I was hoping for a little better trigger function without making it too light. This kit was perfect and I'm very pleased with the results. The video was spot on and it probably took me a little less time then the length of it for all of the work (including a flat trigger install). I watched it once, and then just kept it up while doing the work for reference. Highly recommend the kit to anyone considering it.

Great kit!

Installed this spring kit on my 365xl and went from a 6.5 lb to 4.0 lb trigger pull. Took out the grittiness and performed flawlessly on test shots after installation. I do have to mention that I also have a Kahr CM9 as my primary CCW with their trigger spring kit installed that was originally a gift from a family member that was a great upgrade which prompted me to buy this for my Sig. Fast shipping,great service, and a small veteran owned business makes me a repeat customer!

Great kit, easy install

Quick shipping, arrived on time. Relatively easy install using the installation videos. I'm not a gunsmilth and don't have a lot of experience disassembling and working on guns, but the video enabled me to get it done. Very happy with the results.

Great kit, great installation guide

Great value and functionality on this kit from MCarbo! Huge difference in feel and a nice crisp reset. Their installation videos are thorough and informative, made the task a breeze. The only thing I need now is for MCarbo to make a flat trigger for the P365 with adjustment to clean up some of the pre-travel and take up.

This does a lot to change the feel of your trigger. Goes from notchy to very smooth. I polished the sear which also helps. The stock trigger pull measured consistently just above 5lbs. After the install, it measures just above 4lbs. but it's very smooth! I also have the Armory Craft flat trigger which gives it the feel of even less poundage. Great product!

Great parts and service

My order was in the mail the same day I ordered it even during this COVID shutdown. The kit installed as advertised and works great! Significant reduction in pull weight. No downsides to this kit.

Great Performance Upgrade!

Found MCARBO by accident on YouTube and ordered the spring kit right away. Great communication and fast shipping. The video was not only instructional but educational, giving me a better understanding of FCU and how it operates. The kit dropped my pull weight from 6# to 4# with a smooth feel throughout the pull.

Made in the USA by "Interesting and Dangerous Americans" with a 100% Lifetime Guarantee what more can you ask for, so go ahead pull the trigger (no pun intended) on this great product you will not be disappointed!

Great price for great performance

This is a $20 trigger spring kit, not a new trigger. It definitely reduces the trigger pull weight. It's a shame the pre-travel and 'squishy' trigger mask the improvement IMO. More on trigger feel at the bottom.



Installation was straightforward*, and MCARBO's installation video is a great reference, if even for just the armorer's knowledge it covers. If you are not mechanically inclined, do yourself a favor and watch it first. Make sure you have all the tools needed. Then watch it again, before doing anything.



As for usage, safety functions checks passed and felt normal. Firing, I ran 15rd magazines, with 5-shot rapid-fire strings, and controlled pairs, and it worked as expected.



I would definitely recommend this to anyone using the P365/P365XL/P365SAS platforms.



If you understand striker fire triggers are subject to tolerance stacking, which is what causes their characteristically 'squishy' feel. This spring kit will not eliminate the pre-travel or feel.

Great price for improving trigger

The kit is very basic and simple. One of the gunsmithing blocks should also be purchased with the kit. Saves you time and grief. Just pay close attention to the installation video.

Great Produce!!!

First I would like to say is what a great company to work with and the shipping was spot on. The spring kit video was the finest instructional video I have ever seen first class, I followed the video and the installation was fairly easy for a guy who doesn’t work on guns. The results were great nice trigger action and a crisp reset unfortunately I am unable to measure the trigger weight but it did definitely reduced it. Very satisfied!!

Fast shipping. Had the Mcarbo install video on my tablet and it all went smoothly. Put in the Sig flat trigger at the same time. Knocked 2 pounds off the pull.
