If Colt was represented at all in the trials it was with a prototype weapon similar to the Double Eagle that never went over but that was Colts first try at developing a DA/Sa weapon .
XM9 Pistol Trials of 1984:
Guns tested:
1. Beretta 92 SB-F
2. Colt SSP (a ss double action pistol that combined elements of the 1911 and SIG P210)
3. FN Double Action Hi Power
4. H&K P7 M13
5. Sig P226
6. S&W 459
7. Steyer GB
8. Walther P88 (version prior to the civilian version)
US Army requirements:
Double action - defined as the "ability of the shooter to get a second strike on a malfunctioning primer without having to use his support hand to recock the hammer or reset the slide" Capacity of at least 10 rounds (15 Preferred).
By this definition the Glock was not technically acceptable.
1911A1's were used as control weapons in the test and the 9mm's had to equal or surpass the 1911's performance.
First phase at Ft. Dix NJ - Firing pin energy test and reliability and endurance test (3 pistols had to fire 7000 rounds and outperform the 1911 and if one pistol failed all failed). Beretta, Sig and S&W all outperformed the 1911A1 which had a reliability rate of 99.30%. This test also caused the first casuality of the tests the Steyer GB failed to equal the 1911A1 control guns and was eleminated. S&W failed the firing pin test and one of its pistols failed the endurance test but it was not elimated at this point.
At this point two guns were voluntarily withdrawn from the competition were the FN Double Hi Power on May 31 and the Colt SSP on July 18. Colt decided it didn't want to tool up to make the guns to the government's timetable.
Second phase- accuracy and human factors and various adverse condition and harsh environment tests- including Salt Water emersion, Wet and Dry Mud test. The Walther P88 failed both mud tests, no gun tested bested the 1911A1 control guns in this test. the 1911 was 100% in the mud tests while the HK was 99.5 % Beretta= 97%, SW= 97%, Sig = 88%. The Sig was particually awful in the dry mud test. But again only the Walther was elimnated.
The Salt Water test claimed the HK P7 M13 which failed to best the 1911A1 control pistol. The 1911 = 99%, Beretta and Sig = 100%, SW= 97%, HK= 86%
SW was finally eleminated for failing the service and firing pin.
Leaving only the Beretta and the Sig left to bid on the contract.
The bidding is another story for conspiracy buffs.
Whew..... FWIW
