Description
SIG Sauer ROMEO-RS Compact Green Dot Sight pairs the do-everything 3 MOA size with a green emitter, on the smaller RS body built for carry slides. Green is the easier colour for some eyes to pick up in bright light; beyond that it behaves exactly like the red 3 MOA, down to the CR1632 tray and its security screw.

Help & guidance
Product FAQs
Is a green dot actually better than red on the ROMEO-RS Compact?
Green can be easier to see in daylight, and some shooters simply find it stands out more. Otherwise this ROMEO-RS Compact is identical to the red 3 MOA version.
Why choose the 3 MOA size on the ROMEO-RS Compact?
The 3 MOA dot is the size that asks the fewest compromises, quick enough close in and tight enough to keep a target visible further out. It is the do-everything option in the ROMEO-RS Compact range.
Will the ROMEO-RS Compact fit my pistol?
The ROMEO-RS Compact fits common compact optic cuts, so check your slide against a footprints guide before ordering. It is built on the smaller RS body designed for carry slides.
What battery does the SIG Sauer ROMEO-RS Compact take?
It runs on a single CR1632 in a side-loading tray held by a security screw. Runtime is around 20,000 hours, with MOTAC waking the dot on movement.
What reticle does the SOR02180 have?
The SOR02180 has a 3 MOA green dot. It is a compact open reflex sight at 1x, parallax-free with unlimited eye relief.
How many brightness settings does the ROMEO-RS Compact have?
The ROMEO-RS Compact has 8 brightness settings. It also uses MOTAC motion activation, which shuts the dot down when the pistol is still and wakes it on movement.
What is MOTAC on the ROMEO-RS Compact?
MOTAC is the motion activation system that wakes the dot when the sight moves. It is a key reason the ROMEO-RS Compact reaches around 20,000 hours from one CR1632.
What is the ROMEO-RS Compact made from?
The ROMEO-RS Compact uses a skeletonised steel chassis moulded into a polymer housing. That construction keeps the small RS body suited to carry slides.
Do I need to remove the ROMEO-RS Compact to change the battery?
No, the CR1632 sits in a side-loading tray, so it can be reached from the side. The tray is secured by a screw.
What is in the box with the ROMEO-RS Compact green dot?
The box contains the SIG Sauer ROMEO-RS Compact green dot sight, mounting hardware and a CR1632 battery. That is the full listed contents for the SOR02180.
What other versions of the ROMEO-RS are available?
Alongside this 3 MOA green model there is a 3 MOA red ROMEO-RS Compact, a 6 MOA green ROMEO-RS Compact, and the ROMEO-RS PRO Green for full-size pistols. The SOR02180 is the 3 MOA green Compact.
How long is UK delivery on the ROMEO-RS Compact?
Estimated UK delivery is 10 business days. It ships as genuine UK stock, so there are no import fees to pay on arrival, and checkout is secured by Shopify.
