Hello,
Yes they are rare. The original ones are few and far between as the company went broke after about a year or so. Originally, every gun they sold, they LOST about $1000.00 as production costs were so high, but the owner wanted it to be priced lower. He thought that as production went up, the learning/productivity curve would kick in and bring the cost of manufacturing per unit down. Never happened. A few companies made versions of it in the same and different calibers over the years. 44 Automag ammo is a rare bird too. But I think there is a company or two making it. There is also a company making brass for it too.
