I’m with
@Coinneach . There’s an edge in favor of large square sights but people can still use the smaller sights to very good effect.
I have an old Uberti which is capable of honest 1” 6 shot groups from a bench at 25 yards. Maybe even better than that but it’ about as good as I can do with a hand held revolver. The sights
are small, but i have very good vision for an old guy and in bright sunlight I find no handicap to speak of. As a practical matter, since 1962 I’ve fired tens of thousands of round ball and bullets through this particular revolver and finding those tiny sights is so close to second nature that I can aquire its sight picture and fire in less time than almost any other pistol I’ve used.
for the Ruger, the fixed sights are very good. Smaller than the adjustables to be sure but squared away and with a nice square post in an appropriately sized notch. You can black the stainless sight and have it all.
Here’s that Uberti (John Wesley Hardin model… ;-) and a six .465” round ball over 30 grains of 3f Swiss with a dry wool 50 caliber wad, Remington #10 caps. This was fired from the tonnea cover of my truck. 50 yards.

There’ a thread on another site asking people to shoot these old replicas at 50 yards as an exercise to see what is possible and realistic, with guns of this type. (Remingtons are welcome too!)
Here’s another group fired at 20 yards offhand with a box stock Pietta.

It’s a pretty good looking pistol but not that impressive so far and sights are way down the list of reasons it’s not a great shooter.
Purty huh?
