If you look through old Gun Digests, you will see a lot of customized Winchester Model 21s....and there's a reason for that. As expensive as they are for what they are, they still need a craftsman gunsmith with metal and stockworking skills to detail them into a game gun....with a game gun handling weight and feel. If you will spend the money, I know several members of the ACGG that have done and can do that kind of work. But you have to be willing to pay for what you want.
