Review

The spring kit for the P365 is great! I installed it on my P365 XL. It took my trigger to right around 4.5 lbs. It still has a little mush through the pull, but that’s not the spring kits fault. I immediately ordered another spring kit for my wife’s P364 XL after testing the kit out on mine. I really appreciate they have a great install video to go along with their product. It made the install super easy.

Great spring kit.

Haven’t put a trigger weight gauge on it but changed my trigger from long heavy creepy to much lighter but not too light. I imagine around a 4.5 lb pull now. Plus a striker and seat polish has this as a great trigger now.

Bought a P365 about 6 months ago, and felt the trigger pull was just okay "for a small carry pistol." Also bought a Sig flat trigger at that time but never installed it. Bought the MCARBO trigger kit, followed the great installation and reassembly video by Chris Nelson, and installed the Sig trigger and did a mirror polish of the sear face and the mating firing pin lug while I had it apart. After all this, my trigger pull averages right at a crisp 3 lbs on my Lyman digital scale! Great product, MCARBO.

I'm kinda embarrassed to say that I installed this trigger Spring kit with a hammer, two allen wrenches, a small screwdriver and a piece from a metal hanger.



If I can install this kit with those type of tools because I don't have any real punches, or a gun block, and very little experience working on fire arms, then anyone should be able to install this kit with the right tools.

That said, the trigger is definitely more crisp, but more importantly Lighter, but not to light for EDC. I can't wait to go try it out at the range. I would definitely recommend getting this kit for the p365. P.S. Great install video, best one I've used to date. I feel like I know the ends and out of this pistol now. Thanks again

Noticeable difference in trigger pull on my 365 and 365 XL. If you will watch the installation video, it's a fairly install.

I must have trigger spring kit for a lighter pull and consistent break.

Review

The stock trigger had a heavy, spongey pull and was not forgiving if you did not have trigger/grip discipline. It broke so far back that I could not help, but pull my front sight to the right in order to get it to break.



Installing the M*CARBO trigger spring kit gave me a shorter consistent pull while also reducing the pull weight by about 15% - 20%. The shorter consistent pull allows for greater accuracy and grouping. It is a MUST-HAVE if you carry P365.

Dropped the pull weight from 6 1/2lbs to 4 1/2lbs. Big improvement for the price and instantly a noticeable upgrade. Highly recommend.

Received my spring kit today and I have it installed at a local gun shop here in Meridian, MS. The trigger pull is much better than the stock springs. I still have some trigger roughness, so I will have to install the complete trigger package to get rid of the roughness. I like a smooth pull on the trigger.

I'm really happy with this purchase! This new spring set really cleaned up the pull on the trigger. The pull is now much smoother, and has a clean break, a vast improvement over pretty mushy break mine came with out of the factory. Significant decrease in the pull weight, too!

Man is it a pain to install, but it is worth it. 100% noticeable difference. Feels like trigger pull reduced by half but more importantly got rid of the grittiness in the factory trigger. Highly recommend.

I paired this spring kit along with the short stroke flat trigger. The instructional video was very detailed and easy to follow. In my opinion these upgrades are well worth the money spent.
