多谢版大的指点，狂补了firing pin block的课。拆开XDE研究，发现它和下面描述的SIG是一样的原理：
The safety system is inside the slide in the form of a firing pin lock; if you took a pen and tried to press forward the firing pin, with the hammer cocked, you wouldn't be able to move it far enough forward to touch the primer - the lock is 'engaged'.
When one squeezes the trigger, a disconnector lever rotates up alongside the sear and pushes the firing pin lock upward, against its spring, and disengages it from the pin - thus it will now be free to move fully forward. If you take the pistol apart and look at the frame, as you squeeze the trigger you will see the disconnector appear just before the sear releases the hammer.
If you don't take the shot, then the firing pin lock spring re-asserts itself and re=engages the lock as you release the trigger.
简单的说，只有扳机被拉到激发的位置点才能释放firing pin block，撞针才能被移动。否则，无论是枪口还是枪尾落地，撞针都被锁在slide里，无法移动接触到子弹。对XDE做carry用枪感觉信心更足了。

确实如你所说，half cock和惯性firing pin都有，只是我原来都忽略了，以为所有的hammer枪都这样
