if you heat up the kydex with a heat gun you can lay it on the law giver and press it in to all the shapes and mold it, just like vacuforming without the suction. after you get the shape molded, trim it to the movie prop shape.
I finished it up with a few rivets attaching it to a budget drop leg holster from ebay ($20.00) It's not cannon ,but it will due until I rework the buckles ,
I don't think I'll attempt a run but I'm sure someone else will..
