I always loved the gunfighter revolvers, never quite bothered to get/make one, but I mean things like this:
Which were legit fighting tools for a time, the pinnacle of revolvers being carried, in say the early 80s, before everyone admitted technology has moved on. Well, except GIGN but let's ignore them for now. Matte black, bobbed hammer and either DAO or deeply tuned to optimize the DA pull. In .357 if you must, but often shooting .38 +P specifically for better followups, less deafness. Low profile sights; a few did custom stuff, I have seen Novaks on a revolver even! Tritium fronts, etc. Because gunfights happen all the time.
Updated to today I'd say the Kimber K6 TLE is getting close to that ideal, something optimized for coming out of holsters, and shooting straight, very fast. Tactical doesn't mean rails or anything.
I LOVE RDSs, think they are by far the best thing you can do to assure hits, faster, in all situations. But if you are going with a revolver, I am not sure there's a way to put a dot on that is wholly compatible with optimize carriage methods, or being the classic level of anti-snag. But I can think of half a dozen people doing revolver-dot projects now, be interesting to see what comes of those that are carry/combat (vs competition, range) optimized.
