I own a M21 20 ga O/U. They are pretty to look at but nothing special to shoot. They are not a high volume gun. I shoot about 7,500 rounds a year at skeet and of that number my CSMC shotgun accounts for maybe 150 rounds. Everything else is shot with my Brownings. My 725 20 ga Sporting is a much better shotgun and a much, much, better value. I do like to take it out and look at it once in a while. Mine hasn't given me any problems, it's just like a blonde super-model, nice to look at but not much of substance there.
