The Sig Sauer Romeo-X Compact Pro Enclosed Red Dot, Black (brand part no. SORX1400) is an enclosed-emitter reflex sight built on a Shield RMSc footprint from Sig Sauer, giving it broad slide compatibility on compact and micro-compact pistols. The enclosed housing protects the emitter from debris and impact better than an open-window design, which matters for a carry or duty pistol that sees daily use. Its circle-dot reticle combines a 2 MOA center dot with a larger ring for fast target pickup at speed, and the D.A.R.C./SpectraCoat lens coating keeps the reticle clear in a range of lighting conditions. This listing sits under our Lights & Lasers class in our catalog, but it’s a genuine enclosed-emitter red dot, not a weapon light or laser — written up accordingly.
