If I can go afield, my first choice is a .357 Magnum.
Smith & Wesson Model 686+ 4" barrel
Ruger Security Six 4" barrel (in Colorado - because I leave one up there and if my friends move to the Southeast then it will be there with them).
If I happen to actually plan a field trip where really big animals abide I would switch to a .45 Colt. For my taste, a 44 Magnum is a waste of energy unless it is downloaded to .44 Special. I can get three rounds or more down range, accurately, with a .357 or a .45 before anyone except a super professional can do it with a .44 Magnum.
Smith & Wesson Model 25 4" barrel
I don't mind carrying a blued gun in the field. If it gets messy I can clean it.
