You didn't say what distance your target was set at, but sometimes if you set your target say at 5 or 7 yards or even closer, shoot a few mags and really concentrate on your sights and slowly pulling the trigger. You'll gain confidence and start accepting the recoil without thinking about it. Shooting at a greater distance trying to figure out what you're doing wrong will only make the problem worse. You do have a fairly good group so whatever you are doing, you are doing it the same each shot.
Another thing is to get some snap caps and have someone load one or two mags mixing the snap caps with your ammo. You won't know when the snap cap comes up and if you are pushing the gun when the snap cap is chambered it will exaggerate what you are doing wrong.
Next, keep shooting. The more you shoot the more comfortable you become.
Also, reverse the chart Dillinger sent, for left handed shooting.
