The Glaser Safety Slug provides the best in-home choice, when over penetration is an issue. This bullet will not endanger persons in adjacent rooms or dwellings. It is however very effective on any soft target it hits. A possible self-defense plan might include using a magazine or speed loader of Glaser Safety Slugs in the home; then switching to a higher penetrating load such as Pow’RBall or DPX when you carry outside the home.
