I just have Mrs Sport45 run around downrange with a cardboard cutout of a bad guy held behind her. She gets really upset if I hit her instead of the target.
Just kidding, of course. I haven't graduated to tactical drills at the range. I just try to see how fast I can keep 3 to 5 rounds on a paper plate at 15 yards. I've watched IDPA matches and think that would be good training. Being a competition would add the adrenalin factor. Kind of like a HP rifle match.
