I figure that the distance my pistol dot is zeroed at is of less importance than my ability to put the first shot in a 4" circle.
Thinking along those lines, it would make sense to me to zero it at the furthest distance I may encounter in a given situation. In our house, there isn't going to be anyplace where we would need to shoot beyond 25'. Nightstand pistols are zeroed at 25'.
Outside, I wouldn't expect a threat to be much beyond 30' by the time I have my weapon cleared to shoot. In our church sanctuary, a shot between 60'-75' could be required. Different tools for different jobs. Same required result, 4" circle.
Each scenario I list has a different gun prepared for it. They all have a redundant laser on them. I don't expect to get a second chance. I am using every option available to me to make the first shot the last one required to end the threat.
Regardless, unless I practice and train to reach that required end, no amount of equipment will overcome a self-imposed handicap. Just because the gun can doesn't guarantee I will.
