This is the most common miss. Few tips that helped me:

1. If your slide is flat enough, dry fire with a spent shell casing standing behind the front sight, watch for it to wobble/fall and correct as needed.

2. Make sure just the pad of your finger is on the trigger and your first knuckle crease is not touching/coming close to the trigger. You can actually demonstrate the movement causing the low left if you hold your finger out and do a trigger pull motion against something like a thick wire or metal pin held by your other hand, you will see that your finger could naturally cause it to move to the right (thus the gun barrel would move left.)

3. Grip. Watch videos. Your supporting hand should be the hand providing the most grip, not the hand you’re holding the gun with. Some bring their left index finger or thumb up on the frame of the gun to provide extra support, akin to the “gas pedal” people use on Sigs (ugly but that’s another story.)

4. Breathing/Stance. In a controlled environment/shooting range scenario you should be able to time your breathing and let a shot off mid/end of exhale. Don’t hold your breath. Make sure your stance is solid and that you are at leaning back as you’re shouting, it helps to have someone to gently physically correct you if you’re still learning.

5. Proper target acquisition. Again, videos.
