Which safety feature is designed to prevent the firing pin from moving when not intended?

The firing pin block is a critical safety feature designed to prevent the firing pin from moving unless the trigger has been pulled deliberately. This mechanism ensures that the firearm cannot accidentally discharge due to jolts or impacts, which enhances the overall safety of handling and operating the weapon.

When engaged, the firing pin block physically obstructs the path of the firing pin, meaning even if the trigger is pulled, the pin cannot move forward unless the safety mechanism is disengaged. This is particularly important in preventing unintentional discharges, making it a vital feature for responsible firearm use.

Other safety mechanisms, such as the half cock safety notch, serve different purposes and may not provide the same level of protection against accidental firings under certain conditions. A trigger lock is a separate device that can secure the firearm and prevent its use altogether but does not inherently prevent the firing pin's movement when the gun is ready to fire. The slide stop is involved in the operation of the firearm but does not specifically prevent accidental discharges by controlling the firing pin's action.
