Pistol Grip Shotguns
"I have to ask, why the bias against pistol grip only shotguns? For a home defense only weapon, an 18" barrel with a pistol grip and a laser sight seems like the perfect shotgun setup."It's a personal thing. I prefer to aim my guns by looking down a barrel at sights or beads. I'm more accurate that way. A defensive weapon is only useful if it can stop a threat. If you can't hit what you need to, the threat is not stopped. In a home defense situation, you definitely want to hit what you intend to. You do not want to kill family members in the process with stray shots.
If you want a pistol grip only shotgun with a laser sight, buy one. If you can consistently hit what you want with it at the distance you need to, then keep it. If you can't effectively and reliably stop a threat with it, then look at the gun objectively and decide whether you want something that you can use more effectively.
I couldn't hit squat consistently with a pistol grip shotgun fired from the hip. They are great fun though.
