We also have to agree that "accuracy" is the size of the group, not the location. I've seen a lot of inquiries about getting adjustable sights for an "inaccurate" handgun, when the problem is the group printing out of the bull.
Accuracy should be linked to the expected target. I shoot at round, 8" targets, so any gun that can hit within 4" of the point of aim out to about 50 yards is accurate enough. If my target was only 4", then I'd have to either have a more accurate gun, or confine my shooting to 25 yards.
One rule of thumb for handgun shooting is, the target is in range when it appears to be the same width as the front sight. Even a gun that's only "minute of pie plate" accurate will suffice under those circumstances.
