If you're thinking of getting into a Kydex project like making a holster, KnifeKits has a 'scratch & dent' deal going. The mailman just delivered a couple sheets and I'm really not sure what the flaws are supposed to be. It's $2.82 per 12"x12" sheet, so even with $8 shipping it's like half what they wanted at the Tandy Leather store. (Who are super nice and helpful; I'll probably go back there for some hardware.)
I got this .093" thickness based on my experience that the .06" material of my current holster has developed a crack after a couple years of use. Oh, and when I went to look up the info on my current holster, I found that it's the top 2 hits for a Google search on "GP100 Minotaur". So I feel important.
