How does a Glock work?

Very well!

After putting a loaded magazine in the magazine well, you let the slide slam shut to push a round out of the magazine and into the chamber. At the same time the rear edge of the trigger bar ‘grabs’ the firing pin lug


and pulls the firing pin part of the way back to a ‘partially cocked’ position.
