Just got done reading another article on the adoption of this 1911 by the FBI SWAT. First of all, there are two special units in the FBI, the SWAT and the HRT. Both fall under the same leadership from the way the article sounded. Because of compatibility reasons one sidearm was to be chosen for both units. The HRT had been using the Les Baer customized Para Ord P13. The SWAT was using SIG 226s I believe. The Paras were having reliability issues, most of which were addressed, but at what seemed like a great expense of replacement parts of nearly all the internals. An extensive test was conducted under guidelines set forth by the FBI for specifications of what they expected from the single stack .45s. Anyway, in the end, the Springfield Armory Custom Shop .45 won the contract. This pistol is one piece of work, believe me! After what they put these pistols through they have to be. I think the testing was about as extreme, if not more so, than what the ARMY put the M9 pistols through back in '85. They made a good choice too. Some of the others in the test were Wilson, Colt, Les Baer (I think), and a few others that I can't remember right now.
