I have found on older Stogers that the lug will develop a lip or ridge that the latch hits and stops on, not letting the latch go all the way. Make sure that the lug is smooth all the way over the area the latch slides on. If that is not the case then the spring (even though it is a new one) may be too weak to keep it closed upon recoil.

Ask the TO to put his hand on your shoulder and when he presses the button remove his hand at the same time.

No call if not cocked. First pistol does not have to return to leather until shooting string is over before next gun type is shot.
