Shotguns come in a variety of forms and can use several types of ammunition, including small pellets and slugs. Shotguns can be single or double barrel. There are hand loaded shotguns as well as semi automatic shotguns and automatic shotguns.
Semi automatic shotguns and automatic shotguns are very similar. The difference between the two lies in the trigger. Automatic shotguns require the shooter to pull the trigger one time and the gun continues to fire as long as the trigger is held down. However, semi automatic shotguns require that the shooter continue to pull the trigger. In both cases, the guns are self loading and continue to pull ammunition until there is non left or until the shooter releases the trigger.
Both semi automatic shotguns and automatic shotguns generally include ammunition magazine which is automatically loaded as the force of gas propels the ammunition through the barrel of the gun.
