A must have upgrade for the P365 series
The striker block is what causes the "boing" when you pull the trigger. Changing that and the sear spring will give a crisp, excellent CCW trigger while maintaining factory reliability!
That's what I do and that's my personal suggestion. I had a few hard primers/light strikes with the striker spring installed, so I switched back and had a trigger/gun that I shot better than my Canik Mete SFX Pro. The break is far crisper and it isn't too heavy...great for a CCW oriented gun.
A must have! I bought one years ago and must buy another for my newer gen slide with threaded barrel, comp, and EPS Red 6.
Just plane awesome
Once installed along with the flat milled trigger I received a solid 3.6 lbs of trigger pull and crisp trigger with no slack and minimal reset.
Great Spring Kit
These springs are a huge improvement over the factory springs.
Paired with the MCarbo P-365 trigger is a massive improvement over Sig OEM parts.
Great addition and bang for your buck with this purchase.
Great upgrade at a minimal cost.
This spring kit definitely helped smooth out the trigger to a noticeable degree. I installed it a the same time as the MCarbo Flat trigger and titanium striker. The stock trigger was ok but this worth the cost and easy to install .
Good Product Good Price
Could be better if they also came with a Trigger Reset Spring. For the same price you can get a 4 piece kit from Armory Craft. No noticeable differences between each kit. I kept the MCarbo kit in with my reset trigger from Armory Craft because of my experience with MCarbo in other firearms.
Great replacement springs and installation video
I'm not new to spring upgrades, I've used Wolff Gunsprings on many firearms in the past. I recently acquired a P365 Micro and decided to upgrade the trigger. The springs are adequately strong to perform their job reliably, but they definitely improve the felt trigger pull and reset. While installing them, I went ahead and polished the sear and mating striker surfaces using a dremel tool, small diameter felt wheels and chromium oxide paste. This only added a few minutes to the time that the project took and definitely helped as well.
Easy as it could be
The entire process was extremely easy thanks to the instructional videos. The trigger pull is great, there’s still just enough but the overall feel is great. With the factory trigger I always had that little jerk at the end that would make me pull high left, however with this kit you can squeeze right on through. Highly recommend. The only issue I had was that sig has changed the back plate removal since the video was posted. However a quick search and I found a video for that as well. It added maybe 5 minutes to my installation, no big deal.
Game Changer! (P365 X Macro Tacops)
It was a bit of a pain in the ass to install (Not M*Carbo's fault) but WELL worth it! The stock trigger is okay but a little stiff... now it's BUTTAH! This should be the first thing any new owner of a P365 should do. Couldn't be happier with my purchase. Oh... and the shipping was super quick too. :-)
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?!
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.

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!!
Does this kit work with p365x?

Thanks

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.
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!
