Review: Best Enclosed Pistol Red Dot Yet – SIG SAUER Romeo-X Enclosed Compact! - 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!
Review: GREAT OPTICS! GREAT QUALITY! - 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!
