Ejection and reloading

Now let’s see how the empty bullet case gets removed from the barrel and a new bullet takes place.

Because of the backwards movement of the slide, the bullet case also moves backward. Once the slide is completely at the end, there is an opening in the slide that corresponds with an opening in the frame just large enough for the case to be ejected. Because of the kinetic energy from the backwards movement of the case a little tap of a pin at the end of the barrel is enough to shoot the case out of the barrel. Now the case is gone it is no longer holding down the new bullets inside the magazine from going up. The magazine spring underneath the bullets constantly pushes the bullets upwards. It is the slide that returns to its starting position that pushes the new bullet inside the barrel.
