I keep a Supernova next to my bed should an unwelcome visitor find themselves in my home. It has the 18.5" barrel, pistol grip stock, ghost ring sights and I added a nordic components magazine extension tube.
I keep the magazine tube loaded with Federal 00 buckshot or Brenneke HD slugs. Outside of HD, I've been really impressed with all of the various Brenneke slugs. If I can ever find some Federal #1 buckshot that will replace the 00. Seems hard to come by though as I believe they stopped manufacturing it.
I keep the Supernova's safety off. I figure the first warning to an intruder is the locked windows and doors. The second warning is the sound of the Supernova being pumped. If that isn't enough to deter an intruder, I'm going to assume they are dangerous and intend to harm myself or my family. Hopefully I'll never have get to the point of having to decide to fire on someone, but should I find myself in that situation I plan to be trained and prepared well enough to handle it.
Better to be judged by 12 than carried by 6...
