Most Helpful Positive Review Decent Sig Optic
This optic is nicely made. The window is slightly taller than the Eps Carry. The glass has a slight blue tint, but the glass is extremely clear. The only issue I had with this optic is that it is only direct mount on a Sig P365 XL if you buy different screws. There are three sets of screws that ...

Most Helpful Negative Review Tried twice
Originally purchased this red dot sight and mounted it on the pistol. Once mounted, I noticed what many have noticed. The rear glass had glue overspill to the point that it looked like a protective film. I decided to return the dot to avoid the distraction it would have caused. I ordered a second d...

Sig on Sig

by Crkshot, Verified Owner from CA, United States Written on February 3, 2026
I love my new RomeoxCompact! Big help for old eyes that can see either the front sight or the rear sight, but not both! I love the abilty of fast target acquisition and the related accuracy associated with the combination of my new Sig 365xmacro and the Sig RomeoxCompact sight. I purchased the enclosed version, which is more money, but it is a
more reliable system in my opinion. As a former military officer, I prefer to use similar products to the military contracts, if I can find them. You will not be disappointed with this product!!

Romeo-X compact enclosed

by JT, Verified Owner from CA, United States Written on January 30, 2026
Nice red dot, the housing chips and finish comes off very easy however, not a cheap item by any means, I would expect it to hold up better.

Huge improvement over SIG Romeo 1 Pro

by Tampa Mark, Verified Owner from FL, United States Written on January 3, 2026
- This SIG Romeo X Compact Enclosed red dot sight is every bit as high quality as the price implies. Precision craftsmanship of the highest order.
- I installed this SIG red dot on a CZ P09 F Nocturne SR, specifically so I could use it suppressed. I was not disappointed.
- I already have experience with a SIG Romeo 1 Pro with a 3 MOA dot. What I have noticed is sometimes I can't locate the dot (upon presentation) and I don't know if it's up, down, left or right.
- Because of this, I ordered the "Red Circle Dot" model. This was a good choice, since now I can locate the dot immediately upon presentation.

It’s an overpriced, underperforming Holosun EPS

by Skooche, Verified Owner from OR, United States Written on December 21, 2025
Mounted this dot as a replacement for my Holosun eps carry on my 365 x macro. I haven’t done any durability testing as I’m not made of money or willing to try and break my carry setup. However the parallax between the two I find that the Holosun is far more true, and has a noticeably better ability to keep the dot on target regardless of head position behind the dot over the sig. it may just be my eyes but the sig is also not as clear of a dot, the Holosun is a perfectly round red dot to me, the sig has more of a bloom to it, especially on higher brightness settings. Also the glass on the sig is like looking through old school blue and red 3D glasses, they’re heavily tinted especially compared to the Holosun. I would not recommend the higher price tag of this over Holosun sadly. I really wanted to like it, but I immediately noticed these differences without even having to hold them side by side, and it becomes more clear once you do.
Pros:
  • None
Cons:
  • Expensive
  • blurry dot
  • Bad parallax
  • Heavy tinted glass
Would recommend: No

on paper, this is the best optic available

by mike, Verified Owner from TX, United States Written on November 6, 2025
If you look at the specifications, you’ll see everything was done right. Multiple reticles to choose from. Enclosed. Low deck height that allows you to cowitness with iron sights. However the assembly is definitely where this falls short. The optic came with glue smeared all over the glass and pouring over onto the aluminum housing. The battery cover scratches if you breathe on it wrong. Okay that last part is exaggerating a bit but you get the point. For half of a thousand dollars I expect more pride taken in the making of this optic. All cosmetic? Hopefully but if this is how it slapped together, how am I expected to trust the internals? No dlc finish, and glue that looks like it was put on by a child. USA made? No. USA assembled with foreign parts. If that’s the case I’d rather get suppressor height sights and pick up a holosun. Now in no way do I think this is on optics planet. I’ll continue to order my gear from them every time. But sig, you’re over charging and not delivering.
Pros:
  • Low deck height
  • Multiple reticle
Cons:
  • Finish
  • Assembled wrong
Would recommend: No

Romeo X 3MOA .

by Dogstar, from FL, United States Written on June 25, 2025
I bought this for an Sig p322 . Easy installation , had no issues with the screws . Well made with a little larger window than the Holosun red dots . The built in rear sight is a great idea . Side mounted battery is good feature too . I gave the review 5 stars because I’m only going to use this for a range gun . I would not use this or any micro red dot for a self defense weapon . The window is just too small . Dot acquisition in a stressful situation would be difficult or at least more time consuming . Iron sights would be way quicker . Some people would argue that you could train for that but I think the majority of people would prefer irons on their sub compact carry gun . Keep it simple .
Pros:
  • None
Cons:
  • Not for self defense
Would recommend: Yes
