yep, right hand, left dominant eye, right eye not worth a flip

That explains a lot about your group opening up both right and left (mostly right). Two things: First, you need to teach yourself that RECOIL IS YOUR FRIEND! If the pistol doesn't recoil then you aren't going to be able to shoot it accurately at speed. Next, concentrate on your grip. Set your gun hand on the pistol and press it in, hard, from front to back.
Managing the size of your shot group begins with managing the way you press the pistol's backstrap into the web of your gun hand. Get this right; do it the same way every time, and I think you'll be surprised at how much better you're shooting.
Like most newbies you lack consistency; however, you also show real promise! Don't fight the recoil; learn how to work with it instead. Elsewhere, I've written, 'pages' on this particular topic. I don't feel like reiterating it all here and now. If you wish to study pistol grip dynamics PM me, and I'll pass some of what I have on file about this topic along to you.
