you look like you have two problems though .. the full hand push is an easy one to spot. trigger finger position and method is a little harder till your made aware of it.
seriously, get an airsoft gun to help you work this out.
Squeeze the trigger slow and easy like your father told you to and watch the front sight drift left as you do. I bet it does.
try slipping a little more finger over the trigger and see what happens.
once you've minimized the drift, work on how you squeeze the trigger to eliminate the drift.
then get to the gun range and strut.
