Overview

The SIG Romeo1 Pro targets the full-size pistol market with a large viewing window and robust construction. The steel shroud protects the optic from impacts while providing a corrosion-resistant exterior. The wide field of view makes target acquisition fast and intuitive, particularly for shooters transitioning from iron sights.

Designed to work seamlessly with SIG's P320 X-series and PRO slide cuts, the Romeo1 Pro offers integrated aesthetics and reliable function. The MOTAC system provides motion-activated power management, ensuring the optic is always ready while preserving battery life during storage.

Available in 3 MOA (precision) and 6 MOA (speed) dot options, the Romeo1 Pro suits different shooting styles. The large window is particularly beneficial for competition use where speed trumps absolute compactness. For P320 shooters who want a SIG-branded solution with excellent ergonomics, the Romeo1 Pro delivers.
