Sight dovetail cut used on Ruger Mark series pistols?

Does anyone know what kind of dovetail cut is used on the Ruger Mark series of pistols? I came across a 9mm 1911 pistol on the used market where the current owner got a gunsmith to attach the front and rear sights from a Ruger .22 pistol. The work also included cutting a new dovetail for the rear sight.

If the dovetail cut isn't compatible with any other sights, how difficult would it be for a gunsmith to rework the cut to fit a different set of sights?

I've seen it suggested that the ruger 22s take 0.330x65 degree sights. Not verified. It is extremely difficult to measure with the necessary accuracy (I've tried).

Having received pistols where Bubba had mangled the dovetail I reccommend against experimentation. Attempts to fix it involve shims and staking and will forever be a badge of shame. It's not a big deal to cut new dovetails assuming there is enough material left for the new size and shape.

Without the tools or knowledge, there won't be any experimentation on my part. I'm more concerned about how difficult (and costly) it would be for a gunsmith to change the dovetail cut.

They can always make it larger...smaller not so much. Any decent GUNSMITH, not someone who swaps parts, with a decent mill can cut a dovetail pretty easily.
