👉 The principle weapon of a firearm, often referred to as the "main gun," is the rifle or pistol from which the majority of shots are fired. It is designed for precision and versatility, featuring a balanced design that allows for accurate long-range shooting and quick reloads. Typically, rifles have a longer barrel for better accuracy, while pistols are smaller and more compact, optimized for rapid, close-quarters combat. Both types are equipped with a trigger mechanism that fires the ammunition when pressed, making them essential tools for self-defense, hunting, and military applications.
