A couple of El Paso Saddlery Three Persons and a Ruger Bianchi Flap holster. I think the way the revolver is positioned in the TTP holster helps to minimize contact with the rear sight.
When better protection is needed this Ruger/Bianchi Flap holster gives pretty good coverage for the revolver and grips. Not a bad way to go.
Some grips you just want to give some TLC to like this Bowen tuned Old Model .45 Colt with Sambar Stags.
