With the striker in the cocked position - as it would be for firing - the force of the firing pin spring is actually pushing back against the breechblock and it takes VERY LITTLE momentum to cause the toggles to pop up. The striker spring pressure actually HELPS to push the toggles up. (In fact, the striker spring does more to keep the train locked when it's NOT cocked as the train has to overcome the drag of the sear and the striker spring pressure to reach the "toggles broken" point.) Turn the cannon over and tap the top of the receiver where the date is normally stamped against the ball of your palm. If the pistol had been designed for zero recoil spring tension on the toggle train when in battery and with only the striker spring pushing back on the train, the design would never have flown and it would be a long forgotten footnote in the history of firearms.

There is NO POINT in the cycling of the action from cocked and locked through opening, ejection and chambering a new round that does not have recoil spring pressure applied to the train. Even with the striker uncocked, there is recoil spring pressure being applied. It's part of the design. If that wasn't true, there wouldn't be pressure of varying weight applied to the train at ALL times by the recoil spring.
