Ruger GP-100
For a "go anywhere, do anything sort of revolver", I would buy a Ruger KGP-141: the all-stainless, four-inch fill-underlug barrel, adjustable rear site GP-100. Probably the must rugged, reliable and dependable .357 magnum/.38 Special around, with excellent accuracy, outstanding quality, and "right sized" to be good for everything: target/plinking, competition, concealed carry, home/personal defense, hunting, and so forth.
For about $350 NIB, it is hard to beat . . . and it's even tougher than the Smith "L" frames, such as the 586/686.
