Yanno, if you got your family involved in
shooting sports, they could help defend you.
If you have an AK already, why not a pistol in a lower caliber.
Much easier to use inside a building, like a 9mm?
The shorter barrel of a K is going to give you muzzle blast/flip
to make it harder to get back on target, as well as
over-penetration, in a home setting.
