Sig Sauer ROMEO-X Pro 1x24mm Open-Emitter Red Dot Sight (PRO / DPP Footprint)
The Sig Sauer ROMEO-X Pro is a full-size open reflex sight built around a distortion-free aspherical lens and a CNC-machined 7075 aluminum housing. It uses MOTAC motion activation and a side-loading CR1632 battery compartment to keep the optic running without removing it from the slide.
Designed around the SIG PRO / DeltaPoint Pro (DPP) footprint, the ROMEO-X Pro features a low deck height for standard-height iron sight co-witness, 15 illumination settings (including night-vision levels), and a 10mm-rated design.
