SIG SAUER | Romeo 1 Pro | Black

The ROMEO1PRO (SOR1P100) is SIG Sauer's 1x30 open‑emitter pistol red dot with a 3 MOA dot. Molded aspheric lens, TruHold lockless zeroing springs, MOTAC motion‑on, 12 brightness settings (10 day / 2 night‑vision), and 20,000‑plus hours on a top‑load CR1632 so you do not have to pull the optic to change the battery. CNC aluminum, IPX7, steel shroud in the box. SIG PRO RX footprint: M17, M18, P320 Pro‑cut slides, and other SIG pistols with that cut. SIG is explicit that it will not fit every third‑party DeltaPoint Pro slide because recoil‑boss dimensions vary.
