Be aware that there is a screw in the front sight also... and a hole to keep the screw in place. The rear how should have some drift capability... however the front does not. Adjust the rear sight as much as possible within the hole... it was enough in mine to work things out. If not, you may need to look at adjustable sights.

To confirm, you are saying the hole in the slide is actually an "oval" with threading that fits a range of locations for the rear sight and screw...so I can drift the rear sight and (hopefully) the screw will still fit into the hole somewhere? If so, I'll give it a shot.

Yes... take a look when you remove the rear sight. The first time of remove the rear, it will be tight but a tap with a wood or brass punch will move it out... be sure the screw is raised above. Actually there is a good bit of play available.
