It looked like a bulky belt buckle with a swastika on it, but it flipped open with two short, smooth-bore barrels that sprung out to point straight in front of you. It held two 9mm shells and they actually test-fired it.....obviously not real functional, but interesting and a small part of history.

I think I saw somthing similar to that in a movie. I think it was the vampire movie "From Dusk till Dawn"
