If it were me I would go with the Rangers or the Gold Dots, both are good rounds. I like a heavier bullet for SD over a light one. They lend themselves towards more penetration if they expands or not and I don't think over penetration will be a concern with either of them.
I'm also not a fan of powerballs at all.
If the pain is lacking so is the discipline...
