i'm 6'6" 280. i can comfortably shoot the walther pps (or xds) with anything but the smallest mag. the smallest glocks are harder to hold onto for me. i can also easily handle the ruger sr9c.
if you can find one in good condition in your price range, the hk p7 psp is hard to beat.
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
