You can drift the front sight or adjust your rear sight. If you feel uncomfortable doing this(drifting front sight) I'd take it to a gunsmith. You can obtain a sight tool, drift it yourself w/ a wooden dowel and a hammer or, I just drift my sights with the small extension in my socket tool set and a hammer , or punch(may leave a little mark). I do prefer having the front sight center and adjusting the rear sight for windage. Lastly, I do recommend benching the pistol for groups when checking zero. I assume your front sight is off center to the right.
