Many of shooters have wondered “why are my shots low and to the left?” Well wonder no more. The root cause of such a problem is caused by improper placement of the index finger on the trigger. The correct placement of the finger would be the middle of the top section of your index finger. Try to get it as close to the middle as you can just like this military training photo.
By pulling the trigger with nearly the end of the finger, you make the trigger go straight back. Using more of the finger will push the whole gun off to the side, thus making your shots not as accurate as they could be.
Do this and your groups will improve. Try this tip the next time you come into the gun range at H&H Shooting Sports. https://www.hhshootingsports.com/shop/ranges/
