Smaller - thinner guns are sometimes are harder to shoot because of their size. Make sure your gun is unloaded (ammo in a different room) place the pad of your shooting index finger on the trigger, then get your grip, with your support hand fill in with your grip, you want 100% grip with both hands but broken down to 60% support hand 40% shooting hand, then press your trigger straight to the rear, do not tighten your grip as you press the trigger. Only at the range-get you some dummy rounds in your caliber mix dummies with live ammo at the range and shoot, if you see your gun move on a dummy then you can use a chart. You can also get someone to help watch you shoot (hopefully an instructor) to help fix your problem. Remember only think about your front sight not about the gun going off. Hope this helps stay safe.
