I appreciate seeing makers give credit to the original designers.
Like spooter said, somebody probably has come out with something similar but ya never know. I don't think I know of anyone that has more knowledge about holster makers and their designs than Tony Kanaley at Milt Sparks. He might be able to give you some clues about similar designs and I'd say it's a safe bet that he wouldn't rip your design.
