It is possible to decock the Ideal by holding the spur to the stock grip and depressing the triggers.

Slowly returning the spur will let the strikers down on the primers. There is no rebound action in the Ieal. The strikers protrude when in the fired/uncocked position. In effect the pins will be touching the primers.

Personally I would not do it.

Also, squeezing the spur on flush involves compressing three springs, the opening lever spring, plus two main springs. Can it be done quickly enough and leave time to swing on a bird?

Isn't it easier to use the safety or carry the gun open?
