I searched for a Buckmark leather holster a month or so ago and learned that, for whatever reason, they are quite scarce. The only leather holster I found for a Buckmark was a $50 suede-lined, extra-magazine Triple K holster from Cabela's. I thought that was a bit more than a cared to pay, especially for a mass-produced holster that I couldn't inspect prior to buying, so I bought an Uncle Mike's Sidekick for under $15. For my purposes, the Sidekick does fine. To answer your question, I think you'll have to consult a custom leatherworker to craft a flap holster for your Buckmark. I'm sure that'll cost you a pretty penny though. Good luck, and let us know if you find something I missed.
