I know, I know: 12 gauge is the best for dropping thugs. But I just do not like the kick of it all. So, can you fine folks steer me toward the best choice in a 20 gauge to be used for outdoor range practice and, God forbid, a home defense situation? Price is not much of a concern. Reliability is key. Availability of accessories is semi-important. I don't have a preference as to pump or semi-auto. Thanks a lot!
