andrew brought up a good point about matching ammo types.
here you go:
main would be a Ruger 10-22 CRR rifle http://www.survival-gear-guide.com/Ruger-10-22-CRR.html
sidearms would be either a taurus MODEL 94 .22 LR REVOLVER, or a walther P22

cheap, light ammo, low recoil, low report, low velocity ensures complete estruction of enemy zed's brain. easy to stockpile before apocalypse occurs due to the price of ammo and ease of storage.
