I was sighting in a gun the other day and after I'd finished, my wife asked a question that made me stop and rethink the process I'd just spent over an hour completing. I was sighting in a SBR (I have the class III stamp so it's legal) I'd recently built and my wife suggested that the gun could be put to good use as a home defense weapon. I said it sounded like a good plan to me and since I have several different sights on the gun (red dot, laser and iron sights), I began the task of coordinating and adjusting the various sights on the gun so the points of impact would be the same at the same distance, 50 yards in this case. FYI, that's about the maximum distance I can shoot in my yard directly before encountering a fence or building. After I was finished, my wife asked what I'd been doing and then said 50 yards was a long way to shoot at something if this gun was intended as a HOME defense gun vs. a PROPERTY defense weapon. She then asked where to aim the gun if a BG was already in our house since it was sighted in for 150 feet, not 15. I told her at 15 feet, just point at the COM and pull the trigger. Anyway, she got me thinking and I'm considering a change in how I zeroed in my sights. I'd leave the laser zeroed at 50 yards, but change the red dot to impact POA at 50 feet (the max direct line of sight in my house). The adjustment change on the fixed sight is so close at either point that any change would be negligible. My thought is the laser could be used outside while the red dot would be used inside the house. My iron sights would still be there as a back-up or alternative to the optics. Any thoughts would be appreciated on whether I'm making something out of nothing and it's not worth the trouble, or is having sights zeroed for different distances a good way to go? FWIW, this is not an optics vs. iron sights thread but rather is it a good idea to have various sights (if they're available) have a POA/POI set at different distances to better your chances of hitting what you're aiming at? BTW, this is the SBR I mentioned.
