Sig Sauer ROMEO1PRO 1x30 Reflex Sight, 3 MOA Red Dot, Black, Steel Shroud, 1 MOA Adjustment$349.99
Availability: In Stock
The Sig Sauer ROMEO1PRO is a compact 1x30 reflex sight built for shooters who demand reliability on defensive and duty handguns. With its 6 MOA red dot and steel shroud, this miniature open-reflex sight delivers fast target acquisition and the durability to handle real-world use—whether you're running your duty M17, P320, or any pistol with a PRO-cut slide.
Built from aircraft-grade aluminum, the ROMEO1PRO resists corrosion even in harsh field conditions. The molded glass aspheric lens and its high-performance coatings eliminate distortion and maximize light transmittance, so you get a clean sight picture whether it's broad daylight or low light. The point-source emitter offers 12 brightness settings—10 for daytime shooting and 2 for night vision compatibility—with over 20,000 hours of runtime, so battery anxiety isn't part of your carry equation. Motion Activated Illumination (MOTAC) powers the sight on when movement is detected and shuts it down when the gun sits still, stretching battery life in the field.
Recoil is part of handgun shooting, and the ROMEO1PRO handles it. The TruHold Lockless Zeroing System uses twin adjustment springs engineered to absorb recoil and return to zero shot after shot without mechanical creep. Waterproof to IPX-7 rating (full immersion to 1 meter) and fog-proof, this sight keeps working in conditions that would stop lesser glass. The included steel shroud wraps the electronics in extra protection, and the easy-access battery compartment means field changes take seconds.
If you're mounting this on a PRO-cut slide—whether it's a Sig or an aftermarket gun—the ROMEO1PRO fits the bill. Note that it's designed for PRO-cut optics and is not compatible with slides cut for the standard ROMEO1.
