The Sig Sauer Romeo-RS Pro is a 1x31mm pistol-mounted red dot designed for shooters who want a modern optics solution without the premium price tag. Built in Tualatin, Oregon, this compact sight combines a rugged steel chassis with a molded polymer housing to deliver durability where it counts. The hybrid construction gives you the strength needed to handle the recoil of centerfire pistols while keeping weight down—it tips the scales at just 0.94 ounces with battery installed. If you shoot a P320, P226, P229, or any optic-ready pistol with the PRO cut slide, this is engineered specifically for your gun.
Accuracy and usability are baked in. The molded glass aspheric lens gives you a distortion-free sight picture, and the 6 MOA red dot cuts through glare and low light. Eight brightness settings let you dial in the glow that works for your environment, and the Motion Activated Illumination (MOTAC) technology powers the dot when you move and shuts it down when you don't—stretching battery life to 20,000 hours at medium brightness. The CR1632 battery loads from the side of the optic, so you never have to unmount it to swap power.
Sig's updated PRO footprint maintains true compatibility with industry-standard optics cuts and uses steel recoil pins to lock up tight and eliminate lateral shift. The side-mounted control button sits flush in the polymer housing to prevent accidental adjustments. Whether you're running it at the range or carrying it on duty, the Romeo-RS Pro is backed by Sig Sauer's Infinite Guarantee and built entirely in the USA.

The Romeo-RS Pro is designed for the P320, P226, P229, and other optic-ready pistols with the PRO cut slide. It is not compatible with pistols cut for the original ROMEO1 footprint. If you have an optic-ready P365, Sig Sauer offers the Romeo-RS Compact instead.
At medium brightness with the dot-only mode, the CR1632 battery delivers a minimum of 20,000 continuous hours of runtime. The MOTAC system extends this even further by powering down the dot when no motion is detected.
Yes. The Romeo-RS Pro uses a convenient side-load battery tray with a security screw that allows you to swap the CR1632 battery while the optic remains mounted on your slide. Your zero will not be affected.
The reticle is a 6 MOA red dot.
