Safe Action System
GLOCK’s revolutionary SAFE ACTION® System provides a consistent trigger pull from the first to the last round. The three automatic independently-operating mechanical safeties are built into the fire control system of the pistol.
This safe, simple, and fast system allows the user to concentrate fully on shooting without having any additional actions to disengage and reengage safeties. This means it is safe if it’s dropped, and additionally it functions at temperatures from -40° to 122° Fahrenheit.
How Does it Work?
The SAFE ACTION® System is a fully automatic safety system consisting of three passive, independently operating, mechanical safeties. All three safeties disengage sequentially as the trigger is pulled and automatically re-engage when the trigger is released.
The trigger safety is the first safety in the firing sequence. It’s incorporated into the trigger in the form of a lever and when it is engaged 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.
The trigger safety is designed to prevent the pistol from firing if it’s dropped or if the trigger is subjected to any pressure that isn’t a direct firing pull.
WARNING: If the trigger is in the forward position the pistol may be loaded.
Firing Pin Safety
The second safety, the firing pin safety, mechanically blocks the firing pin from moving forward in the ready-to-fire condition. As the trigger is pulled rearward, the trigger bar pushes the firing pin safety up and frees the firing pin channel. If you decide not to fire and release the trigger, the firing pin safety automatically reengages.
The final safety involves the trigger bar, which rests on the safety ramp within the trigger mechanism housing. The trigger bar engages the rear portion of the firing pin and prevents the firing pin from moving forward. As the trigger is pulled rearward the trigger bar lowers down the safety ramp and allows the release of the firing pin. After firing, the trigger bar moves upward and re-engages the firing pin. As the trigger is released, all safeties automatically reengage.
Firing Sequence / Trigger Reset
A special feature of the SAFE ACTION® System allows the trigger to reset with only limited forward movement of the trigger, so you don't have to completely release the trigger in order to fire a second controlled shot or when you need to fire several rounds quickly. After a round is fired, you only have to release the trigger until it resets, which you can hear and feel.
All three pistol safeties automatically re-engage when you release the trigger to its forward position.
