The auto pistol food groups: Colt, Browning, SIG, CZ, Walther, Glock, Beretta. There are other makes, like many from the "Colt 1911" group, etc. Pick just about any "proven" design from any of the makers above and you have a great "five". I'd like to have examples from each "food group", but practical limitations has caused me to have more of one than another. Five I'd like to have around me when I've shed the rest? Colt Government .45, Colt 1903 .32, Browning Hi Power, Beretta 71 .22, Walther P99.
