Guys, believe it or not Glasshartt can probable make one of those if you had the seat frame to mount it on. She re-builds saddles and does leather work and is getting ready to start making holsters. It would be expensive though. She makes one hell of a gun belt for jeans or dress pants. She made two for me one of each that is great. If anyone wants to see her work let me know and I will post up some pictures of her work. She also makes customs chaps (horse).
