The magazine follower, the plate at the bottom of the magazine that you push down when you load the bullets, will push up on a spring loaded catch mechanism after the last round is fed into the chamber. When the slide comes back after firing the last round, it is caught by the now raised catch mechanism, called the slide catch, and held open.
The slide should only lock back when you have an empty mag in the well or when you lock it back manually by holding the slide catch release to lock the slide. If it stays open after you rack the slide back to load a round in the chamber there is a problem with the gun.
"The whole of the Bill (of Rights) is a declaration of the right of the people at large or considered as individuals.... It establishes some rights of the individual as unalienable and which consequently, no majority has a right to deprive them of." (Albert Gallatin of the New York Historical Society, October 7, 1789)
"A free people ought not only to be armed and disciplined, but they should have sufficient arms and ammunition to maintain a status of independence from any who might attempt to abuse them, which would include their own government." - George Washington
