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 Sauer Romeo-X Compact

by Daniel R., Verified Owner from LA, United States Written on November 7, 2025
After installing the Romeo-X onto my Sig Sauer and dialing it in, I haven't experienced any shift and hits right on target.

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

Perfect design

by Bean, Verified Owner from SC, United States Written on February 27, 2025
This red dot is the perfect design for the p365. No surprise there. If you're looking for an optic for a compact don't miss this one. Super clear glass and a clean dot. The circle dot model can view bothe the circle dot or just the dot. Definitely the way to go.
Pros:
  • Design
Cons:
  • none so far
Best Used for:
  • Personal & home defence
Would recommend: Yes

Dot failure

by Disappointed, Verified Owner from CO, United States Written on February 17, 2025
Sig needs to get it's act together on QC. Mounted to specs all looked good. Took it out of the safe a few days later.No dot thought might be battery. But noticed red light coming from some where dot was shining on top of the inner shroud.
Pros:
  • None
Cons:
  • Didn't work
Would recommend: No

Defective; also missing parts. Very disappointed.

by LivingUpNorth, Verified Owner from ID, United States Written on February 15, 2025
I was super excited to get a fully enclosed optic that fit the RMSc footprint on my micro nine, but unfortunately, my example was a bad one. The unit would randomly power off when adjusting reticle brightness, even with a brand new battery. There was an odd, blurry, blue color around the outer half of the entire window (but not on the reticle itself), so this was not a notch filter you might find on typical optics. And then, there was the fact that the glass itself was visibly distorted, leaving your circle-dot more of an oval-dot.

The icing on the cake was the fact that it didn’t even come with mounting screws, wrenches, or a battery. When I contacted Sig (twice) they only sent the wrenches, which I didn’t really need, to be honest. And still no mounting screws! Luckily, Optics Planet made the return easy, which I appreciate. Great service by OP, but a disappointing product from Sig.
Pros:
  • size/form factor
Cons:
  • Quality Control
  • Packaging
  • manufacturers response
