Since you mentioned concealment I'll throw in some of my experience carrying a 4" N-frame for several years.
I'm rarely in a non permissive environment and I'm self employed and dress however I choose. I have carried a 4" N frame in NPE, but a 1911 or a 3 1/2" 1911 are of course easier. Open carry is a very, very common thing to see in my part of the world, no one cares, so there's that factor as well.
I carry my revolver OWB 98% of the time.
High & tight rule the world for me. Low holsters put the bottom of the holster way out in the open. Butt away from the body tents the gun (I roll with full size grips almost always).
I'm not anal on concealment as I don't have to be here, If I stop at a gas station and my gun is out for the world to see, nobody cares.
But in town I prefer to pull my shirt over the gun. I've lived/worked in Carhart T-shirts for decades. Carhart went woke so they are out for me, other good options are available tho.
I carry at a minimum 2 reloads. The Safariland CD-2's look fragile and not secure, but I've carried them forever with no lost speedloaders unless I put them behind the holster where "some" chairs will flip them onto the ground/floor. In front of the holster, all is good. On my motorcycles, in any chair, at church, no matter.
High riding holsters for revo's are harder to find (remember, t-shirt should cover). You can tell in pics on the net, where the cylinder will ride in relation to the top of the belt slots. Most are too low for my use/clothing.
Butt tucked in tight is also a harder thing to find, most people who carry a large revolver only do so in the wild, they don't care about high & tight.
I find very little difference between carrying a K frame, a L frame, or an N frame under my shirt. The thickness is relatively small.
Many people in internet land love the Simply Rugged pancake holster. I can only guess that they do much less draw practice than I do. That holster (and all pancakes) tend to collapse when the gun is out of the holster. That's a no go from me.
Pancakes as a rule also take up too much belt space (for my use). I keep my reloads just in front of the holster taking advantage of the shadow under my t-shirt that the holster has already created. So I want a smaller on the belt profile, extra leather is in my way. The "Avenger" style holsters also help here.
The Mernickle (that's my best option to date) I usually carry with the "cross draw" loops thru my belt, strong side, just in front of 3 o'clock, 2 speedloaders in front of that, another speedloader and/or a belt slide (6 rounds) on my left side. The cross draw loops put the gun in a very slight backward cant but raise the bottom of the holster a considerable amount. I use the rearward cant loops if I'll be driving all day as it unburies the butt from the seat and makes acess easier.
Sorry I wrote a novel, may be some of it might be helpful to folks wanting to all day carry a revo. Maybe not
ETA: shoulder mobility is a serious factor with High & tight holsters, I do have to contort just a bit to draw the gun but nothing troublesome. Cant is also affected by shoulder range. I live very rural, and draw my gun several times per day as I stroll around just for practice, sometimes for real as the coyotes/skunks/etc are thick this year. I've taken the belt off my rucksack to clear my holster. I ruck for fitness so it's no prob making things harder
Your world may well be different than mine.
