You have completely lost me; and I've taught pistol shooting, now, for many years! I have no idea how this conclusion can be drawn from any of the OP's initial remarks? This said: Every woman I know who owns or carries an LC9, hates the trigger and has trouble shooting the gun - No exceptions!You are probably sticking your finger too far on to the trigger. Try no more than your first joint of your finger tip. You can unload the gun and practice dry firing. you don't need to go to the range to do this just make sure the gun is empty and practice away.
(And one of these women is a local gun dealer's wife whom I'm positive is soon going to be carrying something else!)
