Have you bench tested your guns with various types and brands of ammo? If your gun doesn't "like" what you feed it, it's not going to shoot well no matter what you do.
At ten yards, rested, off a bench with a GP100, all 6 shots making one ragged hole is not too much to expect. Use a target with a dot about the size of a nickle, not a man target. I am not familiar with SR9's enough to know what to expect.
