I'm looking for a used OWB holster for my Smith and Wesson 637 Airweight with 1 7/8" barrel. Preferably leather. I like the pancake style, like the Simply Rugged Sourdough Pancake, or something a little smaller. I would prefer something without clips or straps - only belt slots, because it seems to hold tighter against my body. Let me know what you have. Thanks!
