Got the trigger minus the springs. Watched the mcarbo installation video and Bam! Trigger is nice even without upgraded springs which i may do later. The ordering and shipping was quick and easy.

Awesome Trigger!

If you are on the fence about buying this trigger then don’t be because it’s well worth replacing the factory trigger. The reviews speak for themselves along with the YouTube videos that are out there on this trigger. Absolutely love this trigger by MCARBO.

Awesome when it works

I installed the mcarbo trigger on my XMacro and noticed that it slightly lifted the sear to where the slide wont go back on. I managed to get the slide on by removing the back plate, installing the slide (w/o the backplate), locking the slide back, then reinstalling the backplate. However, I had to do this action every time I took off the slide. The trigger itself was wonderful! Short pull, and none of the grinding feeling from the stock trigger. Ultimately I had to take it off due to me noticing that the slightly lifted sear tab was creating a groove on the inside of my slide as well as grinding the sear down a bit..

Best

If there’s one mod for your p365 to do then this is it. This trigger with the spring kit is not only well worth it but also borders on necessary. Say goodbye spongy trigger and hello to the crisp feel of accuracy. Well done MCarbo.

Best Flat trigger for P365

Hey Brothers,

Recieved, installed, adjusted and what an awesome trigger. Nice and crisp break and reset, perfect amount of travel. Far superior to the OE Sig Flat Trigger. I have every upgrade you make for the P365 in my Sig. You guys are the best, keep up the good work!

Best P365 Trigger

I have now tried about 6 different P365 triggers. This one is by far the best P365 trigger I have tried. It just feels great throughout the trigger press and reset. And no trigger bite.

Best P365 trigger on the market.

Big thanks to Ken at MCARBO for getting me into this trigger. It is such a vast improvement over the stock part that it is almost like having a new pistol. I just finished putting 500 rounds through with it and it is amazing. Buy with confidence!

Best Trigger for ALL P365 guns 🔥🔥🔥

A major Game Changer.. Best decision I've made. Fell in love all over again with my P365XL with this trigger... Only 3 1/2 lbs 💕 makes shooting more fun.. If you own a Sig you must upgrade to this trigger.. Highly recommend this 🔥🔥🔥

Best trigger I have installed in my P365

I have tried the OEM curved, OEM flat, a PSP hybrid, and finally this flat trigger in my P365's. It is my favorite due to the true flat shape and feel for equivalent pressure, pretty much anywhere you press it. Also, the adjustable reset is nice and limits over travel. I now have one of these in each of my P365's (3 so far) and my dad had me install one in this EDC P365.

Best trigger out there!

WOW! Trigger was better than what I was expecting! Love the ability to adjust the overtravel. You won't be disappointed with this trigger, in fact you may be surprised how it helps improve your shooting. Also like the targets, cool idea. Thanks for being a solid company who is on top of their game. Next up, the Titanium firing pin.

This is by far the best trigger upgrade. The trigger is adjustable, the finish is smooth, the resting angle is better and definitely feels more solid. Everyone needs one of these.

Best way to go

Great trigger! Currently have 900+rnds on it. The increased control & minimized shot groups is phenomenal. Have been outshooting full size glocks, and p320’s all day.

Got to test out a stock 365 next too it and we all agreed there is absolutely no comparison.

Negatives: the instruction video is amazing but be prepared to mess up and it take you bare minimum 2 hours to install, even if your experienced! I’ve done quite a bit of my own gun smithing and this is the 2nd hardest task I’ve done next to my DD MK18 adj. gas block.

Also I usually ask for custom product stickers to slap on my safe to help rep company’s I use, but just assumed they would throw one in.. they don’t so ask. 3rd world problems I know! 🤷🏼??? for the hassle install we deserve at least a sticker. 😂

Great product! Absolute best trigger for the 365! Been recommending it to all my friends like I work for the company since install.

If you’re on the fence about getting it, just do it! You won’t be sorry.

Lastly, the aftermarket “light” spring that’s in the video is sold separately from the trigger and for the price just add it to the cart.

Wish I had. 👍🏻💪🏻🇺🇸🇺🇸

Better than stock

I installed this on a 2025 P365 XL along with the spring kit. I got the red trigger, should of stuck with black as it wasn't the best cerakote job I've seen. Only other issue was set screw hole was not threaded on trigger. I thought perhaps the cerakote was coating the treads, but could not feel threads with a micro pick. I took it my gunsmith who verified, no threads and he drilled and tapped it to M2X.4 and used a matching set screw. No other issues, installation was fairly straight forward, video instructions are very good.



Overall, much happier with Mcarbo than with the stock trigger, pull went from 6 lbs+ to 3.8-4.2 lbs depending on trigger gauge placement. I would but it again.

better than the original

It is a great upgrade. Much less travel. This is a must have if you own a p365. Trigger is a bit hard to install, but YouTube has great videos. I recommend the Sig Guy video on installing MCarbo for p365. It doesn't require dismantling the entire FCU.
