Some excellent suggestions so far. And they run the range in price, as well. I agree it would be hard to go wrong with the CZ or the Browning. I also think you might want to look into the 3rd generation S&Ws a bit more. Some are already heirlooms, such as the CS9, if you can find one. The 3913 is another excellent choice.
There are also some great 1911 9s out there you might look into. Check out the Kahr P9, too.
