No, @jumpinjoe , you're right. I was going off of memory as I didn't have the gun with me. I wanted to say two, but it seemed four would be more solid than the two so I figured I mis-recalled.
Good catch and sorry about that. I don't seem to be able to edit my note to correct it.
It is four screws. Takes about three minutes, if you go slow and not exactly a nail breaker. The zero is unaffected. I removed mine on first use, just be be sure there was no change.
I deprime before clean, also. If you use the process I mentioned, you'll likely find you no longer need the tumbler polish. Shiny inside and out when dry.
I have Muddy River's IWB Leather, also. It is, indeed , very comfortable. Mine is for the subcompact XD, so it is just a tad big for the HellCat, but because it is leather, not a problem.
Excellent customer service, too.
I use an IWB Kydex Holster from Muddy River Tactical, https://muddyrivertactical.com/product/inside-waistband-kydex-holster/ in 4 o'clock. They have HellCat model for both optical cut or without.
Works well.

Sergeant at Police Station: What is her height?
Husband: I'm not sure. A little over five-feet tall.
Sergeant: Weight?
Husband: Don't know. Not slim, not really fat.

Husband: Sort of...
TOTALLY agree! My approaching 70 year old eyes no longer work well with any iron sight. Optics are about the only way I'm able to consider myself to be an acceptable marksman at any level. I got the 4 moa RMSc for just that reason. (now if I can just get down the needed muscle memory to...
With ultra-sonic cleaning becoming more common, I'd like to see all manuals provide directions, recommended solutions, prohibitions, etc for this cleaning method which will obviously differ based on materials used in fabrication.
Basic cleaning only takes the gun down minimally with further...
Glad to hear you found a sight that works for you without having to modify an otherwise excellently designed gun. My Hellcat is a virtual "tack-driver" and I cringed at the idea of taking a file to one for other than ornamental reasons.
I use ultrasonic for cleaning The best solution and process I've found is from https://www.6mmbr.com/ultrasonic.html Jason Baney uses diluted vinegar and a well documented multi-step process. Brass looks new inside and out, even the primer pockets.
I'm suggesting a different sight. One Hellcat on the market, multiple red dots. If one is adamant about using a specific sight, modify the sight, or use a different gun.
I've had the same thing happen on initial outing with the Hellcat and Shield RMSc. The red dot sort of disappeared and when located, was extremely dim. After a short visual exam, I took an "iron sight only shot" and the red dot reappeared, to the already set location. This happened twice over...
