If your right handed Armaliter..it looks to me like you are putting side pressure on the grip with your right finger tips.
Try holding the gun in your strong hand with just enough pressure to keep it from falling out of your hand. Then form a C with your weak hand and place it over your right hand with your fingers over the fingers of your right hand, thumb on the web of your right hand between your index finger and thumb. If you will get bit by the slide then place your left thumb over, below or beside your right thumb.
Now squeeze straight back with your left fingers keeping your right fingers relaxed and your left fingers as straight as possible. You should be able to slide a pencil up between the palm of your strong hand and the grip of your gun.
you will need someone else to slide the pencil up!!DOH!!When I shoot I force the finger tips of my strong hand into the palm of my weak hand to ensure they aren't putting side pressure on the grip.
Another thing that suffers when you clench up your strong hand is trigger control. Make a fist and squeeze as tight as you can. Now move your trigger finger like you are touching off a round. Now relax your hand and try again. Quite a difference isn't there.
[edited to add] from the look of the flyers..your looking at the target instead of your front site.
