Sig Sauer Electro-Optics Sor21301 Romeo2 Black Anodized 1X30Mm 3 Moa Red Dot Reticle Fits Pistols (Pro Rx Footprint), Features Large Shroud

The Sig Sauer Romeo2 red dot sight with large shroud is a compact, enclosed optic built for carry and duty use on any Sig pistol with the PRO-cut slide. This 1x30mm reflex sight delivers fast target acquisition with its 3 MOA red dot reticle while the full-length steel shroud and enclosed lens system protect the emitter and glass from dust, debris, and moisture in the field or at the range. It's the kind of straightforward, durable optic that works hard without demanding attention—no-nonsense glass for shooters who need their pistol ready whenever they are.

The Romeo2 uses a high-efficiency LED emitter paired with a molded aspheric glass lens and Sig's high-performance red notch reflector coating to deliver a bright, distortion-free sight picture across 12 daylight and 3 night vision brightness settings. Two smart features save battery life: MOTAC (Motion-Activated Illumination) wakes the optic on movement and powers down when still, while MAGNETAC automatically turns it off when holstered and back on when drawn—a game-changer for users who prefer passive retention. The 7075 aluminum housing and steel shroud shrug off hard impacts, and a CR2032 battery good for 25,000 hours at medium brightness means you're not hunting for spares mid-season.

Installing the Romeo2 is straightforward: it mounts directly to any Sig PRO-cut slide with no adapter needed. Battery changes happen via a side-mounted tray without removing the optic, and the sight features full elevation and windage adjustment (100 MOA in each direction) for zero work at any distance. Sig's D.A.R.C. technology also plays well with gen3+ night vision devices if you run thermal or NV hunting rigs. Built, tested, and assembled in the USA, this is glass that earns its place on a carry or duty gun.
