What is the applied safety of the Benelli M4 Super 90?

• A. Length of the firing pin
• B. Safety lever
• C. Trigger guard
• D. Manual safety

Answer: (A)

Applied safety means a passive, intrinsic safeguard built into the weapon’s mechanism that prevents discharge without deliberate action. For the Benelli M4 Super 90, that safeguard is tied to the firing pin’s design—the length of the firing pin. This dimension is set so the firing pin cannot reach and ignite a primer unless the trigger and internal sear system allow the gun to fire. In other words, even if the weapon is mishandled or dropped, the firing pin is not free to strike a primer, reducing the chance of an unintended discharge. By contrast, the safety lever, trigger guard, and manual safety are active safety features—user-controlled interfaces—whereas the fired-in pin length represents a built-in, automatic safety characteristic of the mechanism itself.
