I used to own one. It is the worse gun that I have ever owned and about the only one that I sold because it was a total POS. The 4 barrels are not regulated so the patterns, if you can call it that, is square shaped and gets larger the furture you get from the target. That's right, NONE of the barrels on mine shot to the point of aim. The grip is small so you have a pinky dangling, it is thicker than a Glock 30 with only 40% of the ammo supply, it is heavier than a Glock 27 or Kahr MK9, and it is slower to reload than any of them. It shoots a .357 and out of that short a barrel is not able to generate any velocity to make the round do what it is known for. The 125gr Remington JHP does have a HUGE fireball, impressive when shot at night. The trigger pull would not register on a scale, over 15 pounds, LONG and not smooth. The pistol uses an internal rotating hammer to hit each of 4 firing pins and it would not go BANG everytime. bang-click-bang-click click-bang-click-click click-click-click-bang There, got off all 4. See what I mean? American Derringer in Waco, Tx has the rights to make it, but the design is so bad and full of problems they decided against trying to make it work. I bought mine for $115 used and sold it off in the late 1980's for $210. If you want it for a novelty, go for it, but if you carry it for defensive purposes, it you might get killed. If you take it to the range and tell people what you paid for it you will be embarassed right off the line. It does make a good compact club though, lord knows it is heavy enough.
