That kind of match sounds like a lot of fun, might have to see if I can get one set up here. Personally, I would probably use one of my Model 60's. The one with the holosight just might be the ticket. Then I would take a screwdriver, gouge up the stock, sand through the finish in a few places, wrap some duct tape around a few places, and smear some paint here and there. Nothing to affect accuracy, but just make it look like a total piece of crap. Then go out and whoop up on the guys with the customs and the high dollar rigs. Or get my butt kicked. With the friends I shoot with, either way we have a good time.
