The Cameleon was a concept revolver designed by Czechoslovakian ice rink technician Karel Michalek. Michalek had wanted to make his own handgun, but was limited by government restrictions. In 1989, Michalek decided to construct a concept gun out of wood and epoxy resin.
I think it’s just a proof of concept mockup and not meant to be functional.
I don’t think there’s an epoxy wonder-material on earth that would withstand the chamber and barrel pressure of a .44 magnum, and even if it did you’d still have rifling in it for about 0.2 nanoseconds.
