Hands down, my favorite is the High Standard Sentinel. Have one that belonged to my Grandfather, passed down to my Father and now it sits in my safe. Don't shoot it very often though.
For plinking at the range, the Walther P22. Great little shooter, never a hiccup with it. Also, I sometimes carry it as a backup. 10+1 of CCI Stinger's it's better than using harsh words or throwing rocks as a backup plan.
