A number of good possibilities are out there, including ones that already have been mentioned thus far. Toss in the Walther PPS as still another consideration, in either 9mm or .40S&W. Just make sure that whatever you get, you try it, test it, shoot it, fire it, work with it, and then do it all again before you decide to make it your own ... and especially before you make it your primary carry gun, if that is what you have in mind.
