I live in a neighborhood where houses are kind of close, and there are alot of young kids around, not to mention my inside walls are all made of panelling, and there's no drywall.

That being said, I have a 9mm m&p full size and am not sure what the best home defense round might be. Should I only be looking at 115 grain rounds? Is 124 too much? Should I consider anything with +p+?

Heaven forbid anything actually happen, but if it did, I don't want rounds going through other house or anything like that.

Please help!
