I have a Bianchi Remedy leather OWB holster for my Taurus 85 and fits S&W J frames as well. Not sure if it would fit the extra width of the 6 shot cylinder size of 856, but it likely would with a bit of stretch (you could use the multiple plastic bag trick) or if they have one specifically made for the 856 (or same size 6 shot j frames) I would recommend it. Rides close to body.
IIRC, I believe it's made in Slovenia or someplace like that, but it fits the revolver perfectly and is made of very heavy leather. I like it a lot, and when I carry my 856 it's in this holster. I think I bought it from Amazon, who is currently offering for $28.00.
