Single-action and double-action refer to how a gun's mechanism operates when the trigger is pulled. The "double" in double-action means the trigger performs two functions: cocking, and then firing the gun. The hammer cannot be manually cocked back; only the pull of the trigger can cause that to happen.

What does double action Glock mean?

A glock is both "pre-cocked", and a double action. The striker is pulled just slightly rearward under the tension of its own spring when the slide is allowed to go forward. However, when you pull the trigger you add an additional "cocking", if you will, to the striker. This is what makes it double action.
