How many safety mechanisms does the weapon have?

The M9 service pistol is equipped with three primary safety mechanisms, which work together to enhance the firearm's overall safety profile. These mechanisms include:

1. Manual Safety: Positioned on the slide, this lever can be engaged to prevent the trigger from being pulled, effectively ensuring that the weapon cannot be fired unless the safety is disengaged by the operator.

2. Firing Pin Block Safety: This feature prevents the firing pin from moving forward and striking the cartridge primer unless the trigger is fully pulled. It means that even if the pistol is dropped, the firing pin cannot lead to an accidental discharge.

3. Decocker: This allows the shooter to safely lower the hammer from a cocked position without firing the weapon. When the decocker is used, the hammer is lowered, but the trigger is disengaged, ensuring that the weapon remains safe during this action.

Understanding these safety mechanisms is crucial for safe handling and operation of the M9 pistol, as they collectively minimize the risk of accidental discharges under various conditions.
