Which part is not found on a pistol?

A stock is a component typically found on rifles and shotguns but not on pistols. The stock is designed to provide support and stability for the shooter when aiming and firing the weapon. In contrast, pistols are designed to be held with one hand, which is why they do not have a stock.

On a pistol, other essential components such as the hammer, which strikes the firing pin, the trigger that releases the hammer, and the barrel that directs the bullet's path upon firing are all present. Understanding the function and characteristics of these parts is critical for safe handling and operation of firearms, especially in a hunting context.
