The SIG Sauer ROMEO-X Pro Green Dot Sight is a premium open-reflex pistol optic on the DeltaPoint Pro footprint. This model runs a bold 6 MOA green dot — the quickest reticle to find under stress and ideal for close-range defensive shooting.
A distortion-free aspherical lens, MOTAC + MAGNETAC activation, 15 brightness settings (3 night-vision), a top-loading CR2032 tray and IPX8 sealing make it a rugged everyday choice.
