Here’s a trip down memory lane for some of you. A rampage shooter attacking a courthouse was stopped by an officer who fired a single .40 JHP (one handed as the other was holding the reins of the officer’s horse) from over 100yds (as reported here... I’ve heard it was actually 80yds). Officer not indicted or arrested.

Apparently, people can not only hit targets with a handgun at that distance, they can do it when the chips are down. I’d guess that officer had probably practiced a bit at distance though and didn’t just start winging rounds downrange and hoping for the best.
