When I shoot pistols I nearly always hit to the high left. Any suggestions other than aim right?
I am left eye dominant and shoot with my right hand. I've seen the target that shows what one is doing wrong but that aint it. Both eyes open  or either eye closed. Using my left hand I also hit to the left. Maybe I shoud get adjustable sights ?
I shoot rifles ok with my right eye scoped or not.

what happens when you shoot the pistol off a rest? The easy fix is just to get some adj sights

never tried it off a rest. how much is a pistol rest ?

The way I sight in a pistol;

Go to a shooting spot, not a range unless they allow you to sit, and sit down with your knees up and your arms resting on them. It's easier if you have the back of a truck or something to lean on. Then just take slow aimed shots. Do it at close range first and then work your way out.

If you can't do that, have a buddy shoot it to find out if it shoots the same for him.
