Place the pistol in the hand so that the barrel is in line with the forearm. Trigger control with the Glock is an issue for some folks, and I'm one of them! For best results, the trigger finger must be placed differently on the trigger for a long pull than for a short, but with the Glock you must transition from one to the other between shots without moving your finger. Thus on the long pull you strain your hand if you use the fingertip placement, and you wobble the muzzle if you use the first knuckle placement with the short pull. Keep shooting! Practice dry firing! Concentrate on the front sight, keep your grip consistent each time your grasp the gun. If you can help it, don't allow the gun to sit askew in the hand, keep your grip high on the stock. You might not be able to if the gun is too large for you. If the gun muzzle flips up when you fire, adjust your grip so that the recoil comes straight back. Consentrate on a surprise break. Follow through. Don't over think it. Don't try to make your groups too small, if you rounds do not fall within 4" of your aiming point you are firing too fast, if they fall well with 4" of your aiming point you are firing too slow. It will come together.
