I found my American Derringer M-1 at Prager's Gun Shop in Orlando. The owner offered to let me shoot it. Boom! . I bought the grips from American Derringer and have fired it about fifty times. You have to hit the drum center or it will deflect leaving a deep groove. It is a good hideawy with a choice of loades. I prefer to keep a shot load and a lead round in it. I don't like the price of the shot loads, so I am going to make my own with a Lee reloading kit. I recommend as a snake or human protection. It has doubled in price since then. I don't know about value now. I still recommend it . It is probably as powerful as a .44 mag snubnose revolver. Just two shots.
