The best 9mm? Whoa... Um, there's like 8,537 different 9mm handgun manufacturers.

Anyway, IMHO, the most solid, wickedly accurate 9mm, is made by CZ. It's the CZ-75B full size version, on par with Beretta 92FS and the various S&W 9mm's. The thing is, people might look at it like "CZ?" and then think "Oh yeah... That's that Czech Republic/European police handgun". The CZ models are built like a tank and will feed any type of 9mm ammo without any issues at all.
