M*CARBO Brotherhood

Just installed the P365 spring kit

I wasn t expecting much to replace 3 springs but figured heck 25 bucks. Man was i wrong, these 3 springs made a big difference. I was concerned about making my carry pistol too light but it lightens just enough. The biggest change i feel is the smoothness and crispness of the trigger. I m just blown away and stoked to go to the range lol. Hopefully , they ll open back up soon. Have a great weekend everyone

While I had it apart… installing the stricker spring, While the disassembled I Flitzed the mating surface of sear/ stricker surfaces with a dremel tool and treated all internal areas of the slide where stricker resides with Hornady ONE SHOT. SIG says keep that channel dry.
I deburred all control rods ETC. with flitz and dremel.

My routine maintenance cleaning is ONE SHOT followed by canned air a few minutes later.
BE AWARE, IF YOU HAVE A SAS SLIDE THERE IS A DIIFERENT TECHNIQUE TO REMOVING THE BACK PLATE.See this video !!!

Here is trigger with SAS slide and MCARBO springs and polishing ETC.

A 67% trigger pull reduction.

Picked up the kit and am wondering if I should attempt the install along with the Sig flat trigger?

You are going to go deep into the gun to install the springs so may as well install the trigger at the same time.

Yeah, that’s what I was thinking. I better have someone do it.

It’s not too bad to do. I’ve installed triggers in my 365’s.
The parts are small and it is a bit tricky to do but it is something most people can do.
The spring install video addressed the trigger install, so if you’re going to install the springs yourself you can certainly install the trigger.
However, if you’re concerned at all then find someone to do it.

Does it have a over travel adjustment ? The grayguns does https://grayguns.com/product/p365-straight-trigger/

Videos for trigger replacement


Polishing parts. If you have it apart to change springs and trigger WHY NOT make the action as smooth as possible with about 10 minutes of additional effort ?

Thanks, it’s the OEM Sig flat trigger. I do have the v1 Grayguns trigger in my other P365, had a local smith install it and might go that route again. Any Sig Armorers out there from the Tampa area?
