Install video was very helpful. While I was in there, I polished some of the internal components and swapped the springs. Made a difference for sure and worth the price overall.

I used the kit to replace the factory springs of my Sig 365XL. The trigger force went from 6 lb 11 oz to 4 lb 13 oz (Wheeler gauge 10 redaings each). The trigger also feels very good without being unsafely low. Changing the springs is a bit more involve than what I did before on other guns, but the video is a big help. Note that the rear plate removal is slightly different on the new Sig models (at least mine), also I had to remove the safety lever and reinstall it (not difficult). You can find youtube video for both.

Makes a good trigger great.

A little harder than the video shows but ever at 70+ it can be done. Really lightens and smooths the trigger pull. Mine went from 6lbs to 4lbs 6oz.

Making my EDC Sig P365 trigger from great to excellent!

Saw Chris Nelson's top notch, step-by-step, How-To video on YouTube for the MCARBO Sig P365 enhanced trigger kit. The video sold me on the kit. I can already shoot a 1" 3 shot group at 7 yards on rest with the stock trigger. Can't wait to see how much tighter the 3 shot group will be with the lighter, smoother trigger! (I shoot IDPA BUG matches with my P365 too.)

This is my second trigger kit from MCARBO. My first one was for my Grand Power Stribog carbine. Another excellent trigger kit.

Keep up the good work!

Maybe I got a faulty one?

I bought this earlier in the year and got everything changed out. It was fairly easy with the videos provided. However when going to the range the first time I noticed some rounds were not firing through. Examining the round you can see where the pin hits but it’s as if it’s a dummy round. I initially thought it was the cheap ammo but then I went back with better ammo and same issue. This didn’t happen before the swap. I read all the reviews and multiple forums about this and how great it was and the difference it made so I can’t imagine this is an issue with all but I guess the set I have is faulty?

This is a great product at a great value. I am very pleased with the MCARBO spring kit.



Installation was not the easiest, but the MCARBO tutorial video was excellent. Since my pistol has a manual safety and the tutorial video does not, I looked elsewhere for instructions for removing/reinstalling the manual safety, but that turned out to be a fairly easy task.



If you have a 365, you need to get this spring kit!

Much better than stock

I found the install a little challenging but was able to get the fcu back together and the results were worth it. I also ended up replacing the striker with the titanium striker.

Much more comfortable and controllable trigger pull

I'm new to shooting, and the Sig P365 is my first gun ever. I really like the gun overall, but I found the trigger to be a bit too stiff. I also have a Sig Lima365 aiming laser fitted, but it requires a fairly stiff press on the button to light the laser. That, added to a 72-year-old somewhat shaky grip and relatively long fingers have gjven me a pretty funky shooting situation. When I learned about MCarbo's trigger spring kit which promised a lighter pull, I jumped at the opportunity. The installation was quick and easy. I also installed MCarbo's CNC Flat Trigger at the same time, which I also like quite a bit. Though I'm still just starting to practice with the new setup, while dry firing to feel the new trigger pull, I tried pressing the laser light button at the same time to see how that felt. Of course, I'll try it at the range, but I'm finding that by shifting my grip back around a bit, I can use the stronger second bone of my middle finger to hold the light on, while I use the FIRST bone of my trigger finger to pull the lighter trigger. It's also a smoother, shorter throw.

My stock trigger was gritty. I was looking for something to relieve the grit. I saw an ad for the MCARBO trigger spring kit, so I gave it a shot. Man am I glad I did. The trigger on my P365 XL is so much smoother and lighter now. The instructional video was spot on for most of it. The only variation is had to contend with is that the striker housing on mine is the newer style, while the video shows the previous version. I had to watch a separate video to help with that part, but other than that, spot on. I had no issues changing the springs out myself. Much better feel now. Still need to shoot it, but dry firing it, I can tell a huge difference. Thanks MCARBO!

Must have

Mcarbo is great! The offer quality parts at great prices and deliver faster than dominos!

My new sig 365 trigger pull is so much lighter and smother. Mcarbo had a great instructional video that walks you through in great detail with good information. I will buy more from them

Must have upgrade

I own a Sig P365 for concealed carry. I purchased a flat trigger a couple months ago and decided to go with a spring kit as well. The P365 is known for the smooth trigger and the spring kit only made it better. Happy I made the upgrade and happy MCarbo was the company that helped with it.

Must have upgrade for your p365 series trigger.

The trigger pull reduction that this kit provides makes shooting the p365 much more enjoyable. It was relatively easy to install using mcarbo’s videos, however Sig has changed the way the striker is held in the slide so you may need to reference newer takedown videos until mcarbo updates theirs. Can not recommend this product enough.

Easy to install. Striker spring was just a little light for my particular weapon. About a 5 percent of the rounds had light primer strike. Might be just fine for other users.
