I have loved that gun. First automatic shotgun I ever owned. Real easy to clean and I clean the piston a lot. I drop it down in some simple green for a couple of days, put a little gun grease on the rails. I could always tell when it needed cleaned because it would start needing a little help closing the action. Now we soak the piston and put a little grease on the rails every year before duck season. That gun has been shot thousands of times. Would buy it over in a heartbeat and it's now my sons. Rick
