It is an inertial firing pin, so it travels further forward
from a hammer strike than just pushing it flush with a finger.
From your description, it sounds a bit like during dry firing, the firing pin travels just far enough forward to allow the firing pin stop to slide downward, locking the firing pin forward. This theory is supported by the fact that someone tried to peen the slide to make it stay put...
Try dry firing the gun upside down and see if it still occurs.
