You just described why it won't work.  The hammer follows the slide down
and hits the firing pin with insufficient force to fire the next round.
For full auto fire, the hammer would have to be held back until the
slide fully closed.

I've had a Colt machine gun on me but it was because of a worn sear that
did just exactly what I described.  The sear would hold the hammer
back until the slide slammed home.  The vibration would trip the sear
and BANG.

I can assure you it gets your attention when you're not expecting it.
Seven rounds go REALLY fast.
