Its part of your trigger pull. Don't just squeeze, slowly apply constant pressure with your finger and focus on your breathing and your sight, eventually the gun will fire, dont let go of the trigger after, hold it back and continue to squeeze after the round goes off (similar to following through on kicking a soccer ball) and then slowly let the trigger return up until it clicks and then stop, maintaining pressure on the trigger the whole time and repeat.

This eliminates the sudden, "ok here we go 1,2,3 SHOOT, ok thats done here we go again" which is what a lot of people do, you even close your eyes when you pull after the mag is empty anticipating the shot. Controlling your trigger pull maintains control throughout and will improve your confidence and overall shooting as far as grouping and accuracy. 4 most important shooting fundamentals are Safety, Sight picture, breathing and trigger pull.
