They used to throw those holsters in when you bought the gun, at least aimsurplus used to a few years back. They generally suck, at least the ones I got sucked. The back piece is made of leather but the holster and the straps were nylon, with cheap velcro that was supposed to anchor to your belt.. I never really found mine usable.
