Wil Terry is correct, moving your rear sight to the right moves the impact point to the right. Just be careful you don't do as I did. I had the exact same problem with my new Bersa 380. I must have moved my rear sight too far to the right, however, as the screw holding in the rear sight fell out while I was shooting at my home range. Unfortunately, I didn't realize it was gone until I cleaned the pistol. The gunsmith where I purchased the Bersa said he was ordering several of the screws just for that reason. I suppose I should put some locktite on the screw threads when the screw comes in and I'm convinced I have the sight alignment set up properly.
