Most Helpful Positive Review Fantastic sight.....again!
As a shooter that is in my 50’s the eyes are not what they used to be. This is a game changer for me. Love everything about this sight. Easy sighting in, small and rugged, battery door on top. I bought the 6 moa for my P320 X5 Legion. I don’t mind the big dot. At the relatively short ranges I ...

Most Helpful Negative Review Does not include proper screws to mount with M17
This is supposed to be directly compatible with Sig M17 P320 but the included screws are too big to fit inside the existing holes in the slide. I was excited to get this mounted and try it out but can't even get it installed and can't find the correct screws anywhere. I'll update this review once so...

SIG SAUER Romeo 1 Pro 1x30mm Reflex Red Dot Sight

by Ron C, from SC, United States Written on November 18, 2025
This is my second purchase of this sight which speaks volumes as to how much I like it. Sight picture is excellent, dot is clear and sharp and holds zero without issues and shake awake works well, saving battery life. What's not to like! Optics Planet's great price sealed the deal and shipping was fast as usual. A perfect transaction and a great product!!
Pros:
  • does the job and looks good doing it
Cons:
  • can't think of any
Best Used for:
  • Every day carry and competion
Would recommend: Yes

JUST BUY ONE

by JD, Verified Owner from MA, United States Written on October 14, 2025
Really nice sight for the M-18. Much faster target acquisition and enhanced accuracy. For example, instead of aligning both the rear and the front sight to the target, all you need do with the red dot is place the dot where you intend to shoot. Great brightness controls, easy to adjust the dot, and built from solid materials. The dot easily mounts to the M-18 by taking the slide off, pulling off backplate and extractor assembly, and unscrewing the two sight screws underneath, removing the rear sight and top plate. The dot screws directly into the top of the slide with the screws provided.
Pros:
  • Fast acquisition
  • solid construction, good brightness adjustment, easy to zero
Cons:
  • nada
Best Used for:
  • shooting fast and accurate
Would recommend: Yes

Excellent Optical

by DJP, Verified Owner from TX, United States Written on September 24, 2025
The view is clear and the sturdy but thin frame allows for a great full view. The zero stays solid and the improvements in my accuracy and speed are noticeable. The price point and performance are very good for my needs. I understand there are better sights, but the marginal improvements are not as important for my uses, I am not a competitive shooter.
Pros:
  • clear view
  • Sturdy well built
  • solid zero
Cons:
  • None
Would recommend: Yes

OG of red dots!

by Ted, Verified Owner from AL, United States Written on September 18, 2025
Sig quality made in USA and doesn’t disappoint. Easy, fast ordering process through Optics Planet. Optic is rugged with or without the steel shroud, easy to install & use, easy to zero, holds zero without issues, can change battery without removing the optic. For a non-enclosed emitter I love this optic. Dot is crystal clear even at higher brightness settings. IMO you can’t beat this optic at the price point.
Pros:
  • Price
  • Durability
  • features
  • Made in USA
Cons:
  • OPEN EMITTER
Would recommend: Yes
