I believe you are confusing several versions of the trials that occurred at different times.
There were 3 iterations of essentially the same trial, and another to follow later. I have the report somewhere, I'll see if I can dig it up, but here is the top of my head version.
The first JSSAP trials were administered by the Air Force in 78 or 79, and the 92 was declared the winner. The 1911 was used as a control here, though they were random 1911's selected from inventory, not new guns.
The second JSSAP trials were administered by the Army in 81 after they protested the results of the first. As mentioned in my earlier post, the weapons involved were the Beretta, HK P7M13, S&W 459, and the Sig P226, with the 1911 again as a control All 5 failed, the 1911 finished 4th, the Beretta finished 5th. The 459 did finish second in this trial as I recall.
The actual XM9 trials took place in 84. As mentioned previously, weapons involved were the Beretta, HK P7M13, Sig P226, S&W 459, Steyr GB, and the Walther P88. The only two weapons to pass overall were the Beretta and the Sig. The Smith 459 did pass certain phases, and was actually first in the accuracy trial. Sig came in as the low bidder, but Beretta was eventually awarded the contract on "official" basis of cost of magazines and replacement parts. Many have speculated that there were deeper politics at work.
After the XM9 trials, Smith alleged that the 459 failed only due to a mathematical error in awarded points, and after much investigation and political wrangling, the XM10 trials were scheduled for 1987. Beretta refused to submit any weapons for testing since they passed the XM9 trials, so stock Berettas were used. This test also included the Ruger P85. Beretta again passed. The Smith not only failed overall, but in fact failed portions of the trial it had passed in the XM9. Ruger failed overall as well.
I will see if I can find and scan the copy of the report I have, but the above is reasonably accurate to the best of my recollection.
The definition of an ejection port is an opening in the receiver of a firearm through which empty cases are ejected. The Sig has one, the Beretta 92 has one (it just happens to be huge), as do all semiautomatic handguns.
