There is so much that could make or break a deal, even on a cheap sxs. I mean what good is it if not safe to shoot. Also depends on what an individual is willing to overlook. Starting with cosmetics. What shape is the stock and forend in. Are there any cracks in the wrist area or else where. How worn is the checkering, if any. Has it been shortened. How much bluing is left or how badly is it rusted or pitted. Has it been professionally reblued. Are there any dents or bulges in the barrels and is the rib still tight. Do the barrels ring when tested. What are the bores like. Are they rusted or pitted? How about the receiver. Any burn marks into the face around the firing pins. How tight is the action open or closed. If it is worn much then you are into a few dollars to correct assuming the gun is worth it. Have the chambers been lengthened. Is it single or double trigger and do both barrels fire. Do the ejectors work if so equipped. Is the opening lever off centre. Have the chokes been opened up. As I said, there is a lot to look for. Some problems can be overlooked and still be safe to shoot but other problems are not. If it is a fairly low cost sxs, then many times they aren't worth the repair. Also, the older guns were not designed for steel shot.
