Review

I didn’t do official pull weight tests on my stock spring and the MCarbo p365 spring kit, but the entire trigger pull was noticeably light, including the break. I was having some accuracy issues with the stock spring (yanking my shots low left) and after shooting at the range with this spring installed, I was hitting center all day. Excellent improvement for the p365 for people who don’t shoot accurately with heavier trigger weights. I couldn’t find anyone else making a spring kit for the p365.

Awesome!!

the instruction video, could not have been better. for a process that requires breaking down the entire receiver, that is usually scary if your not a gunsmith, but their instructional video was fantastic. the trigger pull is smooth and noticeably less tension, and just as advertised, I tested it, and it was 4.9 lb after installing the 3 spring kit.

Back plate update needed in Utube

Took me longer to deal with the back plate than anything , trigger feels good, looking forward to going to the range

Be aware of ammo with harder primers

Had the trigger and spring kit installed at my local gun shop. Have to say that there is a noticeable upgrade from stock on my P365 with Radian Ramjet/Afterburner with the DPM light recoil system. Be aware though that you may experience light primer strikes and failure to fire (FTF) if using ammo with harder primers. This is not due to the MCarbo trigger, but rather the spring kit. Ran flawlessly with Federal Ammo but have had many many FTF using S&B and Maxxtech 115 gr 9mm ammo. Do some forum searches and you will see I'm not alone. Stick with better ammo and you'll love it, or maybe plan to use the stock 5lb striker spring. I'm still using the 4 lb. spring that came with the kit and am searching for other ammo to try. I was totally unaware of this issue. Not knocking MCarbo per se, but more so hoping to help others that are unaware.

I installed this puppy on my p365 XL it was a breeze especially when you watch there install video on You Tube. The spring kit Is awesome got rid of my over travel after I hit the wall, now it cleanly breaks every time highly recommend. If you are thinking about getting it just do it its worth the money.

Best $20 I have spent in a long time!

Very impressed with the quality of the product as well as the professionalism in the instruction video. The results are amazing! I took me about 30 minutes and it was well worth the time.

I replaced the springs when I did the flat trigger upgrade but there was only one trigger at my local gun shop so I did the springs on both guns. The factory trigger actually became halfway decent with this kit. So if you only have 20 bucks you can't go wrong purchasing this spring kit. But I do have to recommend you get the Flat Trigger as well but that's for another review.

Best 20 bucks,Ive spent!

Wow what an improvement on the stock P365 trigger. This upgrade took the pistol to a whole other level and it's not that hard to install on your own. Best $20 upgrade I've seen honestly on any gun. Don't think just buy it you won't regret it.

Best thing since sliced bread!

M-carbo trigger spring kits:



I have installed two of these one in my P365 & one in my P365X.. The kits arrived on time and I immediately got an email from Chris Nelson President @ Mcarbo making sure all my goodies had arrived.. The feedback from others is nothing less than Glowing.. The video that MCarbo has done is extremely well done and is definitely a great resource to those who are new to the P365 in order to complete the install job. The video is produced with extreme efficiency, and attention to detail with very clear & concise instructions & camera angles, some may even say it’s a bit long & drawn out. But when dealing with very small parts such as these, one cannot be overly communicative in the process. O do recommend that the video be updated to reflect the new Slide Back plate style of the Gen 3 guns.. and also, the deletion of the small spring in the Striker should be mentioned, as well as the sear changes.. the new style Sear has an indexing hole 🕳 to receive the long end of the new Sear spring.. and the install is made so much easier by this implementation…. I cannot recommend this company’s staff & its products enough.

I'm so impressed with the outcome of the trigger kit!

I purchased a Sig Flat Trigger & installed this kit & I couldn't be happier! Smooth pull & re-set, around 4.5 lbs. and I shoot better with the P365 than I do with my P320 Pro! I can't wait for a kit for that gem! Thank you MCarbo for a great quality product and a A+ installation video! You have a new customer who works in the firearms industry and I refer folks to your products daily!

Thank you again for being there for your U.S. brethren (& Sisters)!

Keep on crankin' out the great product!

best upgrade for $20

Installed on my P365. hardest part was getting the black clamps on the firing pin spring, Guess it would have been easier if I had the block used in the video. after install can tell lighter trigger pull. didn't measure before or after. also while installing put in Sigs flat trigger. Both combined are excellent. only 100 rounds but no problems. Primer strikes look same, never had any primer drag. Plan on shooting another 500 rounds soon then update review.
