Where are the groups at 7 yards? How large is the group? How the the firearm shoot for someone else?
The front sight being off a little is not bad if it groups consistently in or near the middle. If the sight is off to the left, then moving the sight to the center will move the point of impact to the left (the front sight is adjusted opposite the rear).
