I think the other one I saw, more than ten years ago, had a ring trigger. I thought it was a double action type trigger like on many pistols. Pulling it cocked it and then pulling it further tripped it to strike the primer. As to game wardens it would be a simple thing to block one chamber off to be legal. If my good friend Stan would buy this for his farm use, I’m sure I’d get plenty of opportunities to use this double-double and understand its operation more clearly. At 7 pounds, 7 ounces I expect it swings well with most of the weight between the hands.
