Sig Sauer ROMEO-X Pro 1x24mm Open Reflex Red Dot (PRO / DPP Footprint)
The Sig Sauer ROMEO-X Pro is a full-size open-emitter pistol reflex sight built around a CNC-machined 7075 aluminum housing with a distortion-free aspherical lens. It uses a side-mounted CR1632 battery compartment to allow battery changes without removing the optic.
Designed for PRO footprint slides (DeltaPoint Pro / DPP pattern), the ROMEO-X Pro features MOTAC (motion-activated illumination), 15 brightness settings (12 daytime plus 3 night-vision), and up to 20,000 hours of runtime at a medium setting (dot-only). Rated for 10mm and sealed to an IPX7 water-resistance standard.
