Outstanding!
If I were going after a .40 S&W, that's the one I would have gotten, too. I carry a G19, which is the same size, and I think it's the best package Glock has put together.
If I recall correctly, there was an article in Handguns magazine several months ago about "one-shot stoppers". Okay, now that everyone has rolled their eyes, let me finish. According to his review of the data, the 155-gr JHP was number one on the list. The 165-gr JHP was third or fourth. Personally, I've always liked a heavier bullet at a little slower speed than the lightest, fastest thing I could find. I'd probably go with the 165-gr, unless I could find a 180-gr +P load.
Any way you slice it, you done good! Now go practice!
