You definitely have a "flinch" and you're right-handed because several of your shots were pulled way right when you jerked the trigger.
John's advice is dead-on! You're going to have to overcome your habit of "anticipating the shot", as it causes you to yank
the trigger back intead of "pressing" it to the rear.
My advice would be to practice with standard
or target velocity
.38 Specials for a period of time until you are able to "call" your shot placement every time you squeeze off a round. And yes, get your sights corrected so you'll have a better sight picture, which translates to a tighter grouping.
Practice, practice and more practice! You're doing fine, kid!
