Most Helpful Positive Review Very Nice Build Quality
I just received my Romeo-X this afternoon and already mounted it to my P365-XL. Fit and finish are fantastic and it looks good too. Can’t wait to get it out to the ranch this weekend. I’ll try to report back after I get to shoot it.
Most Helpful Negative Review it's ok. still not as good as Trijicon.
Glass is just ok for what it is. Sig made good weapons but for optics (nah). They are still using Chinese electronics components and assembled in States and advertised as Assembled in US to jack the price up. Stick with Trijicon.

Very happy

by Caleb Steel, Verified Owner from MN, United States Written on January 23, 2026
I bought the Sig Romeo X compact for my girlfriend’s Sig P365 .380 Rose. Not only did it tighten up her pattern but it also sped up how fast she got her sights back on target to pull the trigger again. I like it, more importantly, she likes it. I just feel sorry for the sob who breaks into our house and is at the receiving end of that. Hope this helps

Great for P365 with old style optics cut

by MicStage, Verified Owner from NC, United States Written on January 22, 2026
This sight works well with both my P365 and P365xl with old style optics cut. You lose the rear sight on the older P365 when you remove the optics plate. This sight has a nice co witnessed fiber optic rear sight. So no worries if the red dot dies. Buttons are a little small though.
Pros:
  • co witness fiber optic rear sight
Cons:
  • small buttons
Would recommend: Yes

Romeo X Compact

by JBH, Verified Owner from AR, United States Written on December 9, 2025
So far, this seems like a great red dot. I went with the circle dot. So far, so good!
I see people claim that dust could become an issue with impeding the red dot, but I’ve never experienced such an issue with any open red dot sight I’ve ever owned. My Trijicon RMR’s have worked flawlessly as well. Enclosed is not a must, but is fine if you should choose it.
Pros:
  • Works as designed. Flawless function.
Cons:
  • None
Best Used for:
  • optic ready compact pistol

Defective Reticle

by Marspogo, Verified Owner from WA, United States Written on June 6, 2025
Brand new out of the box sight would not change reticle (press down button and hold > 1 sec). Tried replacing battery, turned off and on, no success. Reached out to Sig customer service in the hope they might shed some light on issue, no reply! So, along with the p320, appears Sig has QC issues elsewhere.
