3.5" groups at 24 yards is not great. 3.5MOA mean radius at 24 yards, which is what the OP stated, is pretty a little better, but still not amazing.

3.5MOA mean radius at 24 yards would be groups that averaged about ~~1.8"~~ 2.6" or so the way groups are most commonly measured. Not amazing accuracy, but better than average. I would think that finding a semi-auto pistol that accurate wouldn't be horribly difficult.

To the OP: Is there some reason you are measuring your groups in mean radius instead of center-to-center of the two rounds farthest apart in your group? There's nothing wrong with mean radius measurement, but it's harder to do than the common method for group measurement, and since it is not commonly used in accuracy testing it will be difficult to compare the results you obtain to results you find elsewhere.
