i voted for the xds just to give your poll some meaning. of the ones you listed, the xds is definitely the way to go. personally though, i like to carry 9mm, so i carry a walther pps when i want something as small and concealable as the xds, and it's big brother the ppq when i have a sweatshirt on.
Favorite range gun for the money - CZ 75B or STI Spartan V 9mm
Go-to carry setup - Walther PPS or PPQ in FIST kydex holster 1AK
Favorite semi-auto design - HK P7
