This is huge one for me. On days that I'm calm and relaxed it all goes well and the improvement continues. On days where something has me frazzled its like starting over again. On those days, every pull has to be calculated and walked through step by step or I'm all over the target from anticipating every shot.
Practice, practice, practice and then we practice some more.
For shooting groups and learning to really shoot the gun and know where it hits, nothing beats a front site focus.
There are lots of focus types. There are books on the subject. There are many threads on the forum, esp in the competition section, on the subject. But that's getting way advanced for this new shooter who doesn't even have their gun yet. I believe in "walk before you run" and wouldn't advise someone start with a target focus and have them expect to ever resolve accuracy/precision issues.
When the shooter gets to the point they aren't always hitting left and the groups tighten up reasonably, then is the time to experiment with where we focus.
This all coming from a guy who using a more target focus a LOT.
