Budget, tastes, carry...
Depending on your budget range, tastes, styles etc, there are many top notch holster makers & leather shops that could fit your need(s).
Id suggest contacting the firm first to insure they can design or craft a holster they way you want & you know how long or when you can take deliver.
Due to high demands & the increase in gun ownership in the last 4/5 years, some holsters may be delayed for long periods.
For a crossdraw DA revolver, see; Don Hume, Galco, Tex Shoemaker, El Paso Saddlery, Greg Kramer, Milt Sparks, Bianchi-intl, Kirkpatrick Leather, DeSantis.
Kramer offers horsehide(which Id suggest).
Some makers offer field holsters that can be used cross-draw or strong side.
Id suggest a decent leather or lined gun belt too. A 4" N frame will be a lot of weight on your hip(s).
