The .22 magnum NAA mini's fire .22 magnum.
I prefer the .22lr NAA's, since even with .22lr, the recoil combined with lack of grip still has some muzzle flip. The gun is fun as all get out though. Great belly gun, dog walking gun, or for dispatching critters.
The guns are typically well made, and hold their value. There are some variants that are pretty cool, like a top break action, or swing out cylinder. The pug is cool, I haven't shot one. I would imagine the extra weight out front would mitigate some of the muzzle flip.
As to the guy in this thread that dropped his, and it fired, I don't know what on earth he was doing, but there's a notch in the cylinder that the hammer drops into that secures the hammer in place. The only way I can thing it went off is if SOMEHOW he dropped it in such a way that one of the other rounds on the sides of the cylinder was struck by a sharp object. But even that would be hard to believe.
They did have different generations of design, the very early NAA Mini revolvers don't have the safety notch, all the other ones do.
