While the longest on-duty rifle shot fired by police, of which I'm aware, was against an active rifle shooter at something like not quite 150yds (it took 2 shots for get the hit that stopped the threat, as the first shot missed), and the longest handgun shot was 104yds (in TX), I have a hard time imagining me, as a retired cop/private citizen, ever finding myself in a situation where I'd be using a rifle or handgun out to those distances. I didn't have to do it in all my working years, and that was being put in innumerable situations where it was highly likely to happen on any given day/night.
The only times I've even prepped my personal AR was when some serious potential threats appeared to have the potential to approach our previous property and our new one. One time involved a suspect thought armed with a semi or full-auto carbine and wearing body armor, who had fled from a nasty shootout with a local tac team at a raid on a grow property. The best update I got was the suspect was thought to be on foot, maybe a mile or so away, heading in our direction in a semi-rural hill area. The possibility of body armor meant AR (to me).
The other time was when that active shooter who killed a Santa Cruz Co SO sergeant was initially reported to possibly be headed our way (our property isn't very far away) in some of the evolving news reports. (Meaning social media activity, with some of my wife's friends learning of the active shooter on their news feeds and calling my wife, scaring her). My wife was (uncharacteristically) very concerned, so I prepped my AR and one of my shotguns, to ease her concern about the suspect reaching and coming down our street, and actually approaching our house.
Aside from extraordinary events, since I'm not looking to find, chase and apprehend suspects anymore, they're going to have to come find me. I can't imagine any reason why the same firearms training and drills covering 1-25yds, and occasional instructor training out to 50yds, wouldn't continue to serve me in good stead. I'd consider the potential for engaging anyone out past 15-25yds to be downright improbable, especially considering I'm no longer able to invoke peace officer powers and have an agency behind me. I worry more about the 1-10yd situations where I'm too close to get away or under cover.
Just my thoughts.
