Whenever shooting indoors make sure you ALWAYS know what you are shooting at. I saw the news a few days ago-- in Florida this old guy killed his longtime girlfriend (accidently). You can rest assured a commercial .38 is not going to go through sheet rock after you hit THE initial perpetrator/target. After shooting a few dozen rounds with your gun you don't have to line up your shot as much on a target with a foot of radius, and you can also walk around your place in the dark and learn your surroundings better. I found that a .38+P JHP with the cuts on it do the job very well.
