MCarbo P365 spring kit - my Frankenstein-Specter
I picked up a Specter XL (non-comp) slide assembly from the classifieds and ordered a Sig Custom Works FCU from Brownells along with a Wilson Combat XL grip a PSP gold nitride trigger, a Tactical Dev pic rail & a couple MagGuts magazine upgrade kits.
I have the MCarbo spring kit, anyone installed it & what was / is your experience ?

I can't comment on the Mcarbo parts but that is a really nice looking pistol you have there.

Out of curiosity, how is the trigger on your Custom Works FCU out of the box? I wouldn't think you would need to install the spring kit if it feels good but if it's one with a squishy trigger people complain about, then I would be interested in knowing if the spring kit cured it.

I put the MCarbo spring kit in my regular P365 and it was great for about 1000 rds. Then it started getting light primer strikes and I reinstalled the stock springs. Lots of other reports on this. You're good for about 1000 rds. But then the kit is cheap and it's just as much work to install a new MCarbo kit as to reinstall the stock springs.

I think the main culprit for the light primer strikes was/is the reduced power striker spring.

I used Armory Craft Reduced Weight Striker Block Spring (-25%) and the Reduced Weight Sear Spring (-25%)

I didn’t buy the reduced power striker spring.

Cleaned up the trigger nicely.

I may wind up going the Armory Craft route then.
Is there any part of the Mcarbo kits worth installing? I have two kits & four P365s.

I particluarly like the Wilson Combat grip module. I have it on two of my P320s. Really, like it.

I installed the MCarbo kit sans the striker spring. I didn't want to sacrifice reliable ignition for the small benefit of a lighter striker spring. This set up improved the trigger sufficiently for my needs. I think I'd have the same hesitation with the Army Craft kit.

I put M-Carbo spring kits in a 365 and 365X. I found them easy enough to install and greatly improved the trigger pull on both.

Edit to add no reliability issues with either gun
