Thoughts?

I strongly disagree w/ his endorsement of the 22 Mag as a self defense round for cc, especially in the NAA derringer.

The Hornady 45 gr 22 Mag load developed for self defense shot generates only 843 fps when fired from a 2" barrel. "Ballistics by the Inch." The NAA 22 Mag is only 1 5/8" long. That's basically like using a subsonic 22 LR round for self defense. Plus, I've shot enough 22 rimfire rounds through the years to know that misfires are much to common for a rimfire to serve as a serious self defense round.
