A tie between:
Timberwolf .357 pump. Yowza, what a beautiful little carbine. I bought it second-hand but in "indistinguishable from new, probably never fired" condition from a guy who bought it as an investment and kept it in a safe for the better part of two decades. Nicest wood I have EVER seen on a rifle, except maybe an exotic at a gun show.
Marlin 1894 SS .44 magnum. First rifle I ever bought and a real "take care of business" machine. Solid, reliable, a gun I have 100% confidence in.
Like someone else mentioned, I do "like" my handguns, but they just don't grab me at the same emotional level as these handy little carbines.
