What is the primary function of the magazine in a semi-automatic firearm?

The primary function of the magazine in a semi-automatic firearm is to store and feed rounds into the chamber. The magazine holds multiple rounds of ammunition and, as the firearm is cycled through its operating process (trigger pull, recoil, etc.), it automatically moves the next round into position when the chamber is cleared after firing. This mechanism allows for faster follow-up shots compared to manual firearms that require each round to be loaded individually.

In a semi-automatic system, once a round is fired, gas pressure or recoil is utilized to eject the spent cartridge and chamber the next round from the magazine seamlessly. This allows the shooter to maintain a rapid rate of fire without needing to stop and manually reload with each shot. Therefore, the magazine is a crucial component that facilitates the automatic feeding of ammunition, directly contributing to the operation and efficiency of the firearm.
