The easiest way to remember which way to adjust your sights is the Acronyn SO. Think of it like "SO my sights need adjustment" S means the rear sight is drifted the same direction as where your "Missed Shot" hit. O means the front sight needs to be drifted the opposite direction of your missed shot. That will bring you in on target. Also if your sight feels a bit loose in the dovetail when you tap it over (brass hammer or piece of brass) knowck the sight out, take a sharp center punch and "lightly" make a 1/2 dozen little punch marks in your rifle or pistols dovetail. That will help tighten things up.
