I second the Kahr CW9. It would be a good range gun and concealed carry weapon.
My wife has a Bersa Thunder .380 as her primary. It is a joy to shoot but .380 ammo isn't as powerful as 9mm. I carry a S&W Bodyguard 380 as my pocket gun/backup gun. The .380 round is basically a short 9mm but ammo costs a lot more per box. 9mm ammo is the cheapest to shoot at the range except for .22 which is dirt cheap but isn't a defensive round at all. If the only purpose is range gun get a .22 not a .380.
Therefore the Kahr CW9 wins in my book that meets your criteria and within your budget.
