As the title suggests, I'm looking for an IWB holster for a Model 36. Specifically, a 2" Chief's Special. I know there are many out there, but specifically I need a holster that is a clip-on, and with enough material on the backside to shield my "girth" from the metal of the hammer. But, even more specific, I would require some type of retention device. Such a short barrel does not lend itself to always staying tucked in. I'm thinking along the lines of a thumb break. Does anyone have any suggestions without having to go the custom route?
