Sig Sauer Romeo-X SIG-LOC Compact 3 MOA Reflex Sight

The Sig Sauer ROMEO‑X SIG‑LOC Compact is an enclosed pistol reflex sight engineered for low deck height co-witness with standard-height iron sights. It uses the SIG‑LOC mounting footprint and is designed for compact pistol integration, with a 3 MOA red dot option and a 1x/24 mm optical system for a fast, unobstructed sight picture suitable for everyday carry and duty-style applications. Note: currently the SIG‑LOC mounting footprint is only slide‑compatible with the P365‑FUSE; broader integration across P365 and P320 platforms is indicated as forthcoming.
