Mine was the same as yours out of the box. It did shoot left about 2" and it wasn't me. Front sight was centered per my dial calipers but the rear was off slightly to the left. To fix it, I clamped the slide in a vise with rubber jaws. I took the largest punch that would fit in the dovetail and ground one side of the punch flat to give as much contact area on the sights as possible. I then covered the tip of the punch with a couple layers of electrical tape. Mark the original location of the rear sight with a pencil so you can easy see when it moves. Loosen the set screw and using a large ball peen hammer and hit the punch. Start out with light hits and work your way up until you see the sights move. Once you have the sight where you want it tighten the set screw, wipe off the pencil mark with some gun oil, reassemble the gun and go test it out. Once I verified my was dialed in I removed the set screw and added a drop of blue Loctite.
Some folks say this can't or shouldn't be done. I had no problem moving the sight this way although it did take a few pretty good whacks to move it.
My wife's Shield shot consistently to the right and her front sight was off center to the left. Using the same procedure I moved her front sight. Not saying this is the only way to do it but this method worked for me.
