This ROMEO1 Miniature Reflex Sight from Sig Sauer Optics is a valuable addition to any handgun, whether it be competition, home-defense, or concealed carry. While the ROMEO1’s size makes it ideal for pistols, the red dot sight allows for quick target acquisition when used on modern sporting rifle platforms like the AR and AK variants. The reflex sight uses a 3 MOA dot with 5 daytime and 2 night vision settings producing a brilliant dot in all lighting conditions. The ROMEO1 Reflex Sight is designed to handle long term exposure to handgun recoil while still maintaining its zero, even with stout loads like 230 grain .45 ACP.

The ROMEO1 is outfitted with Sig Sauer’s MOTAC™ technology that automatically turns on the reflex sight when it detects motion and shuts the device down when it doesn’t. MOTAC™ doesn’t only save you battery life but it ensures that the ROMEO1 is activated when drawing your weapon; saving you valuable time. The ROMEO1’s housing is built from CNC Magnesium, making the red dot sight lightweight and highly durable ensuring many years of service.

While I am still getting used to this optic (first on a handgun for me), I am pleased with the performance so far. This is the only optic that will fit the gun on which it currently resides without a modified slide, and I wanted to have one before they may be discontinued. As of this review, I do not regret that decision.
