OK Which eye does the winking. Shooting eye or the other one? Which is your dominant eye? The one looking down the barrel should be the dominant eye.

If you shift your focus to the sight from the target you will miss.

You should be able to focus on the target, bring your gun to your shoulder and shoot and hit the target without looking at the sights.

If your cheek hurts, the gun doesn't fit.

Sounds like you are "Crawling" the stock as if you are shooting a rifle.

To be sure the barrel is in proper alignment, try one of those light pipe type sights. They can only be seen if the dominant eye is properly aligned with the barrel.
