The SIG Romeo-X Pro is the company's full-size enclosed-emitter pistol red dot, and this version uses a green circle-dot reticle with the SIG-Loc mounting interface. Enclosed emitters solve the problem that has plagued open reflex sights on carry guns: rain, lint, and debris cannot land on the lens and block the dot. The circle-dot reticle gives you a fast outer ring for close work and a precise center dot for distance, which is the most versatile pistol reticle available. Green is easier for most eyes to pick up quickly than red, particularly in bright daylight.
