I really like lower weight trigger pull. I think it increases my ability to put follow up shots right on top of previous, if I am doing my job on sights and grip. It was a bear to get the trigger kit and spring kit installed on the FCU, due to some incorrect instructions, but if you watch all their install video's, you'll get it done fast. Just make sure to check their support and product page, not just their youtube channel. So far, it's been great and fully reliable.



Specifically, there is a trick on installing the takedown lever, the trigger overtravel set scerew, and the sear spring, that their website videos will tell you. I feel like the XMACRO FCU is a little different than the 365 FCU, especially in how the takedown lever is installed.

Won't fit 380ACP

I took this trigger to a gunsmith, estimated 1 hour to complete the job, 3 hours later (at $60/ hour) they couldn't get it to fit. The gunsmith was able to install it successfully in a different 9mm without issue. Customer service took slightly over 48 hours to reply, not terrible, and is currently over 24 hours on the reply email. Too bad it won't fit, as I was excited to get it installed after reading all the positive reviews.

Wonderful upgrade

I installed this flat trigger in my P365XL and it did require some hand fitting to make it go in properly and then adjust the setscrew for final trigger operation. I feel like the gun now has a better trigger pull , shorter takeup stroke and shorter reset for follow up shots that are quick and accurate. I also installed the MCarbo Titanium Striker assy to help improve overall gun performance now my P365XL is a SUPER SIG !

Works on my P365CA

My hope with this trigger was to have my trigger finger a bit further forward (towards the front of the trigger guard) when the gun fires. The reason is that my my trigger finger often touches my thumb right before it breaks. This is because my hands are very large and my fingers are long. According to the install video at 7:12, the front face of the trigger should be approx .928in from the front of the trigger guard. I compared that to the 1.12in that I measured with my stock trigger, which would be a significant improvement. Unfortunately after installing this new trigger, I now measure 1.10in, and so don't notice any real improvement in this regard. Basically, the front face of this trigger and the stock curved trigger are at the same forward position when it breaks, and all I learned is that my method for measuring its position differs from how M*Carbo did it. I do like that I now have a flat trigger with a parallel backside, which would theoretically permit me to fasten a ~0.1in spacer to the front face of the trigger with tapped holes added to the trigger face. I'll only do this if I end up getting too desperate with my problem.



Otherwise, the install was smooth and I wisely skipped through most of the video and so didn't needlessly perform what seems like a full disassembly. As soon as I could get the old trigger off, I was able to get the new trigger on (no need to remove sear, etc). I was also able to leave the mag disconnect in place without issue, confirming no fitment with this CA model. Overall fitment seems excellent and I much appreciate the detailed video and well-machined part.

World of difference

Feels solid and a lot better than the stock curved trigger. Zero complaints.



No experience with any gunsmith type work in the past. Purchased a few tools from this site to assist with the process. Took me awhile but I was also replacing the SAS controls with standard Sig slide stop and take down lever.

Shorter, lighter pull and shorter reset. What's not to like? The improved trigger angles and materials made a big difference. My accuracy has improved as well. It's like a different handgun altogether! MCARBO sent a replacement trigger for a problem I never experienced at no charge. How can you beat that?

Worth every penny

My sig p365 was unusable right from the store due to terrible trigger pull which ended up being due to bad machining on sigs part. This trigger coupled with your spring kit saved this gun and now it's everything i wanted in a pistol.

Love the feel of this and the shorter stroke.

Remember that this will STILL be a striker-fired gun. Nothing can change that. (It will not run like a 1911.) There is still take-up, but much shorter, and basically no overtravel. Reset is quicker. Love the feel of this. I like flat triggers generally. I went from the stock, curved trigger to this. Big improvement. I also did the spring kit at the same time. (If I'm going to have the FCG all apart, then come on! I watched the MCARBO install vid twice and the Sig Guy vid twice. Easy peasy.

This trigger is well worth the investment. Take-up and reset are short and positive, providing a precise overall action. I added the spring kit as well, I would recommend it. The overall trigger is much crisper and lighter without being too light. Not having a trigger gage, I would guesstimate about four pounds. The trigger itself is top quality piece,

This trigger has such a short and crisp pull. I absolutely love it. The P365 is already a phenomenal firearm and this trigger takes it to the next level.
