I'm probably more thorough than necessary by removing the cylinder when I clean. But I do. I get into all the nooks n crannies that revolvers are (in)famous for. I've got the procedure down cold and it takes about 40 minutes. It's a pain; but I want my guns to function as designed, and they have to be clean to do that. I've had wheel guns bind up on me during extended camping trips when I was putting lots of rounds through them without cleaning.
I learned it from my father: "You shoot a gun. You clean a gun."
