Only problem with the NAA is they have abysmal accuracy. My late wife bought one. I took it to the range and found that even using 2 hands and bracing against the lane divider I could not get it to produce any kind of meaningful group until the range was about 10-15 feet at most.
The tiny NAAs are not intended for distance shooting. They are unabashed belly guns, meant for point blank to maybe 6 feet, when a perp is violating your personal space. Even a Ruger LCP is questionable beyond 10 feet for most people.
