What about Lugers or Walthers (Kurtz) and even Mausers-which were actually used in combat?
What about H&K?
The only S&W 9MM outside of police issuance I've seen are the stainless ones currently carried in Cambodia.
The only "combat" 9MM in your poll is the Browning HP, which has seen real combat. The Glocks, Berettas, Sigs, etc. have only seen limited action in Desert Storm, the Falklands, Isreal/Lebanon and the Balkans.
The best gun (or 9mm) is the one in your hand when you need it.
