What mechanism does a slide or tang safety use to block firing?

The mechanism of a slide or tang safety that blocks firing operates by blocking the firing mechanism. This safety feature is designed to prevent the trigger from moving the firing pin or hammer, ensuring that the firearm cannot discharge unintentionally. When the safety is engaged, an internal component physically obstructs the operation of the firing mechanism, allowing the user to handle the firearm safely without the risk of accidental discharge.

A physical barrier in the barrel does not pertain to how safeties function, as it relates more to ensuring that a projectile cannot exit the firearm. Disconnecting the trigger from the hammer is a different type of mechanism often found in more complex systems rather than the straightforward operation of a slide or tang safety. Preventing bullets from entering the chamber involves aspects of firearm design separate from the functioning of safety mechanisms. Understanding these distinctions is crucial for recognizing the importance of the safety feature in preventing unintended firing.
