When I turned 21, one of the first things I did after my college classes were over was purchase a Hi-Power. This was before NICS, and after the brady law, so I had to wait 5 days. It was a LONG 5 days. It looks like you've thought it out well, and if you go with the Beretta, I have no doubt that you will be happy. I'd still like to get my plug in for the Browning HP. If you're comfortable carrying "cocked and locked", it gives a nice, consistent trigger pull. My BHP is wickedly accurate without having any work done. Hi-cap mags are available from several sources. It's got the classic lines, and I believe a little more character than a 92F. But make your choice and shoot 'till your heart's content. For a first gun, I'd definitely lean towards a 9mm. As a college student, I appreciated the fact that I could get more bang for my buck with a 9mm. Good luck!
