Thanks for all the input. Based on the feedback, and other research I've done on the web, I'm planning to go with the Springfield Armory XD.
I'm pretty old school, and I've always had a soft spot in my heart for the classic Beretta/Taurus lines and the feel of a metal frame gun. That said, there are times when you just have to "step into the future," and this may be one of those times.
There's a gun show this weekend, and if I come across one of these at the right price, I may just have to pick one up.
Of course, there remains the age-old question: WHICH CALIBER? I'm leaning toward .40 S&W, but I'm open to being persuaded otherwise.
