If the pic is of the right gun, it's not a revolver. It's more akin to a derringer. Although, it's the first derringer I have seen with a trigger guard, not a bad idea though. Derringers are typically single action which means this dude was either sleeping with a cocked gun under his pillow or he inadvertently set it off while cocking it. Dumb acts both....
