Thanks for all of the hard work to compile this info.It's awesome to have this resource to refer to!

I do have a question that I'd appreciate any info anyone can share. I have one of the Hank Sloan model Buchiemer holsters. It is marked "HS 7" on the back side. I assumed that these were most likely offered just for S&W K frame 4" guns, but my new holster is a really snug fit on my Model 15 and that only comes with the adjustable welt adjusted all the way out. My Cobra is a better fit,although it might not be as snug a fit as I would want.

Does anyone know what the "HS 7" is supposed to fit? Thanks in advance!
