Looks like Bladetech also makes them.
www.blade-tech.com/frontend?command=HomeI own several blade tech holsters, they are a very nice quality holster.
That being said I would not use one for a 97B due to its high polish blue job.
My kydex holsters have worn the blue off of my gun quite a degree.
I know Tim Wegner the owner of Bladetech well, I knew him when he started out in the holster business. You actually need a gun mold to make a holster, just using a gun can harm it. True with leather and kydex holster manufacturing, I also know Greg Kramer a smidge too,lol. Although he probally doesnt know me from adam.
If I were to get a holster for a 97B I would go with a lined holster to ensure that the blue is not abraded.
Nicest one I know of off the shelf is the Galco Phoenix, but it is not being made for the CZ line up, too bad.
