That's not entirely correct on the Glock. The difference between the action of the Glock and an XD is that the Glock's striker assembly is under little to no tension at rest. When the trigger is pressed, the trigger bar actually grabs the striker and moves it rearward against the striker spring while at the same time releasing the drop safety. As it comes to the rear of the cycle of the trigger the connector releases the trigger bar and the striker falls forward. On the XD, when the slide is cycled, it does actually load and cock the striker assembly so it is in essence a single action at that point. That is why the Glock trigger feels a little heavier than the XD trigger. The Glock is in essence cocking the striker when the trigger is pulled whereas the XD is not.
