I've posted this in other threads here also although some may think it's a waste of time/money but it helps me.
I bought a little cheap-o ($20 on amazon) laser sight to clamp on the rail, clamp it on and adjust the red dot to match the sight allignment for a 6oclcok hold at 10 yds, practice a little but of dry fire, start from low ready to on target, press the trigger and watch the Red dot til the click, observe your grip and the sights, build a muscle memory for point and shoot.
As said do this for a while dry firing, rack the slide, point and click. Watch what happens to the dot on paper, this can even be done at home before going to the range.
At the range the dot will show you any errors of compensating/anticipating the recoil ie: pushing the pistol forward or a torque in your grip method and yanking the trigger.
The cheap laser sight will eventually lose "zero" after a couple mags of ammo, but by then you should have a good rhythm of putting rounds on target.
