My suggestion is a Threepersons holster from El Paso Saddlery. I own several and they are excellent holsters. You can get them plain or with different degrees of stamping or carving. Lined with pigskin to protect a gun's finish and available for several different belt widths.

I think they are reasonably priced, but there is often a wait time of four to six weeks before you get your holster from them. So if you're in a hurry...well, probably should look somewhere else.

Other custom makers offer shorter wait times.

There are several members of this forum who do outstanding custom leather work.
