What sight picture are you using? (Dead center hold, or 6 o'clock?). What ammo? How many rounds have you put down range? How do you shoot with other platforms?
The is not meant as an insult, but f you are newer to shooting, or newer to that particular handgun, anticipating recoil is one of the biggest factors in driving rounds low. Gripping too tight or using toouch trigger finger or too little trigger finger inside the trigger guard can drive the gun to the left. (Don't know if you are right or left handed).
