Let me clarify one thing:

The barrel starts moving the same moment the bullet starts moving. So
it has moved a little before the bullet exits, but that movement is in
the horizontal, longitudinal axis. After approximately 1/4", when it
is sure that the bullet has exited the muzzle, the barrel is pulled
downwards by the link, unlocking the barrel from the slide.
