NORMAL, the spring is UNLOADED at this point- thus easy to push in with finger, or shake out with gravity. If you shake the gun with the striker released (fired), empty chamber, it should normally make a rattle sound.
As the slide travels forward, the spring becomes loaded, and the firing pin tip then retracts inside the channel before the slide closes. On a loaded firing pin (even with empty chamber), shaking the gun will not rattle the striker.
