Review
Recently purchased and installed in my personal P365XL. I had already polished some internal parts and consistentMy got a 5.5lb. Trigger break. After the Spring kit install I got a consistent 4.5lb. Trigger break. Your results may vary.
Sig made a design change to the newer P365's so I had to watch a different video on slide disassembly than the one on this site. I wouldn't say I'm disappointed but I did expect better results. I ended up with a 8oz (1/2lb) reduction in trigger pull weight and to be honest its barely noticeable. I'll get a better feel for the trigger and see if the spring kit makes a difference when I take the gun to the range.
Excellent video on how to do it. Toughest part was getting the sear spring to seat on the ledge inside the receiver. If you have the correct punch with the right slope, pushing the punch in the hole nearest the spring pushes it right up on the ledge with no problem. Make your own trigger pull gauge, better than anything you can buy. (see pic) Add wrench sockets to get to the ounce. Use food scale to weigh your results.
Shipping was great, price was good, product worked well. The installation video was high quality, but not entirely accurate. The latch system that secures the backplate has been upgraded on newer model guns. Dropping in this spring kit won't fix the gritty feel of the sig trigger. There are a few certain places that need polished to clean the trigger up to a suitable level. This spring kit and a few hours worth of polishing took it from an awful 5.5lbs gritty trigger to a smooth clean 4lb trigger. Well worth the time and money.
This kit improved the feel of the stock trigger significantly. Slightly lighter and seems more crisp now. Highly recommended! The video instruction was great, may need to update to show the new way to remove the new style rear plate.
A very professional company to deal with. Very friendly and helpful. The spring kit was not difficult to install and the result was as I expected.
Flat out Awesome!!!! Prior to the kit upgrade my groups were suffering, after a few mags I was pulling to the left no matter how focused I was on Grip and control. After the upgrade I was speechless.... I followed his YouTube instructions and it was much easier than I expected. I could tell the difference in dry firing after the install and the next day I took it to the range. After about 7 or 8 mags worth of ammo (75+ shots) at 7 yards all of my groups were well under a 3 inch circle most all of them were well within 2 inch. None of the shots were veering to the left. The spring kit upgrade has given me a new found love for my P365xl. Job well done MCarbo
Just what I needed to make the P365 trigger feel 'right'. Great instructions for installation (beware that safety spring will spring into another parallel universe if it gets away from you - reorder as necessary!!). One addition to the P365 instructions: P365XL striker is different and as such removing the rear slide cap has changed. The instructions state that you should pull the striker shroud release forward while prying downward to release the rear cap. On the P365XL the striker shroud has been changed and to remove the rear slide cap you now have to push the striker shroud tab downward and toward the center line of the slide to release the slide cap. BTW, shipment of kit was super quick. . . ordered on Sunday and was in my mailbox on Wednesday using standard USPS. Great job guys on first and second order!!!
I installed the M*CARBO spring kit in my Sig 365 with XL body The kit is easy to install if you follow the great video and will lead to an improvement.
Big improvement, easy to follow video. While disassembled also installed titanium striker. Spring kit comes with 4# striker spring but the titanium striker itself comes with a 3# spring along with updated information on the striker housing redesign. Used the 3# spring and have put about 300 rds without any problem. Noticeable reduction in trigger pull.
Remember that this will STILL be a striker-fired gun. Nothing can change that. (It will not run like a 1911.) There is still take-up, but much cleaner. Love the feel of this. I also installed the MCARBO flat trigger at the same time. Big improvement. (If I'm going to have the FCG all apart, then come on! I watched the MCARBO install vid twice and the Sig Guy vid twice. Easy peasy.) I'm very happy with the package. Worth it.
This product is awesome and does exactly what they said it would and makes the gun 10 times better !!
First time customer and I couldn’t be more pleased. Finished the spring kit in about 35 min. And everything works flawless. Thank you so much for the install video. not sure I could have pulled it off without the help. Keep up the great work guys you got another customer for life.
The installation was pretty easy using the video. For you older guys an Opti-Visor helps tremendously. Always remember that small parts associated with springs can disappear fast. My trigger was already pretty good at just under 5#. It's now 3.5#. I like it...I Like It A lot!
Amazing product and great videos only time will tell to see how long the springs last but I am hoping forever so amazing.
Buy the kit. Get the flat trigger also. Seriously. Do it now. Installation was smooth. The video Chris posted makes it so any level of gun owner can upgrade their weapon the right way the first time.
