As was previously stated, the 1911 was retired NOT because it was deficient in any respect, but because of a political decision.
The design is robust, far more so than SIG or Beretta, and the grip eliminates problems with having a variety of hand sizes. The round it fires is proven, and far and away better than 9mm ball.
The need for a high capacity pistol is a moot point. There is no situation that any soldier that carries a pistol will face where 3 mags and a 1911 won't cure, but 3 mags and a beretta will. People who feel otherwise should simply carry an extra mag.
