There certainly are people in the world who could repeatedly and pretty reliably hit the target at 100+ yards. However they are not likely to be the shooters in that attack. The question stands: what common shooter can hit standing men twice with three rounds, from a handgun, at 120 yards? A typical ghetto shooter, who holds the weapon sideways, cannot hit the opponent from a few yards. It has to be someone with decent training, someone who went through a lot of rounds with this particular handgun.
P.S. I will try this feat at 100 yards next week if I can get to the range. Normally, it's a rifle distance for rimfire - for handguns people set their targets at 20-25 yards, if not closer.
I have shot deer at 200yrds with a hand gun. OK its a TC contender
25 yards is the max for any pretense of accuracy by me. At my age I can’t even see 120 yards.
NEVER make the mistake of underestimating an enemy.
