It can't be done on my Uggy, which does have an automatic safety and does not have a lever that latches over.
The safety is being pushed on at opening and there is no way to pull the triggers with the safety on.
I prefer the Darne method-close action, pull triggers, put gun away. No snap caps or other kludge needed.
Best,
Ted
This is also an accepted method of de-cocking a Fox. No harm done to a Fox by dry firing it.
I, however, never de-cock any boxlocks I own. Releasing
some of the tension on a spring, by de-cocking it, is not something I am concerned with. De-cocking, or dry firing, does not release all spring tension, just some of it.
