The only reason I could see carrying one is as a BUG for something in the same caliber. I always figured it would help to have something already loaded while reloading a revover without clips. I don't have a Bond Arms, but I do have a derringer in the same caliber as my kinda Colt SAA clone. I always figured if they were close enough that I could shoot the derringer and if they weren't I could just continue reloading
