Description
The SIG Sauer ROMEO-RS Compact Red Dot Sight is a lightweight open-reflex pistol red dot sight on the slim RMSc footprint — purpose-built for compact carry pistols. Its 1x24mm window and molded aspheric glass lens give a clean sight picture, and this model runs a selectable circle-dot reticle.
SIG's MOTAC motion-activated illumination keeps it ready, with 8 brightness settings and a side-loading CR1632 tray (up to 20,000 hours). The hybrid steel/polymer housing keeps it light for carry.
How It Compares
Larger pistol? The ROMEO-RS PRO uses the full-size DeltaPoint Pro footprint. Want SIG's premium RMSc optic? The ROMEO-X Compact. It fits the RMSc footprint — confirm your cut in our RMR vs RMSc guide. Browse all pistol dot sights.
Compatibility
RMSc (Shield) footprint — fits RMSc-cut carry pistols (P365 family, Glock 43X/48, Hellcat, Shield Plus and others). Confirm your slide cut before ordering.
