No. The .40 S&W is what they switched to because the wussies couldn't handle the 10MM. The .40 is the same diameter round, but in a case about the same length as a 9mm. No where near the ballistics of its big brother.

Yer talking a .40 with a 180gr at 900fps vs a 10mm 200gr at 1200 fps. No comparisson what so ever.

True, but you're only talking about one .40mm load. There are some much faster loads, 155gr @ 1200+ FPS, 135gr @ 1325 FPS, (See this article) which perform quite well. The full-on 10MM loads are certainly monsters, but if the FBI doesn't like the recoil and muzzle flip they give, its enough to make me think twice. Besides, the .357 JHP at fast speeds is the reigning king. Fast .40 S&W loads are pretty comparable.

Ballistically, the .40S&W is almost identical to the 'tried-and-true' .38-40, which was never considered to be an espescially 'wussy' round. Unless you're wanting to put meat in the freezer (which even the .38-40 did for decades), how much power do you need? You planning to shoot through steel plate, or what?
