I just bought a new Mossberg 500 with the wood finish and hunting barrel. I have a few questions of ignorance as this is my first pump shotgun. I have my first single shot .20 ga and an old BP shotgun but have not owned a pump shotgun before. 1. What are ghost ring sights and do I need them? 2. Why does it have a gold trigger? 3. What mods would you do to it? I have asked Stalkingbear a few questions via PM. Thanks in advance.
