Milt Sparks makes a few holsterss for wheelguns

select Products then All Other Holsters
The only model they make with the crossdraw cant is
the #HSR aka Hackathorn Special/Revolver
I have the #200AW with the Lined option - instead of making
the holster out of one piece of 12 oz leather with the rough side in,
the Lined version is two pieces of 6-7 oz leather with the rough sides
blued together, so the gun resides with smooth leather, as you will
read in the description, it has a tension screw that is tapered and will
not back off, mine has the Basket weave but the Decorative stitch looks
pretty good too for "going to town." Mine is built for a 4" Bbl. L-frame
and with a vest/light windbreaker ccws.
I'd also advise to get one of the MS belts 1 1/2" to support the heavy N-frame you have. I got one, and another for my son-in-law who works construction and hangs stuff on his and sez it's the best belt he's ever had
as is mine.
