The chart in post #14 is for for gun in the right hand, one hand only. If you're right handed (assuming centered sights) and using both hands, low left is your trigger manipulation. Just plain left often is finger placement on the trigger.
We have two Shield 2.0 in 45 and 40 - both shot left for my wife and I. You'll get lots of advice about changing your shooting grip, etc., but I simply drifted the FRONT sights until they were on the precise point of aim and impact with normal shooting grip. Not one single problem since.
I have the "shooting left" problem with my BG 2.0. Will probably push the rear sight a bit to correct. I carry the gun, regardless. In close quarters, the difference between POA and impact is still a solid center mass hit.
