If you do have a tight pattern that was low and left, why would you say you were making consistent mistakes?
In scanning this forum, and Youtube, there are many postings giving very different explanations for the bullets consistently going to the wrong place. Limp wristing, wrong grip, wrong position of the supporting hand, and many other faults, which vary from one posting to the next.
If you do have a consistent and acceptably tight pattern, it would seem, that you are either aligning your sights in some wrong way, or you simply need to adjust your sights to move the pattern.
Are you now relaxed enough so that you can see the sight aim point when the round is fired? Work on that before you change anything.
I'm a rifle shooter for over 72 years, but have been shooting pistols (other than random plinking at mistletoe) for only 3 years, but I have been able to see where the gun is pointed when it fires and the bullets seem to go to that place.
