I'm not sure if you're looking just for OWB or if IWB is acceptable, but I carried a 3" 65 IWB in a Milt Sparks Summer Special II and it worked quite well. I also had an IWB holster based on the Milt Sparks VMII (made by a company that is no longer in business) that worked well; I'm sure there are others of that style.
I'm generally not a fan of OWB carry and don't have any experience carrying a revolver in such a holster. In general, though, I can recommend Side Guard Holsters. They make good quality holsters at a decent price. I consider them a good value.
