Not quite. Glocks are technically still DAO, though not in the traditional sense. When you rack the slide on a Glock, it is in essence only 'half-cocked'. When you pull the trigger, the striker spring moves rearward (one action), the safety's drop, and then the striker drops (second action).
Again, I say it is not traditional in the sense that if you have a miss-fire, there is no second-strike capabilities.
Most other striker fired guns simply drop the striker when the trigger is pulled (single action).
Cliffs: Glocks are weird. Semantics and all that.
