I was practicing this morning and I think it's in my grip. I have good positioning, it's just with shooting slow at the range, not trying for quick follow up shots, my grip just didn't have to be that tight.
3) The biggest thing I found I was doing was relaxing my grip after each shot making follow up shots slow and unsteady.
So next time I'm out at the range (soon I hope!), I'll try focusing on my grip and see how I do.
