P365 flat trigger

by Rugbyfool7, Verified Owner from ID, United States Written on December 26, 2025
This is the upgrade you’ve been looking for if you’ve been looking for something other than the OEM curved trigger. There weren’t any other options that were drop in ready that actually improved trigger feel. With these FCUs you’re limited to just changing out the trigger shoe unfortunately.
Pros:
  • OEM
Cons:
  • None
Would recommend: Yes

Nice Trigger Upgrade, Should be standard

by Lee, Verified Owner from PA, United States Written on May 5, 2025
This is a nice little upgrade.

SIGGUY install on this is excellent.

SIG really should make these standard. Now that I've been messing with the P365 platform for awhile, SIG should be embarrassed for the up charge on some of these "upgrade" features. It has to costs them pennies difference for the standard trigger vs.
the flat model. Same for the "Coyote tan" colored grips and such. But hey it's the American way. LOL.

I updated an older model as a "test", and will update newer model the same. It's like model building for old guys.
Pros:
  • Looks good, hopefully works better
Cons:
  • A little expensive, should be standard
Best Used for:
  • P365
Would recommend: Yes

p365 flat trigger.

by Tony Contrera, Verified Owner from OH, United States Written on April 9, 2025
I have gotten spoiled by flat triggers and other than revolvers I will not purchase a modern pistol that can't be converted.This one through no one other than Sig Sauer was a pain to install ,especially with fat sausage fingers.

Great Trigger Enhancement

by David, Verified Owner from FL, United States Written on March 12, 2025
This replaces the curved stock trigger. The flat face enhances the finger position, providing a shortened smoother pull. Installation is easy if you have basic tools and mechanical ability.
Pros:
  • Smooth & crisp
  • Shortend pull
  • good finger position
Cons:
  • Mechanical ability required for install
Would recommend: Yes

Flat trigger feels and looks better

by Ajit, Verified Owner from TX, United States Written on March 12, 2025
I have a p365 w a curved trigger. Bought a p365 x macro tacops w a flat trigger. Flat trigger shoots better and looks nicer. So i had to order this to swap out the curved trigger for the flat one on my p365. Not easy to install. But doable. Watch video by sig guy on youtube before doing it yourself.
Pros:
  • Feels nice. Shoots better. Looks good.
Cons:
  • Not easy to i stall. But doable.
Best Used for:
  • Upgrade to macro trigger.
Would recommend: Yes

FYI not compliant in states with magazine disconnect !! (CA)

by BV, Verified Owner from NV, United States Written on February 19, 2025
Factory flat replacement trigger.
No tabs/bosses on the trigger to accommodate the magazine disconnect for compliant states.
When disassembling the FCU, be very careful not to slide the safety pin out all the way, the sear spring rests on it for tension and it’s a royal pain to get the sear spring back in place! Some DIY videos show to remove both the safety pin and sear pin. Look for a video that shows just partially pulling out the safety pin. Even if the safety lever drops out that’s no big deal to put back in. This info is intended for us do it yourselfers, if you’re a pistol/gun smith I’m sure this wouldn’t be a problem for you.
Pros:
  • OEM flat trigger
Cons:
  • Not compliant in some states
Would recommend: Yes
