Six words get you the best of the NAA minis:
Black Widow, small sights, dual caliber.
The .22Mag does give you more power, with careful ammo selection. The BW is inherently more accurate, and the sights are usable. And by swapping the big rubber grips down to the smaller "Magnum Mini" wood bird's head, the 2" barrel is still "pocketable".
Do most of your practice with .22LR, esp. at first. But the Magnums ARE controllable and usable
