I've recently aquired a Winchester 1300 Ranger 20g that I was planning on using for home defense. It's primary use has been hunting doves durring season. It's got a 24" barrel that makes it hard to turn corners in my house if I needed to so I'd like to machine it down or get a shorter barrel. So, I've got two questions. Is it a dumb idea to have a 20g as a home defense gun? Is it possible to fit the tactical type of shotgun equipment (i.e. pistol grips, lights, folding stocks) for the 1300 12g model to the 20g? I know these may seem like dumb questions, but I've been looking all over for info on this and I've come to a dead end. Please help. Thanks.
