Sig Sauer’s ROMEOZero-Pro and ROMEOZero-R series are full-sized optics that are designed for applications on compact to full-sized handguns. Compatible with any handgun featuring the ROMEO2/Pro mounting footprint, these optics come equipped with a sizable 30mm aspherical lens for a wide field of view and enhanced situational awareness. The lens is constructed from scratch-resistant glass with full multi-coatings, ensuring a sight picture with unmatched clarity and free of distortion. The ROMEOZero’s housing is composed of a proprietary carbon-infused polymer. The polymer housing is ultra-lightweight to guarantee reliable cycling when mounted on compact pistols. The polymer design also provides superior durability when compared to pistol optics made from aluminum, allowing the ROMEOZero to easily withstand drops, impacts, and sustained recoil. Other features of the ROMEOZero include Sig’s innovative T.A.P. (Touch Activated Programming) Technology, which allows the user to change the reticle’s brightness by simply tapping the optic. In addition, the ROMEOZero is outfitted with anti-reflection grooves, and an backup rear sight notch with grade-A Swiss SuperLuminova pigment for optimal visibility in low-light situations.
