The Sig Sauer Romeo2 reflex sight (Sig Sauer part no. SOR21301) is a durable 1x30mm red dot optic designed for tactical and competitive use on compatible Sig Sauer pistols, built here with a large shroud for full lens protection. This model features MOTAC (Motion Activated Illumination) alongside Sig’s D.A.R.C. dark-adaptive coating technology, delivering a crisp 3 MOA red dot reticle from a 7075 aluminum housing.
