SIG SAUER Romeo Zero

Sig Sauer ROMEO Zero Micro Reflex Sight – Ultra-Compact Red Dot for Everyday Carry

Fast targeting. Compact design. Proven reliability.

The Sig Sauer ROMEO Zero is an ultra-compact, lightweight micro reflex sight built for concealed carry pistols, especially those equipped with the Shield RMSc footprint. Ideal for EDC use, the ROMEO Zero offers fast target acquisition and enhanced accuracy without adding bulk, making it a top choice for defensive and competitive shooters alike.

Designed specifically for micro-compact handguns like the Sig Sauer P365, P365XL, and similar optics-ready pistols, the ROMEO Zero features a rugged polymer housing that’s tough enough to handle daily carry and harsh conditions. The scratch-resistant Spectracoat™ lens system provides a clear sight picture, while the 6 or 3 MOA red dot allows for rapid sight alignment, even under stress.

Powered by a CR1632 battery, the ROMEO Zero delivers up to 10 years of battery life, depending on usage, and features Motion Activated Illumination (MOTAC™) for instant-on performance when movement is detected. Eight adjustable brightness settings ensure visibility in all lighting conditions—from bright daylight to low-light defense scenarios.
