Re: AR vs Shottie for Home Defense
No, not an official instructor and not a complete dissertation on home defense with a shotgun. Arbiter, your point in regards to pattern was well stated and very kind and not insulting, unlike others, so I thank you. But as to light, little to no light poses problems which is key to my defense. BTW, I run a Surefire 618 LMG which has a great focused center beam which is also key to using a light for sighting. Expensive...yes, but I spend money on lights. I worked law enforcement for ten years with time on 3rd watch. Lights are a must to identify threats and even give you a change at using sights.
As to practice, I have practiced this repeatedly at distances of 10 yards and in and in which is what I assumed for most home scenarios. I will go and shoot my shotgun this weekend to confirm, but I am almost positive, at 10 yards, I had a 6 or 7 inch pattern and around 3.5 inch pattern at 7 yards with Fiocchi OO. Not a huge difference but better than just a .223 chance.
To improve my speed and chances to get at least some of those pellets on target, I use a light. My center beam is spot on with my point shooting, even at 10 yards, so no need to align sights when seconds count. Perfect..no, but I have a hard time finding sights even with the fore end lighting up the target. I made an assumption that people would consider their backdrop (bedrooms and such) before squeezing the trigger on a 12 gauge or any weapon in a house. Again, I have tried to align sites in the dark and point shoot with little to no light...in my opinion very difficult but other may be able. Best case scenario for me was just what I communicated.
I have practiced and I recommend the same for anybody who is worried about home defense. Don't just by a gun and light and lay it beside the bed. By the gun and light and shoot it in conditions as close to what you fear. Also, unload the gun and walk around the house and see if you feel agile enough to carry a long gun. If what I communicate makes sense and stands the test of reason, then try it. If not, practice with something and protect your families.
Blessings!!
