.30 vs 9mm?

To Tom C. et al, I do have new Fiocci 30 Luger AND 30 Mauser ammo available @$25 post paid per box of 50 rounds. $20 per box for 3 or more boxes. I'm surprised that no one in this sequence mentioned that 30 Luger has a flatter trajectory (less drop being a lighter bullet) and less recoil than 9mm, so is perfered by many bullseye shooters. But how accurate can you be with the standard fixed sights on a luger? Tom h
