The Spring Trigger. A spring trigger is actually a small spring with a threaded end that replaces the hard trigger on specially made index-triggered releases. Because it bends when you pull it, the spring is very difficult to punch. Your only recourse is to keep pulling as you continue to aim at the spot you want to hit.
Trigger Safety. The trigger safety is incorporated into the trigger in the form of a lever and when in the forward position, blocks the trigger from moving rearward. To fire the pistol, the trigger safety and the trigger itself, must be deliberately depressed at the same time. If the trigger safety is not depressed, the trigger will not move rearwards and allow the pistol to fire. If the trigger is in the forward position the pistol may be loaded.
