The SIG SAUER ROMEO1PRO 1x30mm brings a new level of durability and performance to the miniature open-reflex red dot sight, featuring aircraft-grade aluminum housing that ensures corrosion resistance under the harshest environments and a new upgraded point-source emitter that provides increased brightness in day or night conditions with 12 brightness settings. The molded glass aspheric lens has upgraded high-performance coatings for superior light transmittance and zero distortion giving you fast, responsive target acquisition and accuracy. The sight features SIG’s MOTAC (Motion Activated Illumination System) that activates red dot illumination when motion is detected and deactivates dot illumination when motion ceases—allowing for up to 20,000 hours of runtime per battery.
The ROMEO1PRO features SIG’s TruHold Lockless Zeroing System that utilizes twin adjustment springs and ensures return to zero shot after shot. It delivers dependable waterproof (IPX-7 rated for complete water immersion up to 1 meter) and fogproof performance, and includes a ruggedized protective shroud in the box for extreme durability. The ROMEO1PRO is capable of mounting to any SIG pistol or any other pistol machined to accept the ROMEO2 / PRO reflex sight interface and mounting hole spacing using the included M4 mounting screws. It comes backed by the SIG Sauer Electro-Optics Infinite Guarantee and SIG Sauer Electronic Component Limited 5-Year Warranty.
