What is the role of the trigger on a gun?

The role of the trigger on a firearm is to fire the gun. When the trigger is pulled, it releases the hammer or striker, which then strikes the firing pin and ignites the primer of the cartridge. This action initiates the chain reaction that fires the bullet from the chamber of the gun. Understanding this function is crucial for safe handling and operation of firearms, as it emphasizes the importance of trigger discipline and control to prevent accidental discharges. Recognizing the specific purpose of the trigger can also help a shooter in developing proper shooting technique and ensuring safety during practice and competition.
