The next generation of SIG SAUER'S competition-ready pistol reflex sight is here. The ROMEO3PRO is the embodiment of a lifetime of repetition and experience in the competitive environment, refined over tens of thousands of rounds to deliver the most dominant optic to date. Transitioning to the standardized SIG PRO footprint, the ROMEO3PRO will mount directly to your favorite SIG SAUER full-sized optics-ready pistol while maintaining an ultra-low deck height to optimize height over bore axis. SIG's industry-leading aspherical glass lens system provides a generous sight window with unrivaled clarity to expedite target acquisition and eliminate distortion.
