I think for all handguns, the extreme effective combat distance is spitting distance.

Yes, at the range, with no pressure, no moving target, you can hit things way out there. But it is an artificial environment.

I recall reading about an attempt to make a Civil War Combat course "realistic". Re enactors would come up in squads and have to hit all targets before going on to the next stage. Of course, fastest time wins.

I read that one event, the match directors had set up a tennis ball “cannon”. Squads had to shoot while under attack from compressed air artillery fire. Apparently even the threat of being beaned with a tennis ball was enough to dramatically increase the time it took to clear all targets.
