Style: 3 MOA Red Dot - Black
I just mounted the SIG SAUER Romeo-X Enclosed Compact Pistol-Mounted Reflex Sight (Circle Dot version) on my P365 Legion, and it's an absolute winner. If you're looking for a rugged, reliable enclosed emitter optic that doesn't compromise on performance, this is it. The fully enclosed and sealed design is a huge upgrade—dust, rain, lint, or debris can't interfere with the emitter like on open reflex sights. It's built with tough 7075 aluminum housing and an aspherical distortion-free glass lens that's crystal clear edge-to-edge. No fisheye effect, no tint—just a sharp, crisp reticle (I love the 32 MOA circle with 2 MOA dot for quick acquisition). The ultra-low deck height is genius; it co-witnesses perfectly with standard iron sights without any riser. Mounting was straightforward on the RMS-c footprint—no adapter needed. Side battery compartment means no re-zeroing when swapping the CR1632, and with MOTAC motion activation plus 20,000+ hour runtime and 15 brightness settings (including NV), it's incredibly practical for EDC. It's held zero flawlessly through hundreds of rounds, feels premium, and the patent-pending beryllium copper flexure makes it bombproof. Assembled in the USA with SIG's Infinite Guarantee? Peace of mind. If you want mil-spec toughness in a compact package for concealed carry or duty, the Romeo-X Enclosed Compact delivers big time. Highly recommend—worth every penny!

Style: 3 MOA Red Dot - Black
A fantastic Red Dot for a P365X from Sig Sauer. As this was my first Red Dot ever, it took a little getting used to. I went to the range to manually "zero" it in. As it comes with the tools needed to do so, the process was very easy. However, as my first Red Dot, I had a difficult time zeroing in at the range. The next day, I ordered a MidTen Green Laser Bore for zeroing in a laser bore. Took my sidearm back to the range and between Sig Sauer's unparalleled quality, and the help from the laser bore, I was shooting in tight groupings, and hitting my targets with a newfound ease. This Red Dot also has a lifetime warrant - as do all Sig Sauer's shooting products. A little on the higher priced side, but you get the quality to justify it. More important, while I hope I NEVER have to draw my weapon, if I do it's good to know it is SO accurate. After all, do you really want to save a couple of hundred dollars on a cheaper Red Dot, especially when you (or your loved ones') life may be on the line? The Bottom Line? Uncle Steve Approved!

Style: 3 MOA Green Dot - Black
Works flawlessly so far. I have this mounted on my P365 XL. I’ve put about 400 rounds (147gr) at the range with this optic and so far it’s held zero perfectly. The low deck height allows near co-witnessing and the MOTAC seems to work as designed.

Works Great! Mine does not seem to have the battery issues that others have had. The adjustments are crisp and tactile, and the glass is clear. I started with the open emitter version, but after a day of mowing a property, I decided the enclosed would be better. The open is hard to clean the glass. There is no worries with this one. If you are on the fence, get the enclosed. It is just slightly longer but you can't tell. It is worth the extra money for the cleanliness and ease of maintenance.

Amazing for a company like Sig to send a brand new red dot and it won’t even turn on out of the box. I guess I’ll have to switch back to the Holosun that actually works. Awesome quality control fellas!!! 👎🏽

Style: Red Circle Dot - Black
Exceptional. At first I tried the circle dot and like it a lot, but changed to the single 2 MOA red dot. Since I shoot 300-700 rounds per month, my automatic eye capture on the red dot is already second nature and the circle dot was a little more confusing to me during quick shots. I would recommend the circle dot for those new to red dot optics. It is easier to initially capture and align with the sight picture. The side buttons make it easy to switch between reticles and brightness. It mounted flawlessly on my concealed carry S&W Shield Plus Performance Center 4" as expected and the low deck allows for clean co-witness of the original iron sights. I was debating between the Holosun or this Sig. The lower deck was the decision maker. Zero regrets.

Usually I only do aimpont or trijicon, but if this thing is reliable long term it is amazing. Right out of the box on my glock 48 it was right on. It has blue tint, I've seen every manufacturer have that, it does not bother me at all. You can cowitness irons, perfect height, its enclosed, looks good. I've had many optics and I love this thing. Really happy they did RMSc footprint.

If you even wipe the glass with the most basic of cloth, it will immediately get fine scratches. Comically fragile. The red dot image itself is solid, but the glass issues make this not even a contender. Better off with Osight SE.
