I have acquired a Remington 1900. Blue book lists the gun as either k or kd grade, with out ejectors or, ke and ked grade with ejectors and damascus barrels. Some how I was under the understanding that damascus barrels had swirl marks in the finish and were more fragile the others. I can not find a grade, but I do have the ejectors, so I guess I have damascus barrels.(but don't have swirl marks) Is this good or bad?
