There was a resin cast shell of an anime gun that I was trying to track down again as I'd had it in the past and sold it. It was something like Subarau? It was a pistol with a square shaped shroud that fit over the front, and there was a curved piece that connected from the bottom of the grip up to the back of the receiver. It was designed to go over an existing pistol of which the kit also had a resin cast. Can't think of search terms to get anywhere close so I've given up on my google fu searching. Figured someone here had to know.
