Sig Sauer ROMEO1PRO 1x30 Reflex Sight - Flat Dark Earth, 6 MOA Red Dot, 1 MOA Adjust, Steel Shroud
The Sig Sauer ROMEO1PRO 1x30 reflex sight is a compact, rugged red dot optic built for serious duty on modern semi-automatic pistols. If you're running a P320 platform, an M17, or any slide cut to accept the PRO footprint, this is the enclosed-emitter sight that bridges the gap between durability and rapid target acquisition. The aircraft-grade aluminum housing resists corrosion in harsh conditions, while the molded glass aspheric lens and high-performance coatings deliver zero distortion and fast light transmission—exactly what you need when seconds count on the range or in the field.
What sets the ROMEO1PRO apart is its combination of brightness and reliability. The new point-source emitter cranks out serious output with 12 brightness settings (10 daytime, 2 night vision compatible), backed by 20,000+ hours of runtime per battery. Motion Activated Illumination System (MOTAC) intelligently powers the dot only when it detects motion, extending battery life without forcing you to manage the sight manually. The TruHold Lockless Zeroing System uses twin adjustment springs designed to handle the punishment of handgun recoil and return to your zero shot after shot—no creep, no drift.
The included steel shroud provides real protection in the field, and the whole package is waterproof to IPX-7 rating (safe for complete immersion to 1 meter) and fog-proof. Whether you're a competition shooter, duty carry, or serious recreational gunner, the ROMEO1PRO delivers the durability and optical performance that won't let you down. Easy battery access keeps maintenance straightforward, and the 6 MOA dot with 1 MOA adjustments gives you the precision you expect from Sig.

Frequently Asked Questions
Will the ROMEO1PRO fit my P320?
Yes—the ROMEO1PRO is engineered for Sig Sauer's PRO-CUT footprint and is compatible with all P320 variants including the M17, P320-M17, P320 XFive Legion, P320 XCompact, P320 XFull, and P320 Pro Series slides. Note that it is not compatible with slides cut for the standard ROMEO1 footprint.
How long does the battery last?
The ROMEO1PRO delivers over 20,000 hours of runtime per battery. With the Motion Activated Illumination System enabled, battery life is further extended since the sight powers down when it doesn't sense motion.
Can I use this sight in night vision mode?
Yes. The sight includes 2 night vision compatible brightness settings out of its 12 total brightness levels, allowing you to use it effectively with night vision devices.
What's included with the ROMEO1PRO?
The sight comes with a ruggedized steel protective shroud designed to shield the optic and enhance durability in field conditions.
