Did this or something different on my girls P365

by Ryan S, from OK, United States Written on May 30, 2026
It’s all factory Sig parts so they work perfect. I also did the safety. Everything came out great and it looks super cool with just these little touches.

Shiny and functional, if only they sold the trigger by itself

by Danger, Verified Owner from IN, United States Written on April 18, 2025
These parts match the same finish found on the Rainbow P365x and P365 380 that Sig currently offers. Those firearms however do not include the rainbow finish trigger found in this kit. Sig does not sell the rainbow trigger by itself (despite selling other P365 triggers as standalone items) so if you want that trigger this kit is your only option. 

At some point Sig redesigned the takedown lever to hold the 6 Oclock position and this kit's takedown lever is of that newer design. My old P365 was purchased in the first year or two of introduction and is of the original design that just slaps back into the 3 Oclock position while you're messing with it. I'm not certain when that new design happened but it is a thankful addition that this kit provides. 

The kit comes with no instructions so if youre going to handle the install yourself i recommend Sig Guy on YouTube for his video that gets into the details. As it is, if you purchased the Rainbow P365 it's nice to have this whole kit to have the trigger that matches but also includes the Rainbow mag release if you wanted to have a matching mag release on a different sized grip module to swap the FCU into.
Pros:
  • Very attractive finish
  • Enhanced functionality for older P365's
Cons:
  • Trigger not available as a standalone item
  • Expensive cost of entry for just the trigger
Best Used for:
  • Custom build/personalization
  • Completes the "wife's" gun
