Questions & Answers
Can it fit to p365 ? Not the p365 XL.

The Sig Romeo Zero will work on the P365. It requires a mounting plate such as the Outerimpact red dot adapter.

How do I turn on the sig romeo zero? Expert Answer

The Romeo Zero works off motion activation. It will turn on when it detects motion and shut itself off after a period of time when no movement is detected. There is a small button to adjust the brightness just behind the lens that will adjust the brightness level of the optic. There is no ON/OFF button.

Helpful Positive Review Great optic by Robert, June 21, 2023
Great optic, no problem zeroing or holding zero. The only reason I gave this 4 stars instead of 5 is that the metal protective shroud that it came with did not fit the Sig Hellcat Pro. This is a Sig sight.. how do you not make a 4 hole shroud for you...

Helpful Positive Review co-whitness by Joseph Faulkner, Verified Owner, October 24, 2022
I looked at all the pistol red dot optics out there and this one had the smallest profile and fit perfectly on my Glock 43. The dot is crystal clear. One of its best features is its shake to wake ability. Just leave the sight in and it will turn off ...

Not half bad. For the price it’s worth every penny. The shake awake is it’s greatest feature besides it’s weight and size. I would definitely recommend. It also looks great but finding the right plate for it can be difficult lakeline offers one that...

Helpful Positive Review Excellent Red Dot Optic for the Money by SuperNJdad, Verified Owner, October 24, 2022
Purchased for a P365X. It was very simple to install. I would recommend also getting the matching metal shroud which I also used. There may be some which are sold as a all in one set so read carefully.

Helpful Positive Review RDS for the Sig P322 by AZShooter, November 1, 2022
I wanted to experiment with an RDS on my new SIG P322, which is RDS ready. The P322 accepts RMSc sights. The Romeo Zero at Optics Planet was one of the lower priced choices. Removing 2 screws from the factory rear, and mounting the RDS with the ...

Helpful Positive Review Sig Sauer Romeo Zero by albin, December 24, 2022
Great sight for the price dumb metal shield to protect the plastic housing looks crappy mounted especially on the FDE. Left it on the black one but took it off the FDE. Comparable to the Holosun 407k x2 but better price. I have 2 Holosun 507k on Sig ...

Product Info for SIG SAUER Romeo Zero Red Dot Sight 1x 6 MOA

Enjoy the latest and greatest in slide-mount optics with the SIG SAUER Romeo Zero Red Dot Sight 1x 6 MOA. These Red Dot Sights from the pioneers at SIG SAUER feature a 20,000 hour battery life for extended use on and off the field. With polymer housing the Romeo Zero Red Dot Sight is lighter and won't weigh down your rear. For an affordable addition to your firearm look to the SIG SAUER Romeo Zero Red Dot Sight 1x 6 MOA for high quality at a fraction of the cost.image

The ROMEOZero was designed to match the Shield RMS-c footprint. Two sets of mounting screws are included with commercial versions of the ROMEOZero - M3 screws which are meant to mount the ROMEOZero to SIG P365 optics-ready slides, and M4 screws which are meant to mount the ROMEOZero to certain pistols that have slides cut for the Shield RMS-c footprint. SIG Sauer does not recommend mounting the ROMEOZero to Springfield Hellcat pistols, as the Hellcat design does not allow for a sufficient amount of thread engagement with the optic mounting screws. SIG Sauer assumes no liability if a user attempts to mount a ROMEOZero to a Springfield Hellcat pistol slide. Customers are encouraged to contact their firearm's manufacturer for guidance on compatible optics products and specific installation procedures for their firearm.
