Here's a pic I took of 4 different ammo (9mm but anyway you get the idea) that could be a good option. Forget the last two (far right). Glaser, GECO are 2 bullets that can be used at home with very little risk. Both have enough stopping power at close range while not being able to punch through walls. Not sure if GECOs are made in .45. Only get them in 9mm.
