I've been shooting a long time so I don't believe it's shooter error. My shots hit about 3.5 inches to the left with my SR9C. How much do I need to drift the rear
Sight? I've never had to adjust a sight before.
First, do you have a solid bench rest? If you don't, then don't mess with it. Next, at what distance are you shooting? It's all about the angles. 3rd, do you have an adjustment tool or do you plan on using a punch and hammer? You can do it with a punch, but it's not recommended, since you can easily make the problem worse in the other direction or damage the slide or sight. Be gentle. I'd advise scribing a very fine line alongside the sight in the dovetail before you do anything, so you have a baseline to judge movement from.
As for how far to move the sight - not much. Move it only a tiny fraction (less than the thickness of a fine hair) at a time, take 3 shots, move it some more if needed, take 3 more shots, etc.
