There is a reason why this and all the other hundreds of "oddball guns" fell by the wayside. They were either undependable, hard to manufacture, too costly or just too oddball. When this gun was conceived it was an era when a premium was placed on dependability with cost effectiveness. You wanted an affordable gun that worked because generally your life depended on it. Colt, Remington, S&W and some of the other smaller gun makers of the era provided a product that meet these criteria. If you needed more shots, just buy a second gun. I daresay that two regular six shot revolvers cost less than this gun and were probably a lot more dependable.
