The Sig Sauer Romeo-X Enclosed Compact 3 MOA Red Dot, Black (brand part no. SORX1430) is a fully enclosed, sealed pistol red dot with a 3 MOA red dot reticle on the Shield RMSc footprint, built to mount directly on the P365 and other compact and micro-compact pistols. Sig machines the housing from 7075 aluminum around an argon-purged optical system, with an aspherical glass lens and a high-efficiency point-source emitter for a distortion-free sight picture. The battery loads from the side, so changing it never disturbs your zero, and MOTAC motion activation stretches a single CR1632 to a rated 20,000 hours. The deck height is low enough for absolute co-witness with standard-height iron sights. For a carry pistol that needs a durable, enclosed dot without a slide that gets taller, it is Sig’s answer.
