SIG SAUER ROMEO-RS Compact Clear Circle-Dot Sight

Description

SIG SAUER ROMEO-RS Compact Clear Circle-Dot Sight

The SIG SAUER ROMEO-RS Compact Clear is a lightweight 1x reflex sight sized for slim, optic-ready pistols that use the compact Shield RMSc footprint. This SOR02101 configuration combines a distinctive clear housing with a red circle-dot reticle made up of a precise 2 MOA center dot and a highly visible 32 MOA circle. The reticle gives the user a fine central aiming reference while the larger ring supports quick visual acquisition.

The ROMEO-RS uses an open-emitter design with a premium aspherical glass lens. SIG SAUER’s SpectraCoat treatment is applied to support light transmission and reduce unwanted reflections. Unlimited eye relief and true 1x magnification allow the sight to be used with both eyes open without requiring a fixed viewing distance.

Compact Construction

A skeletonized steel chassis is molded into the polymer housing, reinforcing the optic while keeping its profile and weight appropriate for compact pistols. The clear exterior gives this version a distinctive appearance while retaining the same compact architecture as the standard ROMEO-RS Compact family.

The sight measures approximately 1.61 inches long, 1.12 inches wide, and 1.10 inches high. Its Shield RMSc-pattern footprint is commonly used on slimline and micro-compact optic-ready slides. Footprint standards do not guarantee direct compatibility with every firearm, however, so confirm the slide cut, screw dimensions, and any required mounting plate with the firearm manufacturer before installation.

Illumination and Battery System

The red LED reticle provides eight brightness settings for different ambient-light conditions. Large side controls make adjustments accessible without covering the lens. SIG SAUER’s MOTAC motion-activated illumination system powers the reticle down after inactivity and restores the previous setting when movement is detected, helping conserve battery life while keeping the sight ready for normal use.

A side-loading tray holds one CR1632 battery, allowing battery replacement without removing the optic from the slide. SIG SAUER rates the sight for up to 20,000 hours of operation at medium brightness with the dot-only setting. Actual runtime varies with reticle selection, brightness level, battery quality, temperature, storage conditions, and frequency of use.

Adjustment Range

The ROMEO-RS Compact provides 70 MOA of total elevation travel and 70 MOA of total windage travel. That adjustment range supports zeroing across compatible compact-pistol applications. Installation and zeroing should follow the SIG SAUER operator’s instructions and the firearm manufacturer’s mounting guidance. Use only the specified screws and published torque values, and confirm function and zero after installation.
