You're right, rufus. I couldn't quite tell, to be honest. The reason for the tests, however, was to find a replacement for the 9mm, and the 5.7 and 4.6 were candidates. After the testing, the 5.7 won - and since they decided to go with it, I'd assume that means it was better in their testing than the 9mm. I'd like to know more and see how those tests went down.
