pps and p7 beat all, but the p7 can get pricey. the pps is very reasonable when you can find them ($500-600). the kahrs are ok too. if you are really looking to save money, look at the pf-9 i'm selling in the link below. i would NEVER go with a stock pf-9, but mine is upgraded.
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
