Sig Sauer Electro-Optics Romeo-X Sig-Loc Pro 1x24mm 3 MOA Green Dot Reflex Sight - Black

The Sig Sauer Electro-Optics Romeo-X Sig-Loc Pro is a duty-grade enclosed-emitter reflex sight purpose-built around Sig Sauer's proprietary mounting footprint. The compact 1.90" housing carries a 3 MOA green dot reticle through a 24mm objective lens, finished in matte black to blend with factory slide cuts.

Designed to drop directly onto optics-ready Sig P320, M17, M18, and P22X-series pistols without an adapter plate, the Romeo-X is built around the Sig-Loc Pro footprint. A fully sealed 7075 aluminum housing protects the LED from debris, moisture, and pocket lint in the harshest carry environments, while the aspherical lens delivers a distortion-free sight picture with no blue tint.

Sig Sauer's MOTAC (Motion Activated Illumination) wakes the reticle on movement and shuts it down during periods of inactivity to preserve battery life. A side-loading CR1632 battery tray allows swaps without dismounting the optic from the slide, and the rugged enclosed-emitter design is built for everyday carry, duty, and competition use.
