I had mentioned above that it could be that you need bifocals to see the front sight more clearly. I mentioned this only because this happened to be my problem. Clearly, from the posts, it is more than likely a trigger control problem (this is one of the reasons I burned through many more rounds and worked on trigger control like a beast until I convinced myself it could not be my trigger control). To test your trigger control, try this drill:
- Place a dime or penny on the front sight
- Dry fire
- The dime or penny, if squeezing the trigger correctly, should not fall off
- If it does fall off, carefully determine whether it falls forward, to the left, or right
This will let you know if you are dipping the gun (anticipation of recoil) or pushing the gun to the left (falls to the left), or pushing the gun to the right (falls to the right). You now know what to work on.
My range officers had an expression for squeezing the trigger... 1/4 lb, 1/4 lb, 1/4 lb, 1/4 lb, 1/4 lb, 1/4 lb, ..... BANG! You should never anticipate the gun going off, you should squeeze a small amount steadily until the gun goes bang.
Hope this helps too.
If you find the trigger control is not the issue, nor the grip, nor the sight alignment.... try your eye doctor like I previously mentioned. I thought I could see the front sight just fine, then when I went shooting with my new lenses, I was surprised how crisp the front sight image got.
