Setting aside the questions of profit for their makers and savings for their buyers, comparing the P210 to the P220 makes sense only when both guns are in the same state of tune. In other words, compare a service gun to a service gun and a match gun to a match gun. In comparisons of this sort, the P210-based gun will shoot tighter groups at 50 meters than the P220-based gun will at 25 meters. Anyone who doubts this claim would be well advised to read up on the subject, beginning with the factory design specs, certified test targets, and 50 meter service handgun competition results.
