Browning got the ergonomics, power, and shootability perfectly into one package. It is why so many firearms used the 1911 as a model. Classic SIGs are patterned after the 1911. While absolutely dependable, the shortcoming of the Glock for example has always been ergonomics. The fight always comes down to speed, power, and accuracy, and that formula will not change. With proper training and practice, the 1911 will give you all three. I think the 1911 will endure until human physiology fundamentally changes.
