Mine came right one, but thats not to say yours may not be off. I'd fire the pistol off a rest for a couple of groups (even just beding over a sand bag) to double check that its not you. The sights are in a dovetail, there will be a small screw down through the top of the rear one. Loosen it off 2 or 3 turns, get a small brass punch and drift the rear (lightly) the direction you wish to move your group, tighten the screw and test fire. It's trial and error and you won't have to move it much. The only way to raise the group is to either file the front sight lower (so you raise the muzzle for the sight picture) or get another lower sight. If you call Springfield and tell them how low your shooting they will probably send you a new sight.
NOTE. If the rear sight becomes loose, it will shift around and sit low in the mount causing you to shoot either left or right and low. (my 1911 was bad for this, drove me nuts till I noticed the screw backing off)
