I agree with Mike and aae. Messing around with my stuff, I feel the light laser combo is the best option and that the MOS is more of a hinderance than help. Specifically talk about home defense and assuming most encounters would happen at night with low light. IMHO, in a true home protection situation precise aiming through the irons or red dots is not always going to be a option. Might be shooting from a sitting, lying in bed, hiding behind a corning position and the option to just get the laser on target and shoot from the hip could be useful in a survival situation. So I removed the MOS from my main home defense weapon. Outdoor or CCW, different story.
