A NAA mini-revolver in .22 mag is one of the few firearms I have bought, owned, and then sold in less than six months.
Concept seemed cool, until I actually shot it.
No, I was not expecting any sort of accuracy at all.
However, I could not make it print on a 24 inch by 24 inch hunk of cardboard while shooting off a rest from only 9 feet.
Nine feet....that's three good steps........and I couldn't reliably hit something bigger than most human torsos. I had equal trouble hitting 2-liter pop bottles on the ground from about 5 feet.
If the bad guy is that close, I think I good solid punch to the face would probably have more immediate effect than a .22 mag launched out of such a short barrel.
