The Sig Sauer Romeo-X reflex sight (Sig Sauer part no. SORX1002) uses a Delta Point Pro mounting footprint, giving P320, P226, and P229 family pistols cut for that pattern a direct-mount, 10mm-rated red dot option. This open-emitter model pairs a CNC-machined 7075 aluminum housing with a 2 MOA circle-dot reticle, combining a fast outer reference ring with a precise center dot for rapid target acquisition. Finished in Flat Dark Earth and featuring a side-mounted battery compartment with an ultra-low deck height for iron sight co-witness, the Romeo-X Open Pro brings Sig’s military-grade red dot design to a duty and competition-ready package.
