Thanks.
My plan for now is to make three or four holsters for myself. I have one revolver in particular that I want to carry on hikes and the only commercial holster I've found is a Bianchi No. 5, which is a nice holster, but it's not what I want.
I doubt that I will pursue this as any sort of commercial endeavor. From my perspective, there are plenty of custom holster makers out there, and they're making really nice holsters now.
On the other hand, I'm amazed at the demand, especially for concealed carry holsters.
