If you can find such, I'd suggest a CZ 2075 RAMI in either 9mm or .40 S&W caliber. 6.5" long, 4.75" high, 7+1 capacity for the .40, 9+1 for the 9mm. Top quality, about $575, easy to carry. DA/SA action.
CZ* Ceskoslovenska-Zbrojovka (in Brno, Czechoslovakia)
CZ in Europe is like S&W or Colt in the U.S. Most police and many military units in Europe carry CZ weapons.
