The “Safe Action” system is a partly tensioned
firing pin lock, which is moved further back by the
trigger bar when the trigger is pulled.
When the trigger is pulled, 3 safety features are
automatically deactivated one after another. When
doing so, the trigger bar is deflected downward by
the connector and the firing pin is released under
full load. When the trigger is released, all three
safety features re-engage and the GLOCK pistol is
automatically secured again.
