kydex is interesting stuff to work with. Why not try making one yourself. Kydex by the sheet (12" x 12") costs about $5.00 and is available at many knife-making supply houses (e.g. Jantz) as are the rivets required. Instructions for how to mold it are available on the 'net (google it). Essentially, you just cut squares or rectangles to the approximate (over)size you'll need using a boxcutter, then heat in a 385 degree oven for about 3 minutes. This makes it pliable. Then you just press it around whatever you're making a holster or sheath for (tricky, 'cause it's hot). It stiffens up quickly in the molded shape. You rivet the two pieces together, do final shape and finish on a grinder or with a file, polish the edges, and you're done. I don't know if the carbon fiber grips would be adversely affected by brief contact with 385 degree heat; my guess is that it would not. Anyway, it's an interesting way to spend a couple of hours.
