SIG SAUER Electro-Optics is pleased to introduce the all-new ROMEO1PRO Open Reflex Red Dot Sight. The ROMEO1PRO is capable of mounting to any pistol with a SIG Sauer PRO slide cut, and is crafted for durability, and for use in harsh environments.

“The ROMEO1PRO is the latest evolution of the ROMEO1 sights and brings a new level of durability and performance to the open-reflex red dot sight,” said Andy York, President, SIG SAUER, Electro-Optics. “The adoption of a red dot sight on pistols is becoming the standard in the commercial, law enforcement, and military markets, and the ROMEO1PRO is the ultimate solution for fast, responsive target acquisition and accuracy combined with the easy mounting option of the PRO footprint.”

    why are reflex red dots increasing in price instead of reducing in price? Even the supposed gold standard the trijicon rmr has its issues from lens clarity to durability and the newer gen 2 is still ridiculously priced.

    At least when Trijicon released the SRO they had the wherewithal to keep the same mounting pattern.
