Since you are talking about a 5" N Frame, in Texas my guess is this is an open carry holster.
The El Paso Saddelry Street Combat style should work good if you are just walking around.
If you ride horses, and do things that bounce you around I would go with a thumb break retention holster like a Bianchi 5 BHL.
I have them in 4" K Frame, 4" N Frame and 6" N Frame sizes. They are just a good well made utility holster.
