Walther, Ruger and SIG all make small .22 pistols that would work for you.
I would avoid the single action target pistols like the large Ruger and Browning for what you're trying to do.
The Walther PPK/S in .22 would be perfect, but DAMN they're expensive. $600 at Gander Mountain.
OTOH, it would be a lifetime investment, and it holds it's resale value extremely well.
And I looked, and behold a pale horse: and his name that sat on him was Death, and Hell followed with him. And power was given unto them over the fourth part of the earth, to kill with sword, and with hunger, and with death, and with the beasts of the earth.
