perfectly with the stock springs, which will ensure you maintain your current pull weight, and will give you everything you are looking for.
Does this work with the P365X?
Awesome! Thank you so much for sharing this with us and other customers!

I just finished putting this kit in my Sig P365X Romeo Zero and the function test checks out find. Haven't tried it at the range yet, but will in a few days.
I don't have a trigger gauge, but I'd say it lowered the trigger pull by a couple of pounds and I didn't install the sear spring...yet.

Yes. I can confirm, this does work with P365X. Followed the video and installed the kit. There is a slight difference with the P365X where the small spring behind the sleeve on the striker does not exist with the P365X. This is not a spring that is part of this kit, but it shows up in the install video. Just want others to be aware. The pistol performed flawlessly and felt great!
