Not to add to your dilemma...but own the H&K USP compact in .40S&W with LE trigger and tritium sights.
Great feel, nice accuracy and the most reliable pistol I have ever owned...about 5,000 rounds through it, never had a jam or feed issue...love the reliability, love the engineering, love the feel.
I prefer the .40 round to the 9mm - bigger, heavier bullet with much greater energy, closer to the .357 magnum for stopping power. The 9mm is great for carrying lots of rounds, but the .40 allows you to double stack too, and you get the better ballistics...
H&K is not a cheap option, mind you...
