Sig Sauer Electro-Optics SORX1080 Romeo-X Pro Black 1x24mm 3MOA Green Dot Reticle RX Footprint Mount
$469.99
The Sig Sauer Romeo-X Pro is a purpose-built reflex sight engineered for optics-ready pistols that demand durability and speed. Built on the RX footprint, this 1x24mm green dot sight delivers the low-profile, co-witness-friendly design that modern pistol shooters need—whether you're running drills at the range, competing, or carrying a modern duty gun. Sig's military heritage shows in every detail: the CNC-machined 7075 aluminum housing, the patent-pending beryllium copper flexure arm, and the aspherical lens all combine to create a sight that's tough enough for hard use and clear enough for precision.
The 3MOA green dot reticle cuts through clutter and finds targets fast. Motion-activated illumination (MOTAC) kicks the emitter on when you move and off when you don't, stretching battery life to a remarkable 20,000 hours on a single CR1632 cell. The side-load battery compartment keeps you shooting without breaking your grip or removing the optic, and the ultra-low deck height lets you co-witness with standard-height iron sights—a real advantage if your backup irons ever need to take over. Fifteen illumination settings, including three dedicated night vision modes, give you flexibility in any light.
Everything is designed, tested, and assembled in the USA. The package includes the mounting hardware you need (three sets of M-series screws to fit most platforms), a T10 and T6 Torx wrench for tool-free adjustments, and a fresh battery ready to go. The Romeo-X Pro represents what you get when a company takes decades of military optics experience and distills it into a sight built specifically for the pistol platform you're already running.
