I have a matching pair of Shadow 2s for USPSA and a Target II for IDPA, all from CZ Custom. Grips, sights, and triggers are all as close as possible to identical. I can feel the difference in weight, which in turn, makes the guns balance differently. However, at my level (mid-C Class USPSA) it’s insignificant. I really enjoy shooting all of them, but practically speaking, I’d have been best off with a pair of Target IIs for my purposes.
