The sight itself is great. I've read reviews against the adjustment increments, that they don't provide enough feedback and are not in 1 MOA increments, but with the disc provided to assist in adjustments, I was able to zero it in 12 rounds (4-by-3). I chose the 8 MOA for quick target acquisition as this was for my bedside home defense pistol.

I chose this for my P320 X-Compact 9mm, but that wasn't the best decision on my part. Yes, the RMSc direct mounts to the x-compact, but it does not adequately fill the machined footprint. It does adequately cover loaded chamber indicator and allows it to function properly. But, the RMSc is too small for the x-compact. It doesn't cover the holes from the removed sight-plate screws, and I don't want anything getting inside the slide to the extractor spring pin. I do not recommend the RMSc sight for the P320 x-compact platform. I now have a great excuse for a second Hellcat, but an OSP this time as the RMSc mates perfectly with that platform.

The 8 MOA, zeroed in, allowed me to keep a 2" grouping at 15 yards. I'm a novice and this is a 3.6" barrel pistol, so I'm happy with that accuracy, especially for that gun's intent (I've since replaced with a Sig Romeo1 Pro 6 MOA with identical results). Hopefully I will see similar results with the RMSc on a Hellcat, even with a shorter barrel.

Total novice, so take it for what it is. I took a risk and bought a 2nd M-SPEC for my new AR pistol before I even had a chance to zero/test my first one on an AR rifle. Hit the range yesterday, and they performed perfectly as far as I can tell. Only needed 9 rounds (3x3) each to zero, albeit at 25 yards at an indoor range. I'd like to fine-tune them on a 100 yard range, hopefully soon. I sent only 100 rounds through each platform after zeroing in and they held zero with no deviation noticed.

I chose this particular sight because of the circle-dot reticle. The large circle ensures I can pull the dot into view quickly and target still resides inside the circle after each trigger pull. For my level of skill and experience, this is a perfect setup. I do wish the M-SPEC had the multi-pattern reticle options to mess around with, as some SightMarks do. Also not a fan with where these are made, but I knew this going in. It's possible that I'll progress to something more high-end eventually (i.e. made in this country), but I'll probably still stick with the circle-dot pattern.

I can't imagine anyone going wrong with this sight, but maybe I need to get a few hundred more rounds through each platform before such a claim. I know I like them and believe they're a great value.
