100 yards, hmm... farthest I’ve ever shot my S&W 5906 is 67 feet... still hit COM at that point though...
.22 Ruger Mark II at 300 yards.
.45 Colt Combat Commander at 225 yards.
A whole bunch of handguns in various calibers at 65-75 yards at claybirds sitting on a dirt bank.
With a 6 1/2” .357, I could, with intense concentration and a bench rest, get it down to 10”.
Pistol shooting at long range is fun and educational, but it sure makes you appreciate a rifle!
Learning some of the better ways to shoot prone(rollover prone) and from a rest are worth while for long range shooting.
it would take a .22 and a heck of a lot of practice to hit a human at 100. I would do ok at 25 yards maybe 50 if the terrorist stands still.
