The SIG SAUER ROMEO-X SIG-LOC PRO is an enclosed pistol reflex sight engineered for use with SIG-LOC equipped slides. The SIG-LOC mounting footprint establishes five contact points to minimize shift in zero under recoil and impact while the bottom-mounted design provides a longer focal length to reduce parallax and reticle distortion. The optic features a fully enclosed optical system, MOTAC (Motion Activated Illumination), and a low deck height for standard-height iron sight co-witness.
