The S&W 3rd gens have a real following. It sounds like several would meet your criteria perfectly. I have the CS9 which for a metal 9 is really light and small, but it only holds 7+1. A lot of the other Gen 3s have double stack mags with higher capacities.
I had the exact same criteria as you, but I wanted as small and light as possible.
Here is a great comparison chart:

Also, the S&W forum http://smith-wessonforum.com/forum.php is a helpful group of guys, and a lot of them are really into the Gen 3.
Good luck! Welcome to autos!
