STICK WITH YOUR 870!!!! I have your exact gun and have never had any problems with power. I know someone who also has a 12 gauge 870, and he has had his for about 10 years and also dosen't think 12 g, is too small. In my opinion getting into the most powerful kinds of guns just gets u skybusting more. People who think 12 gauges are too small for geese are probably those people you see shootin at geese as soon as they can tell wat they are!![:@]
