Sounds more like trigger engagement, i.e. not enough of your index finger in front of the trigger causing you to torque the gun to the left.
I prefer to have the right edge (I shoot right handed) of the trigger nestled into the first joint of my trigger finger. This puts the trigger centered in the first pad of my index finger.
Try dry firing (no ammo of course)with your sights centered on a light switch or wall outlet and see what happens as you pull the trigger. It shouldn't move nor should you have to struggle to keep the weapon on target if you have proper trigger engagement/grip.
If you have adequate trigger control, it could just be the gun needs to be sighted to your point of aim with a simple windage adjustment.
Flinching usually prints low and left.
Hope this helps,
