Alternate Front Sight?

Try changing the load. At short ranges a handgun will shoot lower with with a lighter bullet and higher with a heavier bullet. This seems contrary to the usual thinking in terms of bullet drop and a heavier bullet usually being slower, but at short range the dominant effect is "jump" that part of the recoil that takes place before the bullet leaves the barrel. The heavier bullet produces more jump so the muzzle is higher when it exits. Again at short range and with a given bullet the sighting will be relatively insensitive to the muzzle velocity so if you are handloading you can vary the velocity with a given bullet and not change the point of impact by much.
