A shotgun is a formidable home protection weapon. I let google enlighten me. It strikes me as being way under powered but at least it is something. Single shot 410 is what I found. I would think that a local gun store might have your charmer or could order you one in. It's a shame that you don't live in a gun friendly state. Here in Kansas I have a Kel-Tec KSG Bullpup for my home protection. Pump action with six rounds of 12 gauge buck and six rounds of slugs and one shell hot.
