I am going to attempt to keep this moving in a positive direction for you here. I have a question: are you shooting low and left as well?

There is a strong tendency to push the muzzle down and to the left when you first start shooting a DA snub. I strongly urge you to see where it shoots with someone familiar with this type of revolver.

Bullets lighter than 158gr can often print low as well. I am curious what type ammo you are using.
