SEMI-AUTO

The most common handgun is the semi-automatic pistol. Unlike a revolver, a pistol has a single chamber integrated with the barrel of the gun that is fed ammunition from a box magazine. The semi-automatic action is named as such because with each trigger pull it fires the round in the chamber, ejects the leftover casing and then loads a new round every time the trigger is pulled. A hammer does not need to be cocked and a cylinder does not need to rotate. The upper portion of a semi-automatic pistol is called a slide which houses the barrel and guide rod spring. The box magazine that holds ammunition feeds bullets into the barrel via the magazine spring.
