James explores the idea of using a carbine chambered in a pistol cartridge for home defense (emphasis mine):

The fact that carbines are larger than handguns, and that they are fired while braced against the shoulder, means that the perceived recoil is almost unnoticeable even if you are using Magnum ammunition. A few of my students who were suffering from disabilities painful enough to keep them from using handguns, rifles, or shotguns for their defense had great success when they used carbines. Accurate, light, relatively inexpensive, easy to use. They were literally the answer to a few prayers.

I had not considered before the benefits they would offer to a person with certain disabilities.
