The Sig Sauer Romeo-X Pro 3 MOA Compact Red Dot, Black (brand part no. SORX1030) is a slide-mount reflex sight built around a Deltapoint Pro footprint, giving it a wide range of factory-milled slide compatibility. Sig Sauer finishes the housing with D.A.R.C. and SpectraCoat lens treatments to cut glare and improve dot visibility across lighting conditions. The 3 MOA dot is a versatile choice for both fast target transitions and more precise shots, making it a solid pick for a defensive or competition handgun. Note: this listing is filed under our Lights & Lasers class in our catalog, but it’s a genuine red dot optic, not a weapon light or laser — we’ve written it up accordingly.
