Excellent Upgrade...
I have Apex flat triggers in all my P320s (5) so was very happy to find MCARBO's Flat Trigger for the P365 XL! Works like a dream and reduces take up in the trigger and reset is much better than the SIG Flat Trigger! Worth every Penny. BDU
Love this trigger
So much better than the stock trigger barely any take-up and a nice crisp break also installed the spring kit and you can tell it took off a few pounds
Very Happy
Installed this trigger and the spring kit on my 365xl with my new Icarus frame and it looks and feels amazing. Excellent instructional video on how to install and more importantly, put your entire gun back together! Great work on this product and the spring kit as well as the logistics from order confirmation through to delivery!
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.
I LOVE THIS TRIGGER!
I bought one of the first run of this trigger and absolutely fell in love, especially after already having the spring kit installed.
Watching the instruction video twice really helped, especially after being a GLOCK armorer for so many years(Sig handgun lock work is much more complicated). The only real trouble I had was with a pin at the trigger. I had to remove it partially to get the trigger in, but it was pretty easy once I realized how it all worked.
Between the trigger and spring kit, I'm getting a consistent pull of 3.5lbs on my Wheeler digital trigger weight gauge, which is right where I like my triggers to be set.
I plan on upgrading to the M*Carbo Titanium P365 striker very soon!
I received the V2 trigger from M*Carbo and it went in quite a bit easier than the V1. M*Carbo just dropped one in the mail and didn't ask for the old one back.
Talk about customer service! That's how it's supposed to be done!! I'm still at 3.5lbs on the trigger weight, but with slightly improved take-up(it was already amazing with the V1) and a slightly cleaner break(also very good on the V1 trigger).
Thanks M*Carbo for the killer service, incredible selection and innovation! I'm be a repeat client as long as you're in business.

Great Trigger
This trigger along with the spring kit improved my accuracy, and feels great on the pull. So far I have shot about 150 rounds in a variety of ammo and have had no reliability issues at this point. Also the quality is fantastic. I would definitely consider this an upgrade from the factory sig curved trigger.
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.
May not be for the P365 in 380
Spent hours trying to make this work. Took it apart and reassembled it multiple times. Could not get the slide back on. Realized the safety lever was being forced up slightly with the new trigger installed. If I took the trigger pin out the trigger bar would move forward enough to let the safety lever down enough to let me put the slide on. Tried installing it on a friends 365 9mm and it went in great and functioned properly. The instruction video was very helpful, but the customer service not so much.

Anyone able to confirm this trigger and sear spring group will work in the new version P365X with manual safety?
The FCU for the 365 models are the same, the only difference is slide length and grip size of the pistols. We also have had good feed back from our 365x customers.
Is there a date of these triggers being available? Or is is it best/quickest to order and will ship when ready?
We recommend placing your order and we will ship it out as soon as possible! We are currently non-stop running these triggers in our CNC machines and are sending them out in batches to our Vendor for the surface finishing process. All backorders are being filled oldest to newest, so placing your order will keep your spot in line :) We are working as hard as we can to try to catch back up!!
If I order one on 4-13-2022 when would it ship with the back order?
we are sending out batches of machined triggers to our Second Process vendor for surface finishing on a consistent basis and will fill all backorders in the order of when they were placed! The average lead time between batches is around 3-4 weeks, depending on our vendor's lead times and shipping.
How's the trigger reach on this versus the standard curved trigger? I tried the factory flat trigger and went back to the curved because it was easier for me to reach.

The resting position of our Flat Trigger sits further back than both of the OEM triggers, with the "short-stroke" shortened pre-travel instilled in its design. This will allow you more space for your finger between the trigger and the guard and will be a much more comfortable reach. Chris does cover this in our recently uploaded video as well!
