The .40 S&W in particular, as well as the 9x19 (at least with current generation, premium JHPs), the 357 SIG and the .45 ACP does have record of being effective in a LE/anti-personnel role--something that noticably lacking in the case of the 10mm.
Again, that is correct, but not for the reason that is implied. The 10mm has no impressive record of LE/anti-personnel performance because it has never been particularly popular, not because of any inherent deficiency in the round.
Furthermore, if you're going to agree that the service pistol class calibers are for all practical purposes identical in performance AND then also try to imply in the next sentence that the performance of the 10mm is inferior, then I have to second warriorsociologist's comments about disgreement for its own sake.
Here's the best history of the FBI issue firearms I could find. It doesn't agree 100% with the other sources on the web, but it is far more comprehensive than anything else I found and it doesn't seem to be contradicted directly by anything that looks credible.
While the 1076 pistol was only issued for a period of less than 5 years (sources vary on the exact number with a range from 2 to 4 years), the FBI's "flirtation with the 10mm" round could not really be described as brief since it is still ongoing. The 10mm round is still standard issue to FBI SWAT and HRT teams in the H&K subgun.
