I'd delete Taurus from consideration. IMHO. The Browning Hi Power is a favorite of mine, the 9mm caliber is cheaper than 45acp, so rather than a 1911 I'd look to that. Condition is paramount, so if it is a semi-auto look at the innards for visible wear. I prefer double action only semis and revolvers, so if you go revolver a hammerless DAO J-frame would be my choice. S&W airweight 38spl or the more expensive 357s. Kahr Arms or Glock semi autos are also my preference for CCW.
