I agree that the express model's finish would hold up fine if kept oiled/indoors. I like having a more stout finish since I like to take it outside for fun. I took it out to a private range the other day for the first time and it started pouring. It was nice to not have to worry about the water. Also, if the SHTF, I would saw the butt off and rock it like Denzel in the Book of Eli. In that case, it would be nice to have a high quality finish on it. I'd hate to have to shoot a zombie with a rusty gun. I supposed a good coat of cat oil could work though. Food for thought.
