I know lots of people who did it perfect their first try if they are familiar with working with jigs and drill press. A understand p320 fire control group is nearly impossible to screw up.
Also in places where it is legal to make them, while you can't have someone make it for you and sell it or gift finished one to you; there is as I recall some latitude as to advising you while you do it. Exactly how much advice while you do it I don't recall, but there is some amount of advisement that is allowed.
You are wrong. Only 3% of 80% kits can ever be finished and that's just a theoretical %. I'm pretty sure the actual number is 0% as all malfunction and are thrown away.
