Without breaking the bank too bad, here are the choices:
1) EAA IZH-46M - These are 10M match guns and are more accurate than you can hold. Price will be in the $300-$350 range for one but it is worth the money. I have one and it is one of the 3 airguns that stay no matter what.
2) Daisy Avanti 747 - These are good pistols for about half the price of the one above. Good accuracy.
There are others but these 2 are ones that are listed as good to excellent for your purposes. Remember that these are target guns and not hunting guns - FPS won't be more than 500 on the IZH and less on the Dasiy.
