Asking about a Remington 1100 Magnum. It's a 30" vent rib barrel with a full choke. The pictures make it look like it's in amazing shape and the owner says it's barely a scratch on it. Haven't seen it in person yet but would before buying it. Is there anything that should be checked with it before buying? Is there any reason not to buy one of these? What are the pro's and con's of them? The price is $450 for it. Is that a good price? What are these worth?
